Vista + ATI - Test problem. Please test!

MHaggag:
Have you tried the demo of penumbra overture? If so, what errors did you get?

I played the demo before, with a driver that is 3 or 4 versions older than the latest one. It works fine. And I have the full game, but with the most recent driver update, it no longer renders correctly--all levels of detail work, but lighting doesn't work: 'G' (lightstick or whatever it was called) has little effect, and 'F' (flashlight) doesn't do anything at all.

I pretty much gave up on completing it until ATi puts a driver that works, or I get another card
