DOOM 3 & DX9

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.

right folks,first of all i think you should all chill out getting so speculative over games that aren't even on the market yet. There not out yet so we dont know how they will perform exactly except that HL2 is tuned for ATI and D3 is tuned for FX.

Theres some very good techy jargon in some of these posts,dont get me wrong you know your stuff but i also work in the hardware market.I work in the testing/returns dept in a pc hardware retailer (not some shitty company like pc world etc....I wont say who coz im not giving free adverts to my employer!) and so have to test new products before they come out (through visits by manufacturer reps and such),all current products and also see what things fail on a regular basis and so see a good view on products.I feel sorry for any of you with a gigabyte radeon 9700 pro - nice card, shame about that fan.

Anyway, some peoples ranting about both companies makes me wonder what planet your on, im slightly disappointed by my 128m gainward 5900 at the moment - probabably the same as most owners of a top end FX card at the moment. Only slightly though, because despite all the talk of 'cheats' (which ARE also good optimizations - check the sky in UT2K with the 50s compared to a radeon) the card still kicks ass even if it doesnt live up to expectation.

Were all getting shafted by Valve/ATI and ID/NVIDIA only because there will be clear hardware borders, theres nothing we can do about it....but at least well be able to play 1 of the 2 very well. And anyway if you have a 9800 or a 5900 and a nice system,what are u moaning about? You have a kick ass system and youll have probably got a new card by the time these games come out judging by all the put-backs!Stop crying
