I have gotten many BSODs lately while testing a mod map, different map each time, the only consistent traits are the use of lighting and other settings from shipped maps (to have a sun, water, and grass) but according to google some other people have the same problem, it seems to always be related to affinity, the downside of playing the Steam version in this case is how Steam locks the affinity options from the task manager on games, time to get a crack I guess.
If you have experienced BSODs while playing please leave a comment just to confirm.
