IL-2 Sturmovik: Forgotten Battles
IL-2 Sturmovik: FB - OpenGL

Notes
Performance of both XT cards gained slightly in IL-2 Sturmovik: Forgotten Battles at 800x600x32, but with the increase of only 1 fps, it still falls within the margin of error and wouldn’t be noticed by the end user. With their demanding physics models, sims tend to stress platform performance more than graphics, so they aren’t the best graphics test, but useful nonetheless.
