Two guys on this page
http://www.subsim.com/radioroom/show...62462&page=153 also have the same problem.. also I somehow can't take a screenshot because soon after the campaign start the game crash.

It looks exactly like mine.
I already tried some of the suggested fixes like updating directX and fully reinstalling the game and it actually got fixed, but only for a short while. I play around with the historical missions and the tutorial for a couple of hours and by the time I'm going to start the campaign it became like that again.
