There aren't any corrupt graphics anymore... after deleting the profile and reinstalling DKS, and the patch anything is fine with that. Maybe it had something to do with the hotfix or maybe with the profile, I don't know. There were only two reports with that graphic glitch issue and mine (and hopefully also the one of the other user) is solved, so I really don't care that much what the problem was for now.

For the most people the resolution-problem is surely much more important. Not anyone reads in forums or is able to change such settings in a xml textfile.
