ESC> options> look> adjust the sensitivity and enable smooth mouse if you have too...

That doesn't help, and smooth mouse is already on

Fixed it!

 

I replaced the config_m2 (from alteriw folder) with the config_m2 in the steam folder, and now it works proper :mrgreen:

 

But still no idea what caused the problem...

Disable the steam overlay ? Can be a solution(worked for me in battlefield 3 - origin overlay)
