Hello, Lately my macbook (running Windows 70 has had performance issues running games. It used to be able to run games like TF2, minecraft and CSS with 50+Fps but lately its been struggling to even get playable FPS in TF2 and minecraft i have tried cleaning out dust, defragging the disk and turning the fans to max. The combination of these have made it better but its still not running as good as it used to be. Anybody got any tips on fixing this? Im contemplating re-installing windows 7 and just re-downloading everything but i doubt that will help.
