I have tried EVERYTHING I found within a time span of about 2-3 hours on the internet reguarding this issue. My issue is my sensitivity going super fast and super slow randomly. I have a Logitech G9x mouse.

I have tried enable/disable vsync (frame rate cap)

Un-installing video and mouse drivers

Fooling with different dpi settings on the mouse software

I ran the mouse acceleration fix for windows. 1:1

The game is un playable, I have not been able to play for about 2 weeks now. Why have a $60 dollar investment on something I can not use? If I can't get this fixed im going to demand a refund.
