Crysis
Whilst selling an inordinate amount of copies, Crysis uses an engine that doesn't scale well with cards based on the same generation. There is little perceivable performance benefit from the ZALMAN-equipped Sapphire over its reference brethren. We'll have to wait for the Warhead evolution before proper scaling is implemented.
Tellingly, all cards score below 30fps (average) at the 1,920x1,200, and this is without any additional antialiasing or anisotropic filtering.
