Essex innit!
Mostly we have discussed the raw power of the GTX 1080 and not seen much mention of Ansel (which I think is a really cool idea) and

As a gamer, I love to take beautiful screenshots, but today’s tools are incredibly limited. Getting the perfect shot requires hitting the Print Screen key rapidly, all while constrained to the in-game view and monitor resolution. The lack of precision and control makes it nearly impossible to capture the shot I want.

NVIDIA is changing this with the introduction of Ansel, a powerful, easy-to-use game capture tool built in cooperation with leading game developers.

Ansel lets you freeze time. You can compose your shots from any angle and adjust the image with post-process filters. You can capture at unbelievable resolutions, grab EXR images for full-spectrum color capture, and share your screenshots in 360° panoramas via your smartphone, PC or VR headset.

Ansel-technology

Here’s how Ansel can help you take amazing screenshots:

  • Free Camera — Roll, zoom and reposition. Go wherever you want to create the perfect photo. Ansel instantly overcomes the limitations of traditional game capture, allowing you to frame the perfect shot.
  • Super Resolution — Once you’ve positioned and framed your shot, Ansel allows you to capture screenshots at up to 4.5 gigapixel resolution, or 32x higher than your screen resolution. Using your NVIDIA GeForce GTX GPU, Ansel can render and save these screenshots in just seconds. The result: images that you can downsample to lower resolutions for wall prints, posters or super-high-quality desktop wallpapers.
  • Post-Process Filters — So you can tweak the look, feel and mood of your screenshot before saving, Ansel includes brightness, vignette, sketch, color enhancer, field of view and many other special effects options. It lets you create and share your own special FX filters, as enthusiasts do now for ReShade and other post-process applications.
  • OpenEXR Capture — If you’ve got a high-dynamic range TV or monitor, you can export Ansel screenshots in the OpenEXR format, enabling you to view high-dynamic range, super-resolution screenshots at the highest possible fidelity. Or you can export in OpenEXR to work with the image in editing tools like Adobe Photoshop to further adjust the look of your screen captures.
  • 360-degree Capture — With Ansel you can also capture 360° panoramic screenshots. It automatically stitches the 360° panorama in mono or stereo so you can view them in Google Cardboard, on your PC or in a VR headset. For Cardboard users, we’ve released the NVIDIA VR Viewer bundled with Ansel 360 Capture screenshots that you can view today. Download the app and check it out!

And for the bit that bugged me the most when triple screen gaming, they have brought a new tech called Simultaneous Multi-Projection. In a nutshell, those who have gamed on multi monitors will back me up when I say that the side screens were horrible and looked stretched and warped. Not sure of the technical term but we used to refer to it as 'Fisheye' but looks like NVidia have now solved this problem.

Meanwhile, Simultaneous Multi-Projection is a new rendering pipeline for Pascal cards that allows them to render 16 independent "viewpoints" in a single rendering pass. In a regular graphics card, a single viewpoint—i.e. what a user sees on a monitor—is rendered in one pass. That's fine for most applications, but problems occur with multi-monitor setups and VR. In a triple monitor setup where a users curves the monitors, the graphics card can only render a single viewpoint, where it assumes all the monitors are arranged in a straight line, resulting in the images on the left and right monitors looking warped.

So not just a new GPU but some additions to the way rendering is done and I can see many people using Ansel and posting in the High res image thread in the games section :cool: Plus some crazy amount of IQ to boot.
 
This sounds really good. Polaris XT will need to at least as fast as Fury X and be a true overclockers dream to stop me from picking up a 1070 I think :D
 
Ansel looks and sounds pretty good. Something my brother will most certainly love.

The second part. I don't really know what they are talking about as I've never experienced a triple screen set up.

Quite looking forward to all this new tech!
 
This is make or break for AMD I fancy, Nvidia got some good tech right there. Being an owner of 390 crossfire and Freesync screen, if AMD don't deliver something very big by the end of the year, then I'll be jumping ship. I'll just move to a 1080ti or equivalent and give up on freesync for the time being. Will be hard a Freesync is so epic, but I'm only interested in raw power....which AMD seem to not be caring for.
 
