    Freesync
    What we Know?
    We believe FreeSync is to combat & show AMD trick up its sleeve vs Nvidia G-sync Technology

    General Information/News

    According to the company’s senior engineers, they can replicate much of the advantages of Nvidia’s G-Sync tech through the use of what are called dynamic refresh rates. Multiple generations of AMD video cards have the ability to alter refresh rates on the fly, with the goal of saving power on mobile displays. Some panel makers offer support for this option, though the implementation isn’t standardized. AMD engineers demoed their own implementation, dubbed “FreeSync,” on a laptop at the show

    Dynamic refresh rates would theoretically work like G-Sync by specifying how long the display remained blank on a frame-by-frame basis, providing for smoother total movement. AMD has stated that the reason the feature didn’t catch on was a lack of demand — but if gamers want to see G-Sync-like technology, AMD believes it can offer an equivalent. AMD also told Tech Report that it believes triple buffering can offer a solution to many of the same problems G-Sync addresses. AMD’s theory as to why Nvidia built an expensive hardware solution for this problem is that Nvidia wasn’t capable of supporting G-Sync in any other fashion.


    No Videos can be found at this stage that does not ruin the effect of FreeSync

    True Audio
    How AMD TrueAudio removes constraints on sound developers
    AMD TrueAudio technology is all about giving sound engineers the freedom to follow their imaginations and the power to make their games sound as convincing as they look. Here are some of the features that make that possible:
    A dedicated digital signal processor (DSP) is built in to the AMD GPU core. That’s a hefty dose of processing power committed just to generating immersive soundscapes. That doesn’t just enable new and exciting audio features in games; it also saves CPU cycles that can be used for other tasks.
    Programmable sound effects bring to audio the same kind of flexibility that programmable shaders brought to graphics. Game developers aren’t stuck with inflexible canned effects anymore. They now have the flexibility to create complex effects and acoustic environments.
    More voice channels and audio objects mean game developers no longer have the unenviable task of determining which sounds are expendable. AMD TrueAudio technology multiplies the number of sounds a game can generate at once, giving developers the capacity to create much more lifelike soundscapes.
    True to life echoes and convolution reverb are finally available on all platforms, meaning programmers can now build these effects into their games rather than relying on basic reverbs. The types of real-world acoustic phenomena that can be faithfully reproduced are massively greater.
    Multi-channel specialization brings in-headset surround sound with accurate positional audio algorithms to all gamers; not just the ones with the priciest headgear.

    What it means for gamers
    By leveraging AMD TrueAudio technology, game developers now have the ability to recreate acoustic environments with incredible fidelity, and to bring them to every gamer. With AMD technology inside all the most popular “next-generation” gaming platforms, including the PC, gamers across the entire industry will finally enjoy the best audio today’s technology can offer.

    Demonstration:



    Mantle
    Taken from Wikipedia
    Mantle is a graphics API specification developed by AMD as an alternative to Direct3D and OpenGL, primarily for use on the PC platform. Currently the only implementation is for graphics processing units with AMD's Graphics Core Next architecture.[4] The design goals of Mantle are to allow games and applications to utilize the CPU and GPU more efficiently, eliminate CPU bottlenecks by reducing API validation overhead and allowing more effective scaling on multiple cores, provide faster draw routines, and allow greater control over the graphics pipeline by eliminating certain aspects of hardware abstraction inherent to the current prevailing graphics APIs.

    AMD has stated that Mantle will be an open API. It is unknown when the Mantle specification and development materials will be released to the public, although AMD's director of software alliances and developer relations stated in an interview that Mantle may be made public in early 2014, or the year after.As of March 2014, the Mantle specification and development materials remain unavailable to the general public.

    Claimed Advantages
    Reduced runtime shader compilation overhead
    AMD claims that Mantle can generate up to 9 times more draw calls per second than comparable APIs by reducing CPU overhead.
    Performance increase over higher-level APIs such as Direct3D and OpenGL.
    Explicit command buffer control
    Up to 45% faster than Direct3D in Battlefield 4 and up to 319% faster in the Star Swarm demo in single GPU configuration in extremely CPU-limited situations.
    Better control over the hardware.
    "All hardware capabilities are exposed through the API."
    Low-overhead validation and processing of API commands
    Reduction of command buffer submissions
    Data formats optimizations via flexible buffer/image access
    Explicit control of resource compression, expansion, and synchronization
    Asynchronous DMA queue for data uploads independent from the graphics engine
    Asynchronous compute queue for overlapping of compute and graphics workloads
    Advanced Anti-Aliasing features for MSAA/EQAA optimizations
    New rendering techniques.
    Close to linear performance scaling from recording command buffers onto multiple CPU cores
    Multithreaded parallel CPU rendering support for at least 8 cores.
    No game developer reliance on existing AMD driver support release schedules (potentially no or fewer bugs on release, much faster patching for GFX related errors).
    Due to bypassing of error-prone and inefficient abstraction, common technical difficulties like FPS drops, micro stuttering and texture corruption can be significantly less frequent or nonexistent, though Mantle currently has these more commonly than DirectX and OpenGL.[citation needed]

    XDMA an enhancement to Crossfire
    Credit to AMD Blog Posted by rhallock in AMD Gaming on Jan 3, 2014 11:20:00 AM - See more at: http://community.amd.com/community/...lti-gpu-gaming-with-xdma#sthash.Qv6LNSxZ.dpuf

    A lesser-known feature of the AMD Radeon™ R9 290 and R9 290X is a new technology called AMD CrossFire™ Direct Memory Access, or “XDMA” for short. XDMA is a modernization of multi-GPU configurations that totally overhauls how these many GPUs communicate with one another and stay synchronized during intense gaming. Today we will explore how the feature functions, what problems it solves, and what scenarios it’s designed to accommodate.

