It crashes while an SpaceObj is being created. Would need to test that somewhen later with proper background data 
Maybe something that shouldnt be there. I remember to have had this crash when i freshly started MP and just head to X. The game crashes as soon as i entered X (the white flash in the video sequence while jumping).
That is exactly the point when the game crashes! When I jump from Custodian to X, there's this first worm hole tunnel-effect, and when it is supposed to show the white flash and the second tunnel-effect with slightly different colors/graphics/textures, game just CTD. I never get the crash when I jump between New York and Custodian, and I haven't progressed in the SP further to try jumping anywhere else.
Needless to say, my computer is running just fine with a lot of different games, lemme see what I have installed ATM: Driver SF, Trine 2, Witcher 2, NFS The Run, Civilization V, Dirt 3. CF is the only game where the crash happens in exactly the same point every time, so that would prove that there is some kind of compatibility issue.
Swat: I can run Prime 95 for hours without a hitch, so I would say my set up is stable enough.
But I appreciate for all your help, hope you can figure it out.
