Okay so i recently got CoD4 for mac. While i am playing the game i get bad dips to about 15 fps and the game gets very choppy. I am running the game on pretty low settings (no shadows,AA) I am using a Unibody MBP 2.4ghz,4GB of DDR3. Shouldn't the 9600GT be able to handle CoD4? Or am i just expecting too much? And yes i do have the 9600GT enabled. Any help would be appreciated! Thanks.
