    DPC Latency - ndis.sys

    Like many other users here on the forums, I am having issues with DPC latency, with latencymon pointing the blame at ndis.sys.

    What I've tried:
    • Installing updated drivers (Little to no effect)
    • Restarting, shutting down entirely, etc. (No effect)
    • Disabling the "get updates from many places" option (SEEMS to have had a small effect, but issue still crops up much more commonly than I'd like.)

    This hardware has run without an issue for ~5 years with a few upgrades (GPU, CPU, NIC) since. The issue only started the day before yesterday.

    • OS: Win 10 Home 64 bit (Ver 1607 build 14393.447)
    • CPU: AMD FX-4350
    • RAM: 8GB DDR3
    • MB: Gigabyte GA-970A-UD3
    • GPU: NVidia GeForce GTX 760
    • NIC: Realtek RTL8192CE Wireless LAN 802.11n PCI-E NIC

    I seem to have fixed this by completely uninstalling the device via Device Manager, then reinstalling it using the same utility I originally used to update the driver. Maybe it was a busted driver?

    I'll leave LatencyMon running, but I'm not having any of the issues I was previously having.

    EDIT: Within 5 minutes of me posting this the issues started back up again. They're less frequent now, but still very existent.

    I am having this problem with high latency as well and cracking sound/videos.
    I am unable to find a solution to the problem and I wonder if you had any luck in finally getting rid of the problem?
