Colin McRae Rally 2005

This auto sim makes an intensive use of pixel shaders, and ATI’s RADEON X800 cards run it faster than NVIDIA’s GeForce6 ones do. Both RADEON X800 XL models are far ahead of the GeForce 6800 Ultra, although the gap becomes somewhat narrower in 1600x1200.

The new RADEON X800 XL doesn’t seem to have any speed bonus from its large memory when 4x FSAA and 16x aniso-filtering are enabled.

Here, we have the same thing in resolutions above 1024x768 as in Il-2: Sturmovik. That is, the RADEON X800 XL 512MB is behind the 256MB version of itself, although the gap is only 2fps at most.
