    DPC Latency under load making everything unplayable

    Hi, I've tried everything. Basically, under load, after a bit of time DPC and ISR latency makes everything a slideshow with crackling sound. I have no idea what's causing it. Latencymon is showing dxgkrnl, hdaudbus, storport ntoskrnl and wdf01000 as potential culprits. These are all windows drivers and I have no idea what to do!

    I've run driver verifier, no BSOD. I've disabled all sound and internet cards in device manager, no improvement. I have literally no idea what else to try! I've also updated every driver and even the BIOS. I've tried disabling onboard audio and video in the BIOS also.

    Any ideas?

    Hi, good that you know about that tool (presumably LatencyMon). There are several threads here where people have dealt with or are attempting to deal with this. Good that you've updated the BIOS.

    Driver management - Uncle MS maintains key drivers on Win 10 - so that's most PC drivers. If the version installed is older or newer they will be replaced unless you take special action.

    Now we don't know your history or any details about your PC.

    So, has your PC previously successfully been running Win 10, or did these problems start after installing/upgrading to Win 10?
    Is yours a clean install or upgrade?
    Is your PC listed by your manufacturer as Win 10 compatible?

    Could you please complete your specs?

    Do you notice either of these?
    - System Interrupts uses a lot of CPU time
    - System and compressed memory uses a lot of CPU time

    You can do an advanced search of the forum - text of posts- Latency to find more. Tends to be hard to resolve.
