Serious Sam 2

The GeForce 7900 GT is beaten by the Radeon X1800 XT despite its 24 TMUs and the fact that this 3D shooter uses shaders with multiple texture lookups (from 4 to 8 per shader). Why? Serious Sam 2 just needs 512 megabytes of graphics memory at its maximum graphics quality settings. Otherwise its speed gets much lower.

The GeForce 7900 GT has the lowest minimum speed among all the participating cards even in the lowest resolution. The game may slow down to 1-5fps on this card whereas the GeForce 7800 GTX, a card with similar characteristics, ensures a min speed of 12-26fps depending on the display resolution. It must be some problem in Nvidia’s driver because we reran this test to get the same picture of performance. We observed no image artifacts in this game, by the way.

The GeForce 7800 GTX 512 and Radeon X1800 XT are the only single-GPU solutions in this test session that allow playing Serious Sam 2 with turned-on 4x FSAA, but you are limited to 1024x768 resolution. The Radeon X1800 XT is just a little slower than the SLI configuration with two GeForce 7900 GT.

The performance of the tested multi-GPU solutions in the extreme antialiasing modes is too low for comfortable play.
