Im having the same problem. Seems to be working better if i set the graphics to laptop and the lowest... But still crashes sometimes just less frequently .

I have 2x SLI GTX 670 so i should be able to run max setting without any problems. But every time i run the game. It crashes to desktop within 3min of logging in.

Its been like this for a week now and i fear i wont resubb since i cant really play the game .
