Re: Turning off raw mouse input option breaks mouse movement
Windows 10 has issues with mouse movement when raw input is turned off in-games. Mainly on low sensitivity or DPI the mouse will hitch and not move properly, this may be the cause of your issue and seems to affect games across the board not just BF2. The issue does however seem to be improved on the insider preview builds not there may be other stability issues with those builds so caution is advised before using them. On the insider builds there also seems to be an issue where the mouse will randomly continue floating off in the direction you were moving it after you stop moving your mouse but this seems rare.
