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.
an article on the new nvidia drivers and how they don't do muchOn the contrary, look at the PS2.0 shader performance in the 3DMark03 bench. 25% increase in performance there, which is where it's going to matter.
I'll add this, has anyone thought that maybe the FX line's poor performance in default DX9 is because it runs FP32 by default (instead of FP24 on the Radeons)? So it could be Nvidia's attempt at pushing higher detail turning around to bite them in the ass. I wonder how the cards would match up against each other if the FX ran FP24, or the Radeons ran FP32.
