After messing around with a few testing apps, i noticed that my polling rate is fluctuating, specially when making small movements, and think that this is the cause of my mouse being inconsistent, just don't have any idea on how to fix this.

Yes, after a few days trying it feels the same as the other mouse, i've tried all of my usb ports and the result is always the same, and both mouse are wired, already reinstalled the drivers multiple times. could be a cpu or motherboard problem?

So that means that the problem is with my mouse? this below is the test with a very cheap mouse use.

Download mousetester and got this:

3 Years I got to upgrade my pc with motherboard, ram, cpu and added a NVME m2, ever since i lost complete control of my sensitivity in game (went from a 4.5 kd in apex to struggling to mantain 1.0, using the same mouse, sens, dpi) I thought it could only be something in my head, that I was the problem, so i gave up and went to play other types of games, and then last week decided to play apex again, and the same problem(i've tried every sensitivity range of motion, to 1/cm360 to 50/cm360 and i couldn't play better on any of these) continued, so i decided to try and find a fix, and then i came up to the idea of updating my bios to see if it fixed, and it worked, my aim was perfect again, i could feel the difference and i became consistent again, but this only lasted for 3 days, then the problem came back. Does anyone have gone through something related? could my motherboard defective? i really want this to get fixed.
