the mouse seems to be very sluggish.
if im under fire and in a firefight i feel very VERY disabled.
i feel like im not in control over my char.
i feel like my skills will not be in effect as im playing.
the mouse accelerates sometimes and sometimes its fine.
ive heard of countless other people who have this issue to.
i would think this a high priority to fix.

example: i hear someone walking up behind me i turn around as fast as i can to see whats going on.
oh no my mouse is all weird, the faster i try to move the slower my mouse is.
sort of like an opposite effect of acceleration.
