I updated to 12.10 drivers from 12.08 and so far just about all my games had a similar problem where the screen will just go blank and I can still hear the game and the game appears to be running ... wait 5 seconds or so and the screen return with my game still running.
I'm going back to 12.08 drivers since they don't exhibit this problem.
Anyone else having this problem?
