I got my macbook pro about 2 weeks ago and decided last week to test out a few games (Age of empires 3, World of Warcraft). I have been playing fine with no lag or anything, but today, when I fired up WoW, there was massive lag. I then tried the same with AoE 3 and still the same thing: massive lag. Considering I have only had the laptop for TWO WEEKS I don't think it's a dead GPU, so can anyone help me as to what it might be please? I can provide any other information that might be helpful for this problem. Thank you.
