Good day,

I have ran latencymon several times up to twenty minutes and every time it comes with red warning - excessive latency. At first it detected HdAudiobus.sys, I managed to reduce this a lot by disabling monitor's speakers via output devices - AMD high definitition audio device. At the moment there are two other offenders ntoskrnl.exe and Wdf01000.sys

I could use some help to find out what is causing this

I tried following the guide how to troubleshoot the traces myself, but I can not narrow it down to a single driver. Here are several more traces, hoping that it would catch the issue. Desktop is idling during trace capture

During clean windows 10 1903 installation, I only installed these drivers manually, none other were updated. I do not know where to find usb and others if necessary.
