[solved]Screwed graphics

Nope, same thing: Sometimes walls are missing - I don't know about missing objects.
I get a new message:
./penumbra.bin: ./lib/libCgGL.so: no version information available (required by ./penumbra.bin)
./penumbra.bin: ./lib/libCg.so: no version information available (required by ./penumbra.bin)
but I don't thing that's something important.

I've tried to turn of post effects - no change.
When I turn down the shader quality, I get additional errors that appear to be related to the depth buffer, but I saw these in other games, so I would assume it's a driver issue.
To sum it up, it seems to look like the ATI HD Problem that's posted in the Windows forum.
