Mass Effect
With antialiasing, there’s an apparent limit of 60 frames per second (despite disabling vertical synchronization and the Unreal Engine 3-specific smooth frame rate, the limitation may be at the level of the processor). It’s interesting to note that testing with antialiasing enabled established a stepped ranking of all the cards at 1680x1050, with the same hierarchy as at 1920x1200. Only the GT200s could hit 60 fps; the 4850 had trouble staying ahead of the Radeon HD 3870 here, but at least it could play with antialiasing enabled, unlike its older brother. But it still wasn’t able to catch the 9800 GTX +, while remaining up to 26% behind (at 1920x1200 + filters), and 35% behind the Radeon HD 3870 X2 at 2560x1600.
