First-Person 3D Shooters
Call of Duty
This game has no complex pixel shaders and is overall simple, so the RADEON X700 XT has nowhere to show its shader-processing skills at and delivers the performance of the RADEON 9800 XT, losing to the GeForce 6600 GT.
It’s different with full-screen antialiasing and anisotropic filtering: the GeForce 6600 GT does the jaggies-smoothing less efficiently than the RADEON X700 XT. Curiously enough, the latter is not at all hindered by its narrow 128-bit memory bus, even in 1600x1200 resolution.
