Inconsistent mouse DPI - FIXED

Hello, i have very strange problem, my mouse sensitivity is extremely inconsistent and that inconsistency correlates with games FPS. For example i have in game around 120 fps and if it goes higher or lower, my mouse sensitivity goes to hell, can’t barely move it. When i turn on vsinc ant that capes it at 60 fps, it plays wonderfully until in a major with it drops like 5 fps and in that moment i lose my sensitivity. Tried almost everything, reinstalled all drivers, downgraded drivers, different DPI settings, different mouse, followed every tip in turning off any mouse acceleration. I currently play at 1400 dpi with 5 sense in game. My laptop dell Inspiron 7577 gaming - 1060 Max-q, Driver 397.31 I5 - 7300HQ, 8 gb ddr4 one stick, resolution 1080p, NVEM ssd 256gb.

Update

Fixed my issue by opening it i admin mode…

This doesn’t sound like a problem with the mouse but overall system performance. Usually when I have a symptom like this I do a full uninstall and reinstall of the graphics driver (make sure to use the Display Driver Uninstaller from Guru3D to ensure it completely cleans out old files) and then download the latest driver from NVidia.
