im currently playing bf1942 with desert combat installed on my imac. Its weird at begining everything worked perfectly but now with my reso. of 1680#1050 it lags hardcore. It says on box recommended: G4 867mhz, 256 of ram and radeon 7500. My iMac is way over those specs. Even when i turn reso to lowest it lags... i cant understand why.. but it does lag less online please helppp?????
