After reading some news about Starcarft 2's problems with graphic cards, I have made a simple test with contruct . This articles point that the bug is the unlimited frame rate mode. I used Piriform Speccy to see the graphic card's temperature with my game.
Without running game: 60 �C
Running at 60 FPS, framerate mode V-Synced: 61 �C
Running at 546 FPS, framerate mode Unlimited: 80 �C
