I seem to be having the problem everyone else is having. I've got a dxdiag if that'll help make the diagnosis haha. Some examples of when the crashes occured are: final form of the final boss (yeah...) and while i was saving the game. Oh and my laptop is widescreen, if that means anything to you.
So heres all the crazy numbers and stuff that i don't understand. Hope it helps, thanks
