Game Freezes (Rendering + Input) with Catalyst 11.5?!

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install newest ATI Catalyst 11.5 Graphics Drivers
2. Play any Nullpo Mode, e.g. Line Race

The game freezes (complete rendering + inputs) from time to time for about 1 to 
5 seconds. It seems to happen faster and more often in multiplayer, but 
normally always happens after at most 1 minute after game start, also in 
singleplayer.

This can't be categorized as some kind of lag anymore and makes the whole game 
literally unplayable.

I did not have time yet to verify, if it is really only related to the Catalyst 
11.5 Drivers. I noticed the problem first after installing them though. 
Feedback from other users would help alot here.

I'm testing on a Radeon HD4870, running Win7 x64.

I quickly tried a couple different rendering settings (vsync on / off, perfect 
mode etc., no scaling), but even a "out of the box/zip" Nullpo 7.5 behaves 
exactly the same.

+ current r806 build shows the same symptoms
Also note that the handling of the pieces (input delay) and general 
reactiveness is much worse right at the start of every game, feeling like 
strong lag (also in sp).
