Interesting.

Did you disable it in the playback devices list after keeping it enabled in device manager?

wdf01000.sys DPC count relates to USB (3.0) usage

Higher numbers should mean higher polling from your USB devices, not necessarily some driver problem

This distinction applies only to Ryzen, that's why your mobo manual doesn't list it. Thanks for the reply, does that mean Intel doesn't even have a CPU-connected USB-port at all because in one video someone said it you should put your usb devices into the Intel-USB-Host controller. Yes The video yo...

Hey, r0ach, glad to see you here. Your threads on OCN basically founded the tweak community. About your finding, for anyone interested in this issue regarding fans/molex, there is an almost 10 year old thread on OCN discussing it: https://www.overclock.net/threads/after-years-of-troubleshooting-i-ha...

Isn't this because every time the mouse updates it must interrupt the gpu (nvidia) to draw it on the screen, also consider trying software cursor vs hardware cursor. Use this tool for realtime (windows APIs) OR optionally use registry below. https://www.monitortests.com/forum/Thread-SoftCursor Enab...

FYI, all USB ports on Intel go through the Chipset. If you have an 11th gen intel CPU or newer, the primary M.2 slot is connected directly to the CPU. You can use a USB to M.2 adapter in that slot to bypass the chipset. I'm using this one. https://www.ebay.com/itm/284929644313 https://www.newegg.ca...
