The crashes seem to be more frequent on some missions then others. I made it to Kaldir and on the first mission it has crashed numerous times. Some of the missions prior to this the game seemed to run fine.
What seems to happen is the video driver will crash, both of my monitors will go a solid color (the color is completely random sometimes it will be red on both, sometimes blue, sometimes a different color on each) and the sound will get messed up just like on a normal crash.
Now sometimes the computer will comeback to the game and you can play it for another minute or so before it crashes again, sometimes the computer will restart, and sometimes it will just sit on that solid colored screen.
Ive tried several different drivers, Ive tried disabling my sound card and other devices, even reformatted my computer last night (yay...) but none of these work.
Ive been able to adjust the settings within the game to prolong the crashing, but the crashing happens none the less.
Never had an issue with any of the other games i play. My current setup is only about 8 months old.
