    High DPC latency dxgkrnl.sys and nvlddmkm.sys


    Hi,I have recently bvuilt a new PC, but it's unplayable due to high DPC latency. I've had this for over a month now and I've done everything:Updated latest BiosIn Bios I've disabled onboard graphics, sound, wifi, serial connector, network, stack and power saving PSSDriversI've updated AM5 chipset drivers for motherboard from AMD. Updated LAN drivers from Realtek, updated latest Nvidia drivers using NVClean.I'll done 3 clean reinstalls of windows 11 and I've tried many other "fixes" from every corner of the internet, max power, turn of virtualisation, used MSI app, etc, all to no avail.

    DPC Latency High Crackles popping dxgkrnl.sys, nvlddmkm.sys, USBXHC

    So I bought a new computer.
    And the problem of crackling and bouncing back.
    It is important to note that my previous computer also had the same 3080 video card.
    Beyond that all the hardware is new.
    I need help attaching information about the problem I have I would love help from anyone who understands.

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    It seems that your driver is outdated (ver 30.100.1816.3 released on April 2018).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