Hello!
I had similar issue with freeze animations (redrawn problem) on ATI graphic card. To solve the problem with freezing screen, you just need to 'switch on' vertical sync (refresh) in your catalyst control center and enjoy the game play.

Interesting. I'm using
RivaTuner and it comes with a tool called "D3DOverrider". It detects 3d acceleration and applies Vertical Synchronisation. You can adjust other things aswell.
This trick will only work if "Hardware Acceleration" is on, in my opinion.