    Before we explore the drastic improvements presented with XDMA, however, we should first start by exploring the old way of performing multi-GPU communication.

    THE OLD WAY OF DOING MULTI-GPU
    Intenal Components.pngPrior to the advent of XDMA, a “bridge” or “connector” of some fashion was required. This bridge was installed on the exterior of a graphics card, fitting onto small golden fingers protruding from the circuit board of the graphics card. You can see the connector to the right, where it has been installed on two AMD Radeon™ HD 7970 GHz Edition GPUs .

    An external bridge was considered a modern solution that gave two (or more) GPUs the ability to communicate on a very important task: copying data between the GPUs to show you a rendered frame of your favorite game.

    While the external bridge has been an effective multi-GPU solution for many years in the graphics industry, we are coming on an era when that is no longer the case. To wit, the bandwidths provided by today’s bridge solution are insufficient to fully accommodate the new generation of high-resolution 4K displays. As the AMD Radeon R9 290 and R9 290X are designed with this resolution in mind, it was time to bring in a fresh approach to multi-GPU systems.

    MODERN MULTI-GPU WITH XDMA
    Picture7.pngAt a principle level, XDMA dispenses with the external bridge by opening a direct channel of communication between the multiple GPUs in a system. This channel operates over the very same PCI Express® bus in which your AMD Radeon graphics cards are currently installed. The exclusive function of that bus is to shuttle graphics data between GPUs and your processor, so it’s already well suited to the new task of collecting and showing the data each GPU is working on when playing games.

    It just so happens that the PCI Express bus also provides a tremendous amount of bandwidth—far more than can be allocated to today’s external bridges! As noted by Anandtech in their comprehensive analysis of XDMA, the bandwidth of an external bridge is just 900MB/s, whereas PCI Express® can provide up to 32GB/s with a PCIe 3.0 x16 slot (about 35x more bandwidth).

    In dynamically taking a portion of that superhighway to negotiate rendering with multiple GPUs, AMD CrossFire can efficiently negotiate UltraHD scenarios. This is one of the many reasons why we say that the AMD Radeon R9 290 and R9 290X are uniquely suited, at a hardware level, for gaming at 3840x2160.

    Diving more deeply into the technology, XDMA specifically and directly connects the “display controllers” on the respective GPUs in an AMD CrossFire configuration. These display controllers are responsible for taking a rendered scene in a game from the GPU pipeline and formatting it to send over the display cable to a monitor. XDMA provides an easier and more extensible method of transferring the frame from the GPU it was rendered on, to the GPU driving the display cable, using the high bandwidth of PCIe, while avoiding extra connectors and cables.

    FACTS ABOUT XDMA
    Rather than dig through more technical jargon, we wanted to jump to some essential facts that we wanted you to know about this great technology:
    XDMA is a unique solution in the graphics industry; no similar technologies presently exist for consumer GPUs.
    In case you didn’t catch it, XDMA eliminates the need to install any bridge. Install matching GPUs and you’re set!
    XDMA is designed for optimal performance with systems running PCI Express 2.0 x16 (16GB/s), PCI Express 3.0 x8 (16GB/s), or PCI Express 3.0 x16 (32GB/s).
    Bandwidth of the data channel opened by XDMA is fully dynamic, intelligently scaling with the demands of the game being played, as well as adapting to advanced user settings such as vertical synchronization (vsync).
    Designed for UltraHD via DisplayPort™, which permits for 2160p60 gaming on the AMD Radeon R9 290 Series.
    XDMA fully supports the “frame pacing” algorithms implemented into the AMD Catalyst™ driver suite.
    Products without XDMA are scheduled to receive a new AMD Catalyst driver in January that will resolve uneven frame pacing as a symptom of the more limited bandwidth provided by an external bridge.

    AMD Gaming Evolved Game DVR
    adds continuous recording with virtually no performance cost

    The Gaming Evolved client has always been designed to enhance as many aspects of your PC gaming as possible,
    and with the introduction today of new, automated DVR and streaming features, we’re taking that concept to another level.


    Just like the popular feature many people use with their TVs, the new DVR feature is always recording your gameplay, making up to the last 10 minutes available for replay, saving and sharing. The next time you bust an astounding move, you’ll be able to share it with all your friends. The feature is intended to be left always on, so you never have to worry about forgetting it, and the overhead required to keep it running in the background is minimal. It’s a terrific way of saving and sharing your best moments, including the ones you didn’t plan for.
    As great as DVR is, sometimes a recording is not what you’re after and only live action will do. For that, we’re happy to announce that Twitch is now integrated into the AMD Gaming Evolved Client. Twitch is the leading platform for live game streaming. Now you can use it to share live gameplay, broadcast tournaments and show your skills to the world, all from within the AMD Gaming Evolved Client.

