Latency problems since last couple Win10 updates

In the last week it seems several updates have been pushed to my Win10 laptop and now I have significant latency issues affecting overall sluggishness and streaming audio (not locally stored media). The latency monitor identifies ndis.sys as the latency hog. dxgkrnl.sys seems to be the IRS hog. How can I resolve this, either by rolling back ndis.sys or to a previous OS version or other?

The last updates were KB4480979, KB4480056, KB4462930, though the problem seems to have started with a large update a day before that, which Update History does not want to show me.

Latency report follows:

CONCLUSION

_________________________________________________________________________________________________________

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES

_________________________________________________________________________________________________________

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   22185.20

Average measured interrupt to process latency (µs):   17.867951

Highest measured interrupt to DPC latency (µs):       22168.70

Average measured interrupt to DPC latency (µs):       4.546608

    Hi Bruce,

    We haven’t heard from you since your last reply. Kindly update us with the status of the issue. We have been researching on this issue and would like you to try a couple of steps and see if it works.

    Change Power plan

    Change the power plan to High performance or Power saver and see if it makes any difference.

    Disable dynamic timer tick feature

    Open Command prompt in admin mode.

    Type bcdedit /set disabledynamictick yes and hit the Enter key.

    Reboot the computer and check the status.

    Enable the dynamic timer tick in case, disabling it doesn’t help.

    I would also encourage you to post your feedback and suggestions on Windows 10 Feedback Hub app to help us improve your Windows experience.

    Send feedback to Microsoft with the Feedback Hub app

    I have also sent you a private message, please click on your profile name, select My Profile and choose View personal messages.

    Hello BruceW268,

    Thank you for writing to Microsoft Community Forum.

    I appreciate you for providing us the required amount of information. I understand how difficult it feels when the PC becomes sluggish. For us to isolate the issue, kindly check with the below methods and see if it helps.

    Method 1: Processor power management.

    • Click Start and select Settings > System > Power & sleep.
    • Click on Power Options.
    • Click Change Plan Settings next to the selected Plan.
    • Click Change Advanced Power Settings.
    • In the Advanced settings, scroll down to Processor power management. Make sure the settings as highlighted in the red boxes are all set to 100%.
    • Click OK.

    **Method 2:**Update network adapters.

    Addition to the previous suggestion, kindly download the latest network adapter drivers from the manufacturer’s website. If the latest version doesn’t help, install the driver prior to the version if available.   

    Method 3: Microsoft Safety Scanner is a scan tool designed to find and remove malware from Windows computers. So I suggest you to run the scanner to improve the PC performance.

    Hope it helps.

    Hi,

    As it took a while to research on this issue and checked with the research team. We would like you to troubleshoot on the issue with the steps given below.

    However, the latency issue is related to ndis.sys but we want to know the root cause of this issue and since we are providing a workaround.

    Step 1:

    Disable/Turn off Microsoft ACPI-Compliant Method Battery in device manager. But before doing this, uninstall Intel Dynamic Platform and thermal Framework.

    1. Press Windows key + R. This will open Run. Alternatively, you can go to Start and search for Run.
    2. In Run dialog box, type devmgmt.msc and hit enter.
    3. Now expand the Intel Dynamic Platform and thermal Framework.
    4. Now right click on the Intel(R) Dynamic Platform and thermal Framework Managerand click on Uninstall.
    5. Now click on the check box remove the device driver from the computer.
    6. Click on OK.
    7. Now expand Battery.
    8. Right click on Microsoft ACPI-Compliant Method Battery and click on Disable.

    Step 2:

    I would suggest you to install the chipset from manufacturer's website and install them in compatibility mode. Refer the article Make older programs compatible with this version of Windows. The reason we are installing the drivers in compatibility mode is because the drivers are only available for Windows 8 and older versions.

    Please get back to us with the updated information on the issue to assist you further.

    I did all of the above with no change. I did get my ISP to restore a previous version of the router firmware, which halved my latency and stopped the streamed media glitching, though the latency is still very high.

    Before that:

    I prevented CPU throttling through Advanced Power Mgmt, to no effect.

    The network and graphics drivers were mostly current and so could not be updated. I uninstalled them and let the system reinstall the current version. In one case my Nvidia driver was a little out of date which I updated. No effect.

    I ran a Full scan of the MS Safety Scanner (many hours) which found nothing.

    So the streamed media glitching was resolved by restoring router firmware to a previous version. But I still have rather high latency and a sluggish system overall more recently, so it would be good to know if it could be related to a Windows 10 update in the last week (or month)?

    I can supply the new latency report if that is helpful (though a bit long).
