F1 Challenge 99-2002
The performance of all graphics cards proved to be limited by the speed of the central processing unit in the Formula 1 simulator. In this case, which is remarkable, the results of GPUs from NVIDIA seem to be higher – either NVIDIA’s ForceWare driver allocates less CPU resources, or the game itself runs a bit different code-paths on hardware from ATI and NVIDIA.
Only in high-resolutions with FSAA and anisotropic filtering modes enabled graphics cards are no longer limited by the CPU. The GeForce 6800 Ultra is the winner, but the gap between it and ATI’s RADEON X800 XT is negligible.