    TressFX
    What is TressFX
    TressFX Hair revolutionizes in-game hair by using the DirectCompute programming language to unlock the massively-parallel processing capabilities of the Graphics Core Next architecture, enabling image quality previously reserved for pre-rendered images. Building on AMD's previous work on Order Independent Transparency (OIT), this method makes use of Per-Pixel Linked-List (PPLL) data structures to manage rendering complexity and memory usage.

    What Can TressFX do?
    Finally, hair styles are simulated by gradually pulling the strands back towards their original shape after they have moved in response to an external force. Graphics cards featuring the Graphics Core Next architecture, like select AMD Radeon™ HD 7000 Series GPUs, are particularly well-equipped to handle these types of tasks, with their combination of fast on-chip shared memory and massive processing throughput on the order of trillions of operations per second. - See more at: http://community.amd.com/community/...volutionary-tressfx-hair#sthash.vpLKdUVS.dpuf

    What Games Support TressFX

    What is Heterogeneous Computing?
    Many in the industry have adopted the term “heterogeneous computing” to describe an approach that tightly integrates CPUs, GPUs, DSPs and other programmable accelerators into a single System on Chip (SoC).
    Processor architects apply three broad templates to the chips they design, depending on the specific tasks the chip must handle.
    Their most general design, known as a Central Processing Unit (CPU), addresses the wide range of tasks required to run an operating system and support application programs such as web browsers, word processors and video games.
    CPUs struggle with the massive calculations needed to manipulate 3-D images on a computer display in real time, so chip architects devised specialized Graphics Processing Units (GPUs) to handle these types of parallel operations.
    Contemporary GPUs not only accelerate a broad range of parallel computations; they also help reduce the energy needed to perform those operations, a desirable feature in power-constrained environments.
    Conventional CPU designs also struggle when called upon to support high-speed streaming data in digital communications systems and audio applications, along with a variety of other low latency, compute-intensive tasks, so specialized units, known as Digital Signal Processors or DSPs, emerged to handle these workloads.
    DSPs embedded in your cell phone convert the analog signals in your speech into a stream of bits, move those bits to the nearest cell phone tower using a variety of radio protocols, and then convert any received digitized voice signals back into a form you can hear using the phone’s speaker.
    That same DSP also handles the data you send and receive via WiFi and any Bluetooth communications between your tablet and its keyboard.

    Programmable devices optimized for these diverse workloads evolved independently for several decades, and designers often included all three flavors of chips in the systems they assembled. Increased transistor budgets now allow designers to place CPU, GPU and DSP elements onto a single System on Chip (SoC).
    This physical integration enables smaller devices, reduces cost and saves power, since on-chip communication uses far less energy than connecting chips via a motherboard or substrate.
    The co-location of these logic blocks on a single slab of silicon is just the beginning. To gain the full benefits of integration, separate functions need shared access to the data they process.
    Getting these diverse processor personalities to work as a team is no easy task; as with any team-building exercise, a manager needs to help the team members work together. The creation of a model that presents these features in a manner comprehensible to mainstream software developers, and supported by their development environments, is a more challenging task.
    We’ll examine moves the industry is taking to address these issues a little later in this document.

    Why does Heterogeneous Computing matter?
    Today’s computer users want to handle a wide variety of tasks and interact naturally with their systems. Instead of typing on a keyboard and pointing with a mouse, they want to aim their phones and tablets at a scene, pinch and zoom the image they see on the display, and capture a great photo.
    They expect their systems to recognize faces, track eye movements and respond to complex inputs (touch, voice and gestures) in real time. When playing games, they want the objects they blow up to explode realistically, with full visual and physical fidelity. They want batteries that last a long time on a single charge.
    These new user experiences place far greater computational demands on system resources than the usage models of just a few years ago. Conventional CPU designs cannot meet the response time expectations these new workloads demand, especially on limited power budgets. Fortunately, much of this work fits nicely with the talents GPUs and DSPs bring to the table.
    GPUs can easily extract meaning from the pixels captured by a camera, and transform those pixels into objects a CPU can recognize. DSPs have long played a key role in voice and image processing systems. These different processing elements have long been available, albeit packaged discretely. Clever programmers have been able to cobble together proofs of concept that demonstrate what this technology can accomplish.
    The challenge the industry now faces is to integrate these capabilities into standard environments that simplify the programming task for the broader community of software developers who haven’t had an opportunity to earn a PhD in computer science from Stanford or MIT.

