I found a true solution and I wrote it here:
Fixing is super simple by 3 steps:
- Open Powershell with Administrator privileges
- powercfg -SETDCVALUEINDEX SCHEME_BALANCED SUB_PROCESSOR PROCFREQMAX 4000
3. powercfg -SETACVALUEINDEX SCHEME_BALANCED SUB_PROCESSOR PROCFREQMAX 4000
now enjoy your lag free mouse experience. the number 4000 is a very cautious choice, you may turn it up to a value like 4100 or even 4200 if you like. But 4000 won't be causing any problem, and 4200 might be unstable. So change it on your own behalf! The larger the number is, the better the frequency can be (no more than 4.2GHz, that's the hard limit of the CPU). But as you put in a larger number you might encounter the problem of stuttering again. So find your own number. Mine worked fine at 4000 and 4100. Actually you won't loss anything for setting 4000 in a realistic way though..
Thanks for sharing.
This works for the mouse legs well, the audio problem sadly still is present.
