Strange sensitivity problem, Help

Hello all!

I’ve got a strange sensitivity problem that only occurs on Faceit servers.
So basically it literally halves my sensitivity randomly, and then it goes back to normal.
It happens very frequently, it makes the game totaly unplayable, i can’t develop muscle memory this way.
On all other 128tick servers, 64 tick servers, MM, working fine.
It might be because of anticheat, but im really not sure.
Anticheat keeps blocking these files, do they have something to do with this?
Blocked file C:\Program Files (x86)\NVIDIA Corporation\3D Vision\nvStereoApiI.dll
Blocked file C:\Program Files (x86)\NVIDIA Corporation\3D Vision\nvSCPAPI.dll

My launch options, if they can help, I’m really out of ideas:
-dxlevel 80 -novid -freq 60 -refresh 60 -console +cl_interp 0 +cl_interp_ratio 1 -high -nojoy -nod3d9ex1 -noaafonts +mat_queue_mode -1 +mat_vignette_enable 0 +mat_postprocess_enable 0 -threads 2 +exec autoexec.cfg -no-browser -d3d9ex

EDIT: I’ve tried reinstalling.