    Will HSA make the smartphone, tablet or laptop I just bought run better?
    Odds are that system you bought in 2013 includes an SoC that integrates CPU and GPU technology and perhaps a DSP as well. The concept of co-locating all these processors on a single piece of silicon has been around for a few years, and most hardware vendors have adopted it in one form or another. As we’ve noted elsewhere, HSA takes this integration to the next level, by allowing these processors to work harmoniously in a shared memory environment. This aspect of HSA is so new it won’t be available in any systems planned for shipment in 2013. The systems you can buy today deliver better battery life and performance in thinner and lighter form factors than the ones you could buy a few years ago, but as the song goes, you ain’t seen nothing yet. Between now and then, enjoy your new device, and be sure to download the latest apps that take advantage of the integrated features in today’s hardware.
    What workloads benefit the most from HSA?
    HSA makes it easier to deploy CPU and GPU resources harmoniously to execute application programs, so it makes sense that the applications that benefit the most include those that spend a lot of time performing calculations that can be done in parallel on a GPU. (
    The CPU side of a current quad-core SoC can deliver around 100 GFLOPS, while the GPU side offers peak rates approaching 700 GFLOPS5). Although CPU resources are more than adequate for most traditional scalar workloads, they struggle when called on to analyze images, sort through vast databases, or interact with users via “natural user interfaces.” Fortunately, these latter tasks are just the ones that benefit the most from the GPU on the SoC; it’s just a matter of adapting applications to become “HSA-aware.”

    Dynamic Super Resolution: 4K-Quality Graphics On Any HD Monitor

    Our new Maxwell architecture introduces a raft of innovative, exciting technologies that make your games better in dramatic ways. Of these new features, Dynamic Super Resolution (DSR) is most immediately impactful, enhancing any game that supports resolutions above 1920x1080. What does DSR do? Simply put, it renders a game at a higher, more detailed resolution and intelligently shrinks the result back down to the resolution of your monitor, giving you 4K-quality graphics on any screen.



    Enthusiasts with compatible monitors and technical knowledge refer to this process as Downsampling, and for some time they've been applying a basic version to improve fidelity in games. DSR improves upon this process by applying a high-quality Downsampling filter that significantly improves image quality, by making Downsampling compatible with all monitors, by removing the need for technical know-how, and by integrating DSR into GeForce Experience, enabling gamers to apply DSR Optimal Playable Settings with a single click.

    [​IMG]

    o make DSR easy to use we've incorporated it into our GeForce Experience Optimal Playable Settings: if your GPU has the performance to play a game at 4K, DSR will be recommended. One click-optimize applies the setting and you're good to go. If the game has a user interface that does not scale correctly with the resolution, we won't recommend DSR.

    If you still want to enable DSR manually for a game, you can enable it by selecting the DSR resolution in the Optimal Playable Settings customizer dropdown:
    [​IMG]

    You can also use the NVIDIA Control Panel to fine tune DSR and filtering smoothness.

    As of today, DSR is only supported on new GeForce GTX 900 Series GPUs, but in the future we'll be rolling out this incredible new feature to other, similarly powerful NVIDIA GeForce GTX graphics cards. For more information on the inner workings of DSR, please check out our dedicated Dynamic Super Resolution article.

    4K ShadowPlay Recording

    GeForce GTX 900 Series GPUs, like the newly-released GeForce GTX 980 and GeForce GTX 970, include an enhanced H.264 hardware encoder, further reducing the already-minimal performance of GeForce Experience's ShadowPlay gameplay recorder. This improved hardware also enables the recording of footage at Ultra HD resolutions, beginning with 3840x2160, commonly referred to as "4K".

    Recording at up to 60 FPS, at bitrates of up to 130 Mbps, ShadowPlay 4K gameplay captures are the best way to get your favorites moments onto YouTube in Ultra HD resolutions, with the absolute best quality possible. And as with 1920x1080 and 2560x1440 captures, all ShadowPlay recording modes, features, and options are available, letting you tailor your recordings to your personal preferences.














    G-SYNC
    What is G-SYNC
    NVIDIA G-SYNC is ground breaking new display technology that delivers the smoothest and fastest gaming experience ever.
    G-SYNC’s revolutionary performance is achieved by synchronizing display refresh rates to the GPU in your GeForce GTX-powered PC, eliminating screen tearing and minimizing display stutter and input lag.
    The result: scenes appear instantly, objects look sharper, and game play is super smooth, giving you a stunning visual experience and a serious competitive edge.

