DOOM 3 & DX9 [Sep 17, 2003, 7:08 pm ET] – Share – Viewing Comments
With all the discussion lately about how Half-Life 2 will run on ATI hardware
compared with NVIDIA accelerators, BonusWeb.cz
shot off an email to id Software's John Carmack to ask how DOOM 3 and other
games are likely to be impacted by the difference between the two graphics
platforms running DirectX 9. Here's how he responded:
Unfortunately, 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.
Imagine the performance the Radeons would achieve if Carmack wasn't still pissed with ATI for leaking the D3 alpha and he was optimising the game for Radeons as well as GFs?
Carmack? Isn't it time you grew up and wrote the game for both sets of card owners? People aren't going to buy a $500 GF card, just to play your game, and to the detriment of ATI.
If all other games play faster with an ATI card then a lot of players may just forgo your game and enjoy what is playable with what they have or what will play with a lot of games. Remember that D3's only real competition in the near future will be HL2, and Valve have already stated that nVidia cards are going to suck by comparison.
