The Elder Scrolls IV: Oblivion
We didn’t test this game with enabled FSAA, because HDR support would be disabled in this case.
In the tunnels of Imperial City GeForce 7900 quad SLI outperforms Radeon X1900 XT CrossFire in 1280x1024 already, and as the resolution grows the gap increases reaching its maximum – 50% - in the maximum supported resolution of 2560x1600. In this case you can still enjoy the gameplay, as GeForce 7900 quad SLI fps rate doesn’t ever drop below 30fps.
The open spaces of the Cyrodiil push the graphics subsystem to the limits, however GeForce 7900 quad SLI manages to provide quite acceptable level of performance. Check out the dynamics of the performance change with the growth of the screen resolution: the gaming performance of the quad SLI system decreases slower than that of the Radeon X1900 XT CrossFire system. As we move from 1280x1024 to 2560x1600, GeForce 7900 quad SLI performance gets only 20%-22% lower, while the performance of a Radeon X1900 XT CrossFire based platform drops by the good 60%.