    The Problem: Old Tech
    When TVs were first developed they relied on CRTs which work by scanning a beam of electrons across the surface of a phosphorus tube. This beam causes a pixel on the tube to glow, and when enough pixels are activated quickly enough the CRT can give the impression of full motion video. Believe it or not, these early TVs had 60Hz refresh rates primarily because the United States power grid is based on 60Hz AC power. Matching TV refresh rates to that of the power grid made early electronics easier to build, and reduced power interference on the screen.
    By the time PCs came to market in the early 1980s, CRT TV technology was well established and was the easiest and most cost effective technology for utilize for the creation of dedicated computer monitors. 60Hz and fixed refresh rates became standard, and system builders learned how to make the most of a less than perfect situation. Over the past three decades, even as display technology has evolved from CRTs to LCD and LEDs, no major company has challenged this thinking, and so syncing GPUs to monitor refresh rates remains the standard practice across the industry to this day.
    Problematically, graphics cards don’t render at fixed speeds. In fact, their frame rates will vary dramatically even within a single scene of a single game, based on the instantaneous load that the GPU sees. So with a fixed refresh rate, how do you get the GPU images to the screen? The first way is to simply ignore the refresh rate of the monitor altogether, and update the image being scanned to the display in mid cycle. This we call ‘VSync Off Mode’ and it is the default way most gamers play. The downside is that when a single refresh cycle show 2 images, a very obvious “tear line” is evident at the break, commonly referred to as screen tearing. The established solution to screen tearing is to turn VSync on, to force the GPU to delay screen updates until the monitor cycles to the start of a new refresh cycle. This causes stutter whenever the GPU frame rate is below the display refresh rate. And it also increases latency, which introduces input lag, the visible delay between a button being pressed and the result occurring on-screen.
    Worse still, many players suffer eyestrain when exposed to persistent VSync stuttering, and others develop headaches and migraines, which drove us to develop Adaptive VSync, an effective, critically-acclaimed solution. Despite this development, VSync’s input lag issues persist to this day, something that’s unacceptable for many enthusiasts, and an absolute no-go for eSports pro-gamers who custom-pick their GPUs, monitors, keyboards, and mice to minimize the life-and-death delay between action and reaction.

    Enter NVIDIA G-SYNC, which eliminates screen tearing, VSync input lag, and stutter. To achieve this revolutionary feat, we build a G-SYNC module into monitors, allowing G-SYNC to synchronize the monitor to the output of the GPU, instead of the GPU to the monitor, resulting in a tear-free, faster, smoother experience that redefines gaming.
    Industry luminaries John Carmack, Tim Sweeney, Johan Andersson and Mark Rein have been bowled over by NVIDIA G-SYNC’s game-enhancing technology. Pro eSports players and pro-gaming leagues are lining up to use NVIDIA G-SYNC, which will expose a player’s true skill, demanding even greater reflexes thanks to the unnoticeable delay between on-screen actions and keyboard commands. And in-house, our diehard gamers have been dominating lunchtime LAN matches, surreptitiously using G-SYNC monitors to gain the upper hand.
    Online, if you have a NVIDIA G-SYNC monitor you’ll have a clear advantage over others, assuming you also have a low ping.

    PhysX
    [​IMG]
    What is NVIDIA PhysX Technology?
    NVIDIA® PhysX® is a powerful physics engine enabling real-time physics in leading edge PC games.
    PhysX software is widely adopted by over 150 games and is used by more than 10,000 developers. PhysX is optimized for hardware acceleration by massively parallel processors.
    GeForce GPUs with PhysX provide an exponential increase in physics processing power taking gaming physics to the next level.

    What is physics for gaming and why is it important?
    Physics is the next big thing in gaming. It's all about how objects in your game move, interact, and react to the environment around them. Without physics in many of today's games, objects just don't seem to act the way you'd want or expect them to in real life. Currently, most of the action is limited to pre-scripted or ‘canned' animations triggered by in-game events like a gunshot striking a wall. Even the most powerful weapons can leave little more than a smudge on the thinnest of walls; and every opponent you take out, falls in the same pre-determined fashion.
    Players are left with a game that looks fine, but is missing the sense of realism necessary to make the experience truly immersive. With NVIDIA PhysX technology, game worlds literally come to life: walls can be torn down, glass can be shattered, trees bend in the wind, and water flows with body and force.
    NVIDIA GeForce GPUs with PhysX deliver the computing horsepower necessary to enable true, advanced physics in the next generation of game titles making canned animation effects a thing of the past.


    Which NVIDIA GeForce GPUs support PhysX?
    The minimum requirement to support GPU-accelerated PhysX is a GeForce 8-series or later GPU with a minimum of 32 cores and a minimum of 256MB dedicated graphics memory. However, each PhysX application has its own GPU and memory recommendations. In general, 512MB of graphics memory is recommended unless you have a GPU that is dedicated to PhysX.

    How does PhysX work with SLI and multi-GPU configurations?
    When two, three, or four matched GPUs are working in SLI, PhysX runs on one GPU, while graphics rendering runs on all GPUs. The NVIDIA drivers optimize the available resources across all GPUs to balance PhysX computation and graphics rendering. Therefore users can expect much higher frame rates and a better overall experience with SLI.
    A new configuration that’s now possible with PhysX is 2 non-matched (heterogeneous) GPUs. In this configuration, one GPU renders graphics (typically the more powerful GPU) while the second GPU is completely dedicated to PhysX. By offloading PhysX to a dedicated GPU, users will experience smoother gaming.

    Why is a GPU good for physics processing?
    The multithreaded PhysX engine was designed specifically for hardware acceleration in massively parallel environments.
    GPUs are the natural place to compute physics calculations because, like graphics, physics processing is driven by thousands of parallel computations.
    Today, NVIDIA's GPUs, have as many as 480 cores, so they are well-suited to take advantage of PhysX software.
    NVIDIA is committed to making the gaming experience exciting, dynamic, and vivid. The combination of graphics and physics impacts the way a virtual world looks and behaves.

