Doom III - Medium Quality 4xFSAA
When 4xFSAA is enabled, not a single card can hold a candle to the FX 5900 Ultra. The FX 5800 Ultra is roughly on a level with the ATI cards. An interesting note on the side: more RAM doesn't seem to yield any performance benefits in DOOM III, as the Radeon 9800 PRO 256 MB shows.
Conclusion, DOOM III
As was to be expected, DOOM III will only be playable at acceptable framerates on the latest generation of graphics cards. While older cards will naturally also be able to run the game, the level of detail will be greatly reduced. When it comes to speed, NVIDIA's GeForceFX 5900 Ultra is currently unbeatable, at least in 4xFSAA. In the remainder of the tests, its direct predecessor, the FX 5800 Ultra, is also its closest competitor. The Radeon 9800 PRO, on the other hand, can only win the tests at high detail levels in low resolutions.
In conclusion, we would like express our thanks to John Carmack and the team at id Software for making this test possible.
