I recently purchased a Macbook Pro with a 512mb video card. I play this game, Medal of Honor, but I only get around 60 frames per second and it;s also kind of jumpy. I don't understand why I get so little when I have such a good video card. I tried lowering and increasing my graphics in the game, and the FPS stays pretty much the same wether the graphics are high or low. I also tried entering a command to increase the FPS limit, but it still stays the same... I just don't get it.