    Can I use an NVIDIA GPU as a PhysX processor and a non-NVIDIA GPU for regular display graphics?
    No. There are multiple technical connections between PhysX processing and graphics that require tight collaboration between the two technologies.
    To deliver a good experience for users, NVIDIA PhysX technology has been fully verified and enabled using only NVIDIA GPUs for graphics.

    can i use an AMD card?
    PhysX supports both CPU and GPU simulation. GPU simulation is only available on Nvidia graphics card irrespective of CPU.
    Well written application usually check for GPU simulation support and allow for CPU fallback if its not present.
    However, CPU PhysX can seriously effect Framerate

    SLI
    Quick Understanding
    SLI is the technology that combats AMD's Crossfire Technology, however you can not mix ram sizes with SLI. GPU with 2GB ram will not SLI with a GPU of the same model with 4GB ram

    WHAT IS SLI
    NVIDIA SLI intelligently scales graphics performance by combining multiple GeForce GPUs on an SLI certified motherboard. With over 1,000 supported applications and used by over 94% of multi-GPU PCs on Steam, SLI is the technology of choice for gamers who demand the very best.
    SLI features an intelligent communication protocol embedded in the GPU, a high-speed digital interface to facilitate data flow between the two graphics cards, and a complete software suite providing dynamic load balancing, advanced rendering, and compositing to ensure maximum compatibility and performance in today’s latest games.

    Features
    Beyond just better performance, SLI offers a host of advanced features. For PhysX games, SLI can assign the second GPU for physics computation, enabling stunning effects such as life-like fluids, particles, and destruction. For CUDA applications, a second GPU can be used for compute purposes such as Folding@home or video transcoding. Finally, for the ultimate in image quality, SLI antialiasing offers up to 64xAA with two GPUs, 96xAA with three GPUs, or 128xAA with four GPUs.

    Scaling
    Thanks to Fermi’s architectural innovations, SLI scaling is higher than ever. Across many popular titles, over 80%, and at times 100% performance improvement, can be obtained by adding a second GPU.
    [​IMG]

    Not just Multiple Video Cards
    When SLI was first introduced the technology was used only to connect multiple video cards. In 2005, however, Gigabyte introduced a video card that used SLI technology to connect two different Nvidia GPUs located on the same video card.
    This arrangement has become more common over time. Both Nvidia and AMD have released reference design cards featuring two GPUs in the same video card connected via SLI or CrossFire.
    This has confused things a bit because two video cards with two GPUs each would technically be a quad-SLI arrangement even though only two video cards are involved. With that said, these cards are expensive and thus rare, so you can generally assume that if someone is talking about SLI they are talking about the use of two or more video cards.
    SLI usually describes a desktop solution but it is available in gaming laptops. AMD sometimes pairs its APUs with a discrete Radeon GPU, which means you’ll sometimes run across CrossFire laptops that only cost $600 to $800 bucks.
    Nvidia has also paired a discrete GPU with an integrated GPU in the past. This was branded with the term Hybrid SLI. Nvidia was forced out of the chipset business soon after, however, which meant the company no longer offered integrated graphics. Hybrid SLI is effectively dead as a result.

    3D Vision

    3D Vision Vision
    http://www.nvidia.co.uk/object/3d-vision-main.html
    3D Vision (previously GeForce 3D Vision) is a stereoscopic gaming kit from Nvidia which consists of LC shutter glasses and driver software which enables stereoscopic vision for any Direct3D game,
    with various degrees of compatibility. There have been many examples of shutter glasses over the past decade, but the NVIDIA 3D Vision gaming kit introduced in 2008 made this technology available for mainstream consumers and PC gamers.
    The kit is specially designed for 120 Hz LCD monitors but is compatible with CRT monitors (some of which may work at 1024×768×120 Hz and even higher refresh rates), DLP-projectors, and others.
    It requires a compatible graphics card from Nvidia (GeForce 200 series or later).

    Shutter Glasses
    The glasses use wireless IR protocol and can be charged from a USB cable, allowing around 60 hours of continuous use.
    The wireless emitter connects to the USB port and interfaces with the underlying driver software. It also contains a VESA Stereo port for connecting supported DLP TV sets, although standalone operation without a PC with installed Nvidia 3D Vision driver is not allowed.
    NVIDIA includes one pair of shutter glasses in their 3D Vision kit, SKU 942-10701-0003. Each lens operates at 60 Hz, and alternate to create a 120 Hz 3-dimensional experience.
    This version of 3D Vision supports select 120 Hz monitors, 720p DLP projectors, and passive-polarized displays from Zalman.

    Stereo Driver
    The stereo driver software can perform automatic stereoscopic conversion by using the 3D models submitted by the application and rendering two stereoscopic views instead of the standard mono view. The automatic driver works in two modes: fully "automatic" mode, where 3D Vision driver controls screen depth (convergence) and stereo separation, and "explicit" mode, where control over screen depth, separation, and textures is performed by the game developer with the use of proprietary NVAPI.
    The quad-buffered mode allows developers to control the rendering, avoiding the automatic mode of the driver and just presenting the rendered stereo picture to left and right frame buffers with associated back buffers.

