Since starting SoD I've been plagued with seemingly random system crashes which drop me down to 640x480x4bit mode and completely black out the SoD window. Once it happens the first time for the night, it seems to happen more and more frequently afterwards. This may seem to point to a heating issue, but I have the issue in no other games, and never have prior to playing SoD. My first thought was that it may be drivers, but both 91.47 and 81.24 versions of nVidia drivers (I have a 6800) have the same issue. It's getting to be quite frustrating so if anyone has any other ideas I'm game to try them. Thanks in advance.
