I recently got a brand new macbook pro 15" and upon installing and playing Call Of Duty 4 I find myself getting terrible fps. I know the mac version isn't well optimized but it should still be playable? right? especially since I upgraded to the 15" over the 13" in hope of better gaming performance. COD4 recommends me a ridiculously low resolution and some pretty low graphics settings, but even using those result in poor performance. I honestly expected better than this. How is your performance in the mac COD4? Could I have a faulty 330m? Some other games (portal for instance) run pretty well but when I turn my character round quickly the image sometimes distorts a bit and there is horizontal lines of distortion if that makes sense.
