Star Wars: Knights of the Old Republic

There are no complex DirectX 9 pixel shaders here, on which the RADEON X800 Pro would show the advantages of its speedy architecture, and the GeForce 6800 GT wins the test. Extreme overclocking helps the PowerColor to outperform the rival but the overclocked GeForce 6800 GT is still beyond its reach.

Prince of Persia: Sands of Time

It’s all the same in Prince of Persia: a high fill rate and a fast execution of simple pixel shaders matter much. As a result, the PowerColor RADEON X800 Pro cannot compete with the GeForce 6800 from Leadtek even during extreme overclocking.

IL-2 Sturmovik: Aces

The RADEON X800 Pro loses both modes of this test. The loss in the hard mode is rather strange, since the new chips from ATI are usually more efficient at doing FSAA and AF than the new GPUs from NVIDIA.

Lock On

The graphics cards are equals in Lock On: the Leadtek is ahead in the pure speed mode, but the PowerColor is better at giving us the “eye candies”.

Homeworld 2

Homeworld 2 doesn’t use complex pixel shaders, and the NVIDIA GeForce 6800 GT is faster here. At overclocking, both cards produce the same fps rates since they are limited by the performance of the central processor. Regrettably, we couldn’t run Homeworld 2 in the “hardest” mode – NVIDIA GeForce 6800 GT cannot enable forced anisotropic filtering in this game.
