Do you have s3tc support enabled?
Yes.
For me only in lower as possible graphics options game is playable and most textures looks normal(game is quite dark so hard to say).In higher graphics detail indeed textures are black :/
The game is quite dark and the gamma setting seems to have no effect. From my tests, a good LCD makes a big difference.
