I had it freeze in a common house last night. I`m not sure if sound was playing as I turned the music off (like I'd hear it over the 280 noise). The pc hadn't crashed tho, just the game.
That game crashes loads on me. Crashes to the point that I have to Ctrl+Alt+Del and end the process. Gives me an error message, and then I can start it back up as usual. Its just a buggy game IMO, lots of little fiddles wrong with it. Awesome gameplay though. One of the best games I've played in a while.
