Only slightly relevant -- but I noticed the last support request I filed with RH recently was found to be due to a bug in the kernel that was actually fixed in 3.0, but hadn't been back-ported. Because of things like this I just figured the majority of libs and the kernel worked like that in RHEL... Basically that they'd only back-port security fixes, major bugs, perhaps major performance enhancements, or if you report them - smaller bugs that affect their customers. e.g. I wouldn't see them backporting fixes to the graphics stack unless their business clients are really using the open source stack.
dx conversations cost much speed. opengl games run with nearly fullspeed via wine.
Besides... Valve has always been AMD and ATI fans. They're talking with AMD and nVidia will be nowhere near the Steambox, just like the Xbox360.
Source works fine on AMD hardware on both Windows, Wine and the Xbox360, none of which have any nVidia related crap anywhere near it.
So to get ontopic: Valve is awesome as usual! (and late as usual)
Back then I had a 5950 Ultra, my friend had a 9800 PRO. My card was faster and beat the 9800 PRO by almost 10FPS in Doom 3, but ATI's hardware performed the same as mine in HL2. Valve took their time optimizing for ATI's architecture and continues to do so.
Also as far as AMD vs Nvidia goes, I will never ever even remotely consider buying any system with a GPU from AMD after I experienced this. Hardware malfunction error BSOD != my idea of fun.
Yes, Valve is awesome.

And the answer was:No doubt you heard about GeForce FX fiasco in Half-Life 2. In your opinion, are these results representative for future DX9 games (including Doom III) or is it just a special case of HL2 code preferring ATI features, as NVIDIA suggests?
Edit: And Newell opinion http://techreport.com/articles.x/5636/1Unfortunately, it will probably be representative of most DX9 games. Doom has a custom back end that uses the lower precisions on the GF-FX, but when you run it with standard fragment programs just like ATI, it is a lot slower. The precision doesn't really matter to Doom, but that won't be a reasonable option in future games designed around DX9 level hardware as a minimum spec.
