I tried absolutely all the parameters in the BIOS via scewin. USB ecc, xhci hand off, xhci legacy, disabled 8 USBs and left only 2 ports. Actually, all power saving for the processor is turned off, c-state off, p-state cheapset off, p-state gpu off. Yes, this slightly reduced the latency, but did not remove the bug with dpi switching.Slender wrote: ↑05 Jun 2024, 19:35Sems like hardware issue.

The only thing I understand is that this problem occurs on all versions of Windows and on Ubuntu (linux). I was unable to reproduce the problem on android 12 and snap 870.
you can check changes in regedit (after/before change) but im not sure you find some.
I have the same, when i hard-reset my mice (connect-disconnect sound), im feel better responce and speed.
Do you try disable / enable usb options (maybe some hidden) in bios?
Show me your usbtreeviewer.
It seems to me that there are some hidden states of the motherboard usb controller and every time you switch the dpi the controller goes to d0.
At least I tested several motherboards: msi x99 sli plus, msi b450 gaming max, asus b550 gaming and this problem was observed everywhere. Different processors, different motherboards - the problem is the same.
