    I run my laptop for real-time audio processing, but after many optimizations I still get glitches, culprit drivers are :1- wdf01000.sys2- ntoskrnl.exe3- rspll64.sysAll 3 above drivers have very high dpc latency which is affecting the operation of my audio software.What can I do to further optimize, and reduce my high dpc latency issues?All drivers, bio, chip set are up to date, so is win 10.Pls advise, tks.

    High DPC Latency caused by wdf01000.sys

    Hello,

    I am posting this regarding a problem that I ran across in my laptop at the beginning of august 2019, the problem is that I am getting high DPC Latency levels that are apparently caused by wdf01000.sys according to the latency checking
    program, latencymon.

    I really want to know if there is a fix since I have browsed a wide range of sites trying to find a fix, I could not find any. And also my keyboard stopped working for some reason, if its ok I would like to find a fix for that, but
    I prioritize fixing the high latency over the keyboard.

    Thank you for taking your time to read this.

    Wdf01000.sys Latency - Windows 10

    Hi,

    Wdf01000.sys is a Microsoft driver file. The wdf01000.sys
    process should not be deleted or prevented from loading each time Windows loads.

    We would like to know more about your wdf01000.sys and latency concern:

    • Were you getting errors with wdf01000.sys? If yes, Can you send us a screenshot?
    • Which program or application were you using in audio recording?
    • What equipment or devices were connected to your PC when you were recording audio?

    In the meantime, check out this article for tips on how to improve
    PC performance.

    Looking forward to your response.

    Unfortunately updating logitech software did not help.

    So is there any way to find out which program or hardware uses that Wdf01000?
