THIS IS WHY A 680 IS REQUIRED!!

Hi there


I spent the last week at Monte Carlo at NVIDIA conference with them showcasing latest technologies, one of the things that impressed me the most was watching the upcoming EPIC GAMES Samaritan demo and I was watching the real deal, not a video clip, to put it bluntly, mind blowing.

This game previously took 3x 580 to run at high-res and details. Yet now a single 680 can run this game at acceptable performance levels. This game is specifically designed for PC, it won't even run on a console, so its great to see game developers moving in this direction.


The Youtube video is terrible quality, to experience the quality download a high-quality video clip from here:-

Unreal Engine 3 takes game engine graphics to the next level with “Samaritan,” a real-time demo revealed at the 2011 Game Developers Conference.

Now supporting DirectX 11, UE3 utilizes DirectX features such as tessellation and displacement, geometry shaders, multisampled textures and Shader Model 5.

High-end rendering features include:
•Image-based reflections that allow surfaces of any shape to reflect an approximate version of scenes, with varying glossiness across surfaces, anisotropic HDR highlights and anti-aliasing;
•Subsurface scattering (SSS) that simulates the light that scatters inside semi-translucent materials, which makes character skin come alive;
•Anti-aliased masked materials that super sample the edges of masked and alpha-tested materials, resulting in highly realistic hair;
•Deferred rendering with MSAA support;
•Bokeh depth of field providing close to film-quality DOF, with artist-controllable Bokeh; and
•High-quality dynamic shadows from many lights on the environment.

Epic also worked with NVIDIA to implement APEX physics technology, which is illustrated by dynamic clothing movement in “Samaritan.” Other APEX features available now include turbulence and real-time destructibility.

All these cutting-edge features are now available in UDK.
 
A more efficient form of AA was used with the GTX680 cards,ie,the settings were not the same with the GTX580 cards. On top of this you need to consider the potential issues with SLI scaling in the demo and the fact there was plenty of time to optimise the demo for the GTX680.

What I would like to see is the GTX680 against a GTX580 3GB using exactly the same settings and the same level of optimisation. The GTX680 should be faster but the might be able to run it but at lower framerates.

It does look fantastic!

Now I just need someone to buy my 7970 so I can get playing with a pair of 680's :D
 
I would imagine in the flesh, so to speak, the demo looks fantastics, shame they haven't uploaded a 1080 version to you tube so even if you set it to 1080 on youtube it still looks a bit gash
 
Any games featuring this tech?

not currently, possibly Lost Plant 3 as that's the only UE3 engine game that is announced but still early enough in development that it could be added

epic have previoulsy said that UE4 won't be released to developers until sony and microsoft give them details on what the next gen of consoles will be

this tech demo was to show them what they could offer as an engine if they put enough hardware in to the consoles to run it
 
I still think they should release the demo. It probably really wouldn't require a lot of effort.
 
if all of this is about to happen, it makes you wonder why Nvidia are botherring trying to sell lower spec cards like the 670, 660 whatever

Along the lines of what I was thinking, so contrary to the thread title... none of us needs a 680 :D

It'd be nice to see a game come along that actually needs one below 2560 res.

This. The AA used in the 680 demo was less intensive. In addition, the engine had many months of optimisation done on it. Therefore, this tech demo is not a credible example of the 680's supposed superiority over 3 580s.
 
Is it really a case that CPUs are so underpowered that it requires a £400 card just to play such games at 'acceptable levels'? If I spend £400+ on a GPU then I want it to run everything on max.
 
I could put that game on a single monitor on a 6850, turn shadows and aa down and depth of field off, run it side by side with a 690 with those things maxed out, show it to a random person in the street and they wouldn't see £700 worth of difference.
 
It's classic Nvidia PR. 3x 580's are massively more powerful than a 680!

Of course they are, the 3x 580 were on previous gen drivers without FXAA. So with the new drivers, FXAA and game code being more optimised for 680, what was previously taking 3 cards, is now capable on one.

So with like for like drivers, of course 3x 580 would be quicker, but at the same time it is great NVIDIA are improving their drivers and making new features available on older generation too. :)