Ansel wouldn't be for me. I am not very creative :D:D. The multi screen tech sounds good for those who use it. I think Vr might just kill some of the love for Multi screen gaming though.
 
They also have a new tech which helps massively with VR rendering at no IQ cost at all. This is probably where the 2x Titan X performance thing comes from.
 
Ansel is one of those ideas that I think looks really cool, but will end up not being used much after my initial muck around with it.

I'm more interested in the 3d sound solution they've come up with. Hopefully it (or another implementation) will make it into regular games as well as VR. Modern gaming audio is pants.
 
Not sure as a limited gamer I would find any use what so ever with ansel. Screenshot for me are only for showing really weird and silly things that other might not have seen. It's not like I play really obscure games that nobody else has played.

Always wanted to try multi screen. But never have so the problems are not known by me. Fixing them before I try them is great though.

Afaik the entire point of the VR rendering gain was that they do it at an IQ cost. They want to lower the resolution of the outer edges as you aren't looking directly at them so you won't notice it.

http://www.pcgamer.com/nvidia-gtx-1080-1070-features-detailed/

So it's not about no IQ loss, it's directly about reducing resolution to gain frame rate, it's a complete cheat and absolutely reduces IQ.

I find it particularly funny as for years they've banged on about DoF as great and realistic, reduce performance by blurring this area of the screen they think you won't look at. Now they want to reduce res to increase performance because you apparently won't look at the edges of a screen. Reducing the resolution and increasing performance is like eleventy billion times better than adding an effect that reduces IQ but costs performance. But ultimately it's still based around using the mouse for head movement and basis every quality decision based off the fact that you'll never not look exactly at the centre of your screen. How you can have that view while at the same time pushing increased IQ for surround gaming. Hey, we know wider view and higher quality is better, but over here, nope, we'll reduce IQ because you don't look at the sides at all, entirely contrary. The reality is they know full well that good quality all around is the way and this is a way to get more performance, it's not even a terrible idea, but call it what it is. Say straight up that we have this option for full res all over the screen or if you want higher frame rate reduce resolution on outside edges. It should be marketed as a performance boost IF you want it.

Vr Audio, seems based on true audio in that the fundamental part is adding an audio component to textures. IE that brick wall texture has a audio value assigned to it in design so the audio algorithms can decide how sound interacts with it.

Game changer the multi view point for triple monitors and VR.

Running triples you always get the distortion (unless the game caters for it, ie iRacing) and this will be so good for triple players.

The Single Pass Stereo is a godsend for VR users, with increased FPS to help hit the 90FPS needed.

Both of these depend on how it is implemented and whether the game needs coding for it or it works out of the box.
 
Can't say I really care for the screenshot side of stuff, hate it when people apply filters etc. to game screenshots, I much rather just have un-edited RAW screenshots.

I am guessing the part where you can manoeuvre the camera is a bit like the screenshot function we have seen in a few games lately i.e. batman arkham knight, mad max etc.

As for the people with triple monitors, you want to get with the times and join the 21.9 master race ;) :p :D

Yea that's a really nice feature as fps is king in VR although people are saying Maxwell should support this. I would have to see it in action but i did find myself looking forward more than anything with the vive headset on so doubt i would notice any difference in visual quality.

The big questions is

Does the game need to be coded to user ANSEL and Single Pass Stereo or have nVidia found a magic way of making it work out of the box ?
 
I think super wide started making 3 screen gaming lose it's appeal for me. There are some games such as racing titles where you can forgive the partitions between screens but I'll be more than content with a curved 3440x1440 instead of 3 screens. That's where I'm going now anyway. I'm just waiting too see if there's a decent future in AMD and freesync before committing to one, Plus I'd like to see bigger than 34" if poss :).

If they did a curved 40" 3440 x 1440 and manage to give us 120/144hz I'll be content till I die, Unless I live a lot longer than expected and we get Star Trek type holodecks for gaming :D But I won't hold out for that option.

I am sure it is done at driver level and more will be added as they go but purely guessing here.

There's no master race in 21:9...stop fooling yourself mate ;) Plenty of games with no support, new games without it, and others where you have to do some sort of tom foolery to get it working ;)
 
21:9? you need to get some 32:9 curved screen action, is pretty much double monitors but without the annoying bezel and gap in between. :D
