Mouse issues

[Jean Paul Richter]

Hey,
I got a huge issues atm with my mouse jumping around just when I play freelancer, otherwise on desktop or other games it moves smoothly.
So its not PC issue since I run on octa core CPU, 16gigs ram and 6gb GPU
Its not caused by mouse sensitivity since I had the same in every single game plus I got both weighted mouse and precise dpi control
Its not frame rate issue since I run DX tory with frame limit at 60fps.

Can anyone give me anymore suggestions or something like that, since when I do PVP in general and I have to move mouse like 1mm it jumps around more than that?
Any smoothing software usable with Ds FL or anything else?

Thank you in advance.
