ATI's Radeon X1900 XT has a clear 4-6 FPS advantage in Call of Duty 2, even over the GeForce 7900 GTX. Its lead is consistent throughout all resolutions and AA/AF levels.
Doom 3
Doom 3 performance starts out with what seems to be a competition between the 7900 GTX/7800 GTX 512 and X1900 XT/7800 GTX. The 7900 GTX has an ever-so-slight lead in the higher non-AA/non-AF resolutions, but that lead is reduced to virtually nothing once we enable AA/AF. The X1900 XT makes a bit of a come-back with the AA/AF tests because of what seems to be a slightly more efficient AA/AF implementation than what the NVIDIA cards possess.
