[solved]Screwed graphics

[Gert]

Well, I don't have anything like compiz running.
In addition: I can run Alienarena, UT2004, Doom3 (and games based on it's engine) without problems.

Out of curiosity since CG is essentially a NVidia creation, is it really supposed to create proper code for an ATI card?

I forgot to mention about the Intel Graphics: Here the walls were there, but the lightning looked somewhat strange. And, of course. as soon as I went to a bigger level, the frame rate dropped to nearly unplayable, but I would guess that's to be expected.

BTW: If you feel it could help, I'd happily run a special executable compiled to do more logging or something like this.
