Since our last articles on Windows 7 the ATI Radeon 5800/5700 series of graphics cards have launched and two games are now available which have DirectX 11 features. Today we take a look at performance and image quality differences between DirectX 10.0 /10.1 and DirectX 11 when running Windows 7 on ATIs latest hardware. The article also includes the worlds first detailed look at S.T.A.L.K.E.R: Call of Pripyat running in DirectX 11 mode.

I don't notice major differences between DX10.1 and DX11 for both titles.

I think the lighting is subtley better - soft shadowing on the chair etc.

interesting article, even in the early days it is showing some potential.

Well, these are the first games to utilize it and DX11 was probably a bit of an afterthought (especially on BattleForge), so it's not the full potential of the new API.

Still, BattleForge has demonstrated how it allows for same (or even marginally better) visual results with a significant boost in performance, while STALKER probably has the nicest, most natural looking shadows I have seen in a computer game so far. I'm not completely sold on how they used tessellation, though, the gas-mask looks good, but I'm not sure about those "jaggies" that appeared on the abdomen of the character's uniform when DX11 was enabled.

Battleforge wasn't meant to go realistic in terms of visuals, they're just using directcompute as a way to get performance gains.

Nice Review, Stu.
Nice breadkown and all, I'm already on 7 so time for a 5870 ... when I can afford one.... so where's the contest already? :P

most intially things that show off the differences don't usually take full advantage of it.....

I quite agree with you Judas, Most games that weren't fully built to incorporate the features do not take advantage, because the engine was built to handle Dx 9 or 10, I think AVP is the game that looks like it's built to handle DX 11. I hope it lives to its hype.

This DirectCompute stuff seems interesting, I know it's been around a while. But now looks like it's taking off in both Red and green camps.

Well i just keep looking at some of the things that people have managed to get working with DX9 even though those specific features were designed to work with dx10 only.. which obviously suggest that the engine or game or whatever isn't making proper use of dx 10..

same thing could be said for dx10.1 and dx11

however the Assassins Creed game kinda makes this seem a little interesting that a dx10 platformer that when NOT patched takes proper advantage of DX10.1 producing noticeable results when running under dx10.1 circumstances

So it's very obvious when something that actually takes advantage of even some of the other features that aren't possible on previous version....

Personally i'm waiting to see hardware realtime Ray Tracing in action at it's fullest capacity..... no more "fake" reflections and shadows.
