    [W10ProV1703b15063 x64] DPC dxgkrnl & ndis

    I have been having a ton of issues with my DPC latency after installing steam VR. I re-installed all my drivers, then did a fresh install of Win10 and still cannot seem to shake the DPC latency issues. Can someone take a look at these logs and help me figure out what is happening. LatencyMon shows ndis.sys and dxgkrnl.sys are the two main issues. CPU.zip

    Hi rogueassasin132.

    If
    (big if) your motherboard is asrock Z170 Extreme7+, there's a beta bios 7.41 (or P7.41?) that fixes the Microcode for "Hyper-Threading", for your i5-6600K, and I'd try to update your bios to that one.

    Remember the precautions: system restore point, backup of your important files, system image, windows cd at hand...
