None of the cards in this review has any problems with this test. The lowest average frame rate is provided by the GeForce 7900 GT and it is 94.5fps in 1600x1200.
The performance of the flagship products from ATI and Nvidia is limited by the speed of the central processor, yet we can see that the non-overclocked PowerColor X1900 XT is a little slower than the GeForce 7900 GTX in high resolutions.
Serious Sam 2
None of the existing graphics cards can deliver an acceptable frame rate in Serious Sam 2 in resolutions above 1024x768 if you turn on full-screen antialiasing and anisotropic filtering and use the highest graphics quality settings.
Overclocking doesn’t help the PowerColor X1900 XT much here, giving it a bonus 3-5fps. The reason is that the developers of the game stuffed it with shaders with multiple texture lookups.
The best results in this test are turned in by the GeForce 7900 GTX and GeForce 7800 GTX 512, yet they are not very much better than the others. And there is still no performance reserve as the game speed may bottom out to below 15fps in the most complex scenes.
