I installed a copy of Windows Vista on my 15in Macbook Pro. I did this in order to play Pro Evolution Soccer 2009 and some other games on my laptop. The machine is more than capable of running the game and I've read forum posts that had said that it works perfectly fine through boot camp. I installed the game and was playing it just fine for about 1-2 months until one day the game began to lag really bad and the sound also disappeared. My Mac partition is absolutely fine. Please help!
