Video Driver Issue causing hangs and bluescreen
I'm not kidding
About once an hour or so playing the screen will hang. The music and sound effects continue playing, and after about 20 seconds the screen goes black and then comes back and everything works again. Windows informs me that my video driver crashed and had to be restarted. Sometimes this crashes the game completely, sometimes it causes a bluescreen.
There's no obvious event in-game that precedes this behavior, so it's unpredictable and I can't reproduce it at will. Because it happens so uncommonly it's very hard to find the problem, because after changing a setting I have to play for an hour or two to see it happen again.
Any ideas?
Oh and here's my DXDiag.
