Plutonium

So I am having this problem where when I turn the mouse acceleration jumps from none to alot based on how fast I turn.

I have tried

1. disabling the built in windows mouse acceleration.
2. changing my Display mode.
3. changing my mouse polling rate.
4. changing my fps cap.
5. entering "cl_mouseaccel 0" in console.

None of these seemed to have fixed it.

Any help would be amazing.
