According to this site, Doom 3 shipped with a Nvidia friendly shader activated... there is an ATI one hidden in the pak files, that does the opposite (makes NVidia look like a elephant in molasses)...

the above link walks you thro the process...

edit - it works... if its any indication, I get solid performance at 1024x678 now, rather than the just 'playable' at 800x600 I had before :)

of course you could just buy an nVidia card since ATI are made of lose...

doom3 may have been more optimised for nvidia (besides them currently having better GL performance) because ATi were apparently the source of the leak. carmack also said that the GF6 is THE card to play D3 on. this is the second optimisation for ATi cards that give it a significant kick, i hope id put them in the first patch and make them official. also so we aren't using modified .pk4 files

i doubt they'll build it into the patch, because just like the default shader munts ATI cards, the alternate one totally devastates Nvidia GPU's... looks like its the modified files all the way (even tho it is only a 2kb download)

there's already separate code paths for different GPUs. ARB1, ARB2, NV10, and NV20. nvidia need the coding hax again
