--- Comment #26 from Andrew Charles Hurst a.hurst@shef.ac.uk 2008-04-28 05:49:41 --- Could it be a memory management issue: the card I have has only 16MB RAM. I noticed some funny behaviour in thief 2 with it, where on switching back from the menu, the game would hang for 30 seconds, and then resume rendering with corrupted textures (all white with regular black blobs!).
There's a memory management config hack I can try.
