Severe mouse jitter/jumping...

[Silithas]

Both in SP and mp i get severe mouse jump and it makes a bigger jump the faster i aim around...

How the heck can this be fixed?

Ghosts got it fixed by setting the cpu priority from high to normal, but this game is already at normal...

Did you try bumping it down to "Low" to see if that fixed it?

Nope, still jumping.

I had to "turn off" my Logitech G500 mouse acceleration setting. It stopped my mouse jumping.
Might want to try that, if you haven't already.
Good Luck
