  1. DPC Latency issues caused by dxgkrnl.sys on 20H2


    Hi all, I've recently been having DPC latency issues that I believe are being caused by dxgkrnl.sys. At this rate I have absolutely zero clue what could be causing it, I've followed through with multiple forums, and every single person I've seen that's had this issue has had a different solution and none of them have worked for me. This originally started out on 1909 out of nowhere, I can't think of any software I would have installed that might have caused it. I went through many tests, uninstalling different programs, updating windows, going into device manager and disabling v

    DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

    Hi,

    For me those DPCs are originated by the Intel Intel(R) Serial IO GPIO Driver.

    The DPC and ISR graph shows a lot of those DPCs spikes.

    It seems that your driver is outdated (ver 30.100.1816.3 released on April 2018).

    A newer version is available on the Dell Website for your computer model.

    Update this driver and see if it helps.

    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.

    DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

    I tried the driver and it seems to have helped a little bit but I haven’t been able to test it out fully. However, due to other issues, like temperature when gaming, Dell will pick it up tomorrow to fix these issues. I doubt that it will help that much, but what can you do?

    Once I receive the repaired laptop, I will check again! Hopefully they check this issue but I doubt they can fix it..
