    High DPC latency in windows 10


    Recently, I have updated windows to version 2004 and i have found the DPC latency to rise. I used LatencyMon application to check the DPC latency and found the main problematic drivers are ndis.sys, acpi.sys, Hdaudbus.sys and dxgkrnl.sys.

    Here are the links to latencyMon and WPA results:

    I have tried following:

    a. Disabled C-state in bios

    b. Disabled unnecessary drivers

    c. Using high performance mode

    d. Disabled HPET

    e. Turned off Link power management in Intel Rapid Storage Technology.

    f. Turned off windows system sounds.

    g. Set Performance Options, adjust for best performance of Background Services

    h. Debloated the windows using debloat script from github

    PS. I can't go back to ver 1909 cause i have already deleted windows.old folder.

    Windows 10 High Dpc Latency

    I believe DPC Latency Checker does not support WIN 10. Please try LatencyMon and check.

    I had this issue so thought of sharing.

    Windows 10: High DPC latency (ndis.sys)

    Recently, my audio has been crackling and popping and glitching, and I wanted to see what the fuss was all about. I tried everything. Until I found out that my DPC latency was dangerously high. I ran it through the DPC Latency Checker and LatencyMon, and
    apparently the problem was "ndis.sys". I've literally tried EVERYTHING. Here's a list of what I've done to resolve this problem:

    • Updating drivers
    • Changing the power plan
    • Disabling the dynamic ticking
    • Updating the graphics cards drivers
    • Disabling Firewall
    • Disabling IPv6
    • Uninstalling Bonjour
    • Disabling Energy Efficient Ethernet
    • Disabling/re-enabling drivers
    • Adding PerfLevelSrc, PowerMizerEnable, PowermizerLevel, and PowermizerLevelAC values to Registry Editor
    • Uninstalling antivirus software
    • Modifying the "Start" value in the Registry Editor's value to 4
    UPDATE: Recently, the DPC latency has declined, which is good, however it still sometimes has latency-spikes and I still don't have proper DPC latency.
