Mouse movement in full screen mode: buggy


Just bought the game on steam, and am trying to start a game. First thing I noticed is once in full screen mode, the mouse movement is buggy. At low movement speeds the cursor will get stuck and simply not move. There is also some lag which is a bit frustrating. It seems like there is some mouse acceleration issues in full screen mode?

In windowed mode I have no issues (or of course in general Windows 7 env).

Using a quad core with an ATI 5870 - so it isn’t a performance thing… Can anyone help? makes it very hard to play…
