In Doom, the 2900XT was again only behind the 8800 GTX in all settings and is widely outperforming the 8800 GTS at resolutions of 1600x1200 and above. With AA/AF enabled the 2900 XT is significantly faster than the 8800GTS across the board, with the performance gap increasing as the resolution goes up. Actually at the crushing 2048x1536 resolution the HD 2900 XT is 21% faster than the 8800 GTS - clearly a storybook win for ATI here. Quake 4 was another story, as we determined that our benchmarking platform tops out in the mid 80s FPS. While you can ignore the non AA/AF scores, the AA/AF on scores are much more meaningful. Here the 2900XT and 8800 GTS are neck and neck with the lead slightly in the favor of the 8800 GTS. Remember, the 8800 GTS performance is around where ATI wants its card.