    How many displays do I need to run 3D Vision Surround?
    3D Vision Surround requires three displays or projectors. You can use a variety of displays, including LCD monitors, TVs, or projectors. Please view the 3D Vision Surround system requirements for a full list of supported products
    Please note: NVIDIA 3D Vision Surround and NVIDIA Surround does not support a two display surround configuration. Both NVIDIA 3D Vision Surround and NVIDIA Surround require three supported displays as defined in the system requirements above.

    Does 3D Vision Surround support 2D displays?
    Yes, you can run Surround in 2D mode. We call this mode Surround (2D). Make sure that 3D Vision is disabled from the Stereoscopic 3D control panel to use Surround (2D) mode.

    What GPUs does 3D Vision Surround support?
    Please view the 3D Vision Surround system requirements for a full list of supported products.
    Please note that in the first Beta v258.69 driver for 3D Vision Surround, we do not recommend running GeForce GTX 295 Quad SLI because there are bugs in the driver which may result in system instability. We will be providing a future driver update to support this configuration.

    Can I use HDMI connectors to run 3D Vision Surround?
    3D Vision-Ready LCDs require dual-link DVI connectors and will not work with HDMI connectors. However, you can use HDMI connectors with 3D Vision Projectors that support HDMI input.
    Note: 3D DLP HDTVs do use HDMI connectors, but 3D Vision Surround does not support using 3D DLP TVs.

    What resolutions does Surround support?
    Surround requires three displays to operate. Surround resolutions are calculated by arranging your monitors in portrait or landscape mode and then multiplying the horizontal resolution by three times a single display in that mode (portrait or landscape).
    The following table illustrates some common aspect ratios and resolutions:
    1280x1024
    3840x1024
    3072x1280
    1920x1080
    5760x1080
    3240x1920
    1920x1200
    5760x1200
    3600x1920

    Note: 3D Vision-Ready LCDs do not support portrait mode. However, you can run 3D Vision Surround with 3D projectors in portrait mode.

    Can I use 3D Vision Surround with three displays and setup an Accessory display that is not in 3D?
    At this time, accessory displays are only supported in Surround (2D) configuration.






    CUDA
    CUDA™ is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).
    With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA. Here are a few examples:
    Identify hidden plaque in arteries: Heart attacks are the leading cause of death worldwide. Harvard Engineering, Harvard Medical School and Brigham & Women's Hospital have teamed up to use GPUs to simulate blood flow and identify hidden arterial plaque without invasive imaging techniques or exploratory surgery.
    Analyze air traffic flow: The National Airspace System manages the nationwide coordination of air traffic flow. Computer models help identify new ways to alleviate congestion and keep airplane traffic moving efficiently.
    Using the computational power of GPUs, a team at NASA obtained a large performance gain, reducing analysis time from ten minutes to three seconds.
    Visualize molecules: A molecular simulation called NAMD (nanoscale molecular dynamics) gets a large performance boost with GPUs. The speed-up is a result of the parallel architecture of GPUs, which enables NAMD developers to port compute-intensive portions of the application to the GPU using the CUDA Toolkit.

    Widely Used By Researchers
    Since its introduction in 2006, CUDA has been widely deployed through thousands of applications and published research papers, and supported by an installed base of over 500 million CUDA-enabled GPUs in notebooks, workstations, compute clusters and supercomputers.

    How to get started
    Software developers, scientists and researchers can add support for GPU acceleration in their own applications using one of three simple approaches:
    Drop in a GPU-accelerated library to replace or augment CPU-only libraries such as MKL BLAS, IPP, FFTW and other widely-used libraries
    Automatically parallelize loops in Fortran or C code using OpenACC directives for accelerators
    Develop custom parallel algorithms and libraries using a familiar programming language such as C, C++, C#, Fortran, Java, Python, etc.

    What is NVIDIA Tesla™?

    With the world’s first teraflop many-core processor, NVIDIA® Tesla™ computing solutions enable the necessary transition to energy efficient parallel computing power. With thousands of CUDA cores per processor , Tesla scales to solve the world’s most important computing challenges—quickly and accurately.

    What is OpenACC?
    OpenACC is an open industry standard for compiler directives or hints which can be inserted in code written in C or Fortran enabling the compiler to generate code which would run in parallel on multi-CPU and GPU accelerated system. OpenACC directives are easy and powerful way to leverage the power of GPU Computing while keeping your code compatible for non-accelerated CPU only systems. Learn more at https://developer.nvidia.com/openacc.

    What kind of performance increase can I expect using GPU Computing over CPU-only code?
    This depends on how well the problem maps onto the architecture. For data parallel applications, accelerations of more than two orders of mangitude have been seen. You can browse research, developer, applications and partners on our CUDA In Action Page


    What operating systems does CUDA support?

    CUDA supports Windows, Linux and Mac OS. For full list see the latest CUDA Toolkit Release Notes.The latest version is available at http://docs.nvidia.com

    Which GPUs support running CUDA-accelerated applications?
    CUDA is a standard feature in all NVIDIA GeForce, Quadro, and Tesla GPUs as well as NVIDIA GRID solutions. A full list can be found on the CUDA GPUs Page.

