Macbook Pro Retina 15'/Sudden drop in graphics perfomance
Hi, I purchased the base model of the Macbook Pro Retina 15' display 2 weeks ago and recently installed Windows 7 via bootcamp just so I could play a couple of games which were not supported on OS X. Everything was going well until 3 days ago when I turned my mac on, logged into windows, booted up Bordelands 2 and noticed a massive drop in frame rates causing the game to be very laggy. At first I thought it was a problem with the game but then I had the same problem with Skyrim. I then reinstalled Windows 7 and the problem persisted. So I did a CineBench test on OS X Mountain Lion and got 14.7 fps on the OpenGL test which is more than half of what other people get with the same model Macbook Pro. So now I'm stuck on how to fix this, I'm not sure whether this is a software or a hardware problem and if there might be a quick fix that I can do or if I have to take it to an apple store to have it replaced. I would appreciate any help, thanks.
