hello, when using latencymon i have this issue with wdf01000.sys it has high DPC count in short time (600K in less than 10 min while idle).
Is there a fix for that ? thanks

For me it goes up just buy moving the mouse. So I thought that's normal.

Mine is similar, 100k in 5 mins. Is this normal, expected behaviour?

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

I just found a solution that worked for me. Downloaded Iobit driver booster, found some intel drivers were corrupted, updated all the drivers from there. Now, no more 600k in less than 10 min, it only increases when i move my mouse.