    What is the "compute capability"?
    The compute capability of a GPU determines its general specifications and available features. For a details, see the Compute Capabilities section in the CUDA C Programming Guide.

    Where can I find a good introduction to parallel programming?
    There are several university courses online, technical webinars, article series and also several excellent books on parallel computing. These can be found on our CUDA Education Page.

    Hardware and Architecture
    Will I have to re-write my CUDA Kernels when the next new GPU architecture is released?
    No. CUDA C/C++ provides an abstraction; it’s a means for you to express how you want your program to execute. The compiler generates PTX code which is also not hardware specific. At runtime the PTX is compiled for a specific target GPU - this is the responsibility of the driver which is updated every time a new GPU is released. It is possible that changes in the number of registers or size of shared memory may open up the opportunity for further optimization but thats optional. So write your code now, and enjoy it running on future GPU's

    Does CUDA support multiple graphics cards in one system?
    Yes. Applications can distribute work across multiple GPUs. This is not done automatically, however, so the application has complete control. See the "multiGPU" example in the GPU Computing SDK for an example of programming multiple GPUs.













    Nvidia Game Stream
    [​IMG]
    PC GAMING MADE PORTABLE WITH NVIDIA GAMESTREAM™ TECHNOLOGY.
    NVIDIA GameStream harnesses the power of the most advanced GeForce® GTX™ graphics cards or GRID cloud Beta and exclusive game-speed streaming technologies to bring low-latency PC gaming experience to your SHIELD portable.

    With streaming support for over 100 of the hottest PC titles at up to 1080p and 60 frames per second, SHIELD offers a truly unique handheld gaming experience.

    NEW: Remotely access your PC to play your games away from your home.*
    Play your favorite PC games on your HDTV at up to 1080p at 60 FPS using a wireless Bluetooth controller with SHIELD Console Mode.
    NEW: Stream games like World of Warcraft, League of Legends, and DOTA 2 to your HDTV using Wi-Fi and play with full Bluetooth keyboard and mouse support.
    Download GeForce Experience to see if your PC is ready for.


    How GAMESTREAM Works
    NVIDIA uses the H.264 encoder built into GeForce GTX 650 or higher desktop GPUs and GeForce GTX Kepler and Maxwell notebooks, along with efficient wireless streaming software protocol integrated into GeForce Experience, to stream games from the PC to SHIELD over the user's home Wi-Fi network with ultra-low latency. Gamers then use SHIELD as the controller and display for their favorite PC games, as well as for Steam Big Picture.
    In addition to streaming the game, NVIDIA also configures PC games for streaming using GeForce Experience to deliver a seamless out of the box experience. There are three key activities involved here:

    Generating optimal game settings for streaming games from the PC to SHIELD
    We use our GeForce Experience servers to determine the best quality settings based on the user's CPU and GPU, and target higher frame rates than 'normal' optimal settings to ensure the lowest latency gaming experience. These settings are automatically applied when the game is launched so gamers don't have to worry about configuring these settings themselves.

    Enabling controller support in games
    This avoids gamers having to manually configure controller support in the game – it 'just works' out of the box.

    Optimizing the game launch process
    This is important so that gamers can get into the game as quickly and seamlessly as possible, without hitting launchers or other 2 foot UI interactions that can be difficult to interface with a controller.

    Steam Big Picture
    Big Picture shows up as a selection in the list of SHIELD-optimized games. Launching it gives you access to your Steam games – both supported and unsupported – plus the Steam Store and all the Steam community features. Supported games are recommended for the best, optimized streaming experience – the latest list of supported games can be found on SHIELD.nvidia.com starting at launch.
    Unsupported games may work if they have native controller support, but will not be optimized for streaming and may have other streaming compatibility issues.


    System Requirements for PC Game Streaming:
    > GPU:
    - Desktop: GeForce GTX 650 or higher GPU, or
    - Notebook (Beta): GeForce GTX 800M, GTX 700M and select Kepler-based GTX 600M GPUs

    Whilst it's not for gamers*, CUDA is a very powerful development tool available for those using Nvidia GPUs.

    * Remember, though, that this is not the "Gaming Graphics Card Forum" and there will be people who use their GPUs for other tasks!

    Good idea for a thread, so long it stays on track.
    Action for AMD GPU encoding but comes at a price tag.

    Action offers the same features as shadow play with a great low performance hit, by using amdapp for gpu encoding on the fly.

    Might be worth putting in brackets something like 'limited use on other non nvidia/AMD systems' too.

    For example TressFX works on everything, as does Physx, though one may not work AS well as it would on the hardware its designed for etc...

    Just so someone doesn't look at it and think 'bugger, that feature only works on NV/AMD cards' when it may not be true

    I don't think Physx works at all now on AMD cards does it? I think there was a hack/workaround that was patched out.

    Some games let you run it on cpu, I played batman and metro ll with Physx on. While I wouldn't get the frame rate a nvidia gpu would get it sure was very playable.

    Metro's hardware accelerated PhysX.
    Most PhysX isn't.
