IL-2 Sturmovik: Forgotten Battles
Flight sims are processor-dependant games by their very nature. They require processing of a complex physical flight model, which is performed by the CPU. So we only see some difference in the results of the cards in high resolutions where the speed of the graphics card, rather than that of the CPU, is more important.
Strangely enough, the GeForce 6800 Ultra lost its first position to the RADEON 9800 XT starting from 1280x1024 resolution in the eye-candy mode. What’s the reason? It seems like the driver is again to bear the blame.
