Mouse sensitivity and polling rate

A few possible solutions:

-Update videocard software drivers

-Defragment or TRIM (SSD) your OS and game drive

-Make sure Windows is not updating in the background during a game (check windows update tab)

-Remove mouse software

-Update mouse software

-Test other USB port

-Re-Calibrate the mouse in the mouse software (calibration is sometimes removed on update or profile switch)

-Lower the ingame mouse speed and up the mouse basic overall movement speed

-Lower BFV graphics settings

-Disable background applications (including mouse software) during a game

-Preform a cleanboot of Windows

thank you for the reply, unfortunately after trying everything on that list I have the same results..

When using 1000 polling rate, my mouse sensitivity is off. when dropping it down to 125hz it is back to normal

I also found that the discrepancy of mouse sensitivity is worse when playing a multiplayer game (vs the test range). for some reason 1000hz polling rate and playing online make the mouse sluggish and about 3-4 inches slower.

I tried changing polling rates in other games and had no change in 360 degree distance with my calculated mouse settings.

Any other suggestions I can try? I have not tried a new mouse, however given that it works in every other game Im hesitant to believe my mouse is the problem.

did more testing..

If i use the command thread.processorcount 6, my CPU usage drops to 80% and my mouse works fine. Default, the thread count is 8 (i have an i7 6700k so that makes sense) but cpu usage bumps to 100%. limiting the thread count to 7 drops cpu usage to 90% but still get mouse issues.

No idea why this started being a problem, but at least that is a fix for it
