    DPC Issues WDF01000.sys

    Probably beating a dead horse but. I've done tons of "fixes" for the DPC issues, and I'm still getting them.
    Any suggestions?
    I have HPET off in bios and in windows. I've done dynamictick disable. I've done TCP optimzer. I've done core unparking. I've done NVIDIA removal and clean installs. I'm a streamer and gamer and it is so aggravating to deal with FPS hiccups.

    Thank you for your time and answers.

    I have a EVGA 1070 SC.

    Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

    Please use the Windows Performance Analyzer to provide us with your trace file. The trace file will probably be too large to upload here, so host it from a third party site like Dropbox or Microsoft OneDrive.

    Windows 10 SDK - Windows app development

    How to Diagnose and Fix High DPC Latency Issues with WPA (Windows Vista/7/8) (similar steps can be used with the Windows 10 WPA)


    Please also provide your dxdiag and msinfo32 reports:

    Open and run DxDiag.exe

    This tool is used to collect info about devices to help troubleshoot problems with DirectX sound and video. A support person might ask for this info, or you might post it in a forum when you ask for help.


    • In Windows, select Start and enter dxdiag into the search box on the taskbar. Select dxdiag from the results.
    • In the tool, select Save All Information for an easily shared format.



    Run msinfo32

    Open an instance of elevated command prompt:
    • Log on to your Windows 10 computer using any account of your preference.
    • Once on the desktop screen, right-click the Start button.
    • From the context menu, click Command Prompt (Admin) or Windows PowerShell (Admin)
    • If you opened Windows PowerShell, type
      Code:
      cmd
      to start the Command Prompt


    • Type the following into the Command Prompt
      Code:
      msinfo32 /nfo %USERPROFILE%\Desktop\msinfo32.nfo
    • Zip the msinfo.nfo file up (found on the Desktop of your administrator account) and attach it to your next post
    I am only a volunteer helping users on the forums. Please wait 72 hours before double posting or PMing for help. I appreciate your patience. :-}

    Re: DPC Issues WDF01000.sys

    Did you have a hiccup while doing that scan? I see a slightly high latency due to your NVIDIA drivers, but not much else.

    Have you tried different BIOS settings to see if any changes provide less latency?

    Have you tried disabling your NVIDIA High Definition Audio device when not in use (Device Manager -> Sound, video and game controllers)


    Make sure your display card is seated properly in your motherboard.

    bios settings like what?

    Something similar to the above. The user turned the Enhanced Memory Performance off and experienced less latency with it off.
