I have a base model with 8 gigs of ram and I only play Source based games like Counter-Strike Source. If I am on bootcamp I get 60fps, but if I am on OSX I get 25-30fps using the native port. If I run windows on parallels I get 35-40fps. My question is why the osx version get such low fps even the virtualized copy runs better! Is this true for other games?
