Call of Duty 2

The game engine built by Infinity Ward supports dynamic lighting and shadows, effects, normal maps, advanced smoke and other shader-based effects. The 16 pixel processors of the PowerColor X800 GTO 16 cope well enough with this abundance of shaders, although the frame rate is hardly comfortable even in 1024x768. The card wins the “pure speed” mode of the test, but as soon as we enabled FSAA and anisotropic filtering, it gives in and rolls back almost to the very last position. We don’t know how to explain this. The problem might be similar to what we have already seen in Serious Sam 2, when the ATI Catalyst driver cannot distribute the video memory resources efficiently.

Doom 3

It’s like in The Chronicles of Riddick and the reasons are the same: the game engine uses the OpenGL API and renders dynamic stencil shadows GeForce 6/7 cards are efficient with, being capable of processing a double number of Z values per clock cycle. Intensive use of the Z-buffer is the key point of this shadows-rendering method and the UltraShadow II technology all modern GeForce cards support comes in very handy here.

The performance of the PowerColor X800 GTO 16 is sufficient for 1024x768 resolution only. You’ll have to reduce the level of detail to play comfortably in higher resolutions.
