    Windows 10 - x64 High Latency with stuttering and audio dropouts

    I appreciate in advance that this is a complicated issue to seek help on. I've spent days going through as many tweaks, tips and approaches to testing and trying to rectify this issue but to no avail.

    I suspect I had on-going latency issues for a while that were a mild inconvenience but since the Creators update the stuttering and latency is making the entire system borderline unusable, or at least extremely unpleasant.

    The stutters are causing audio dropouts, fps drops and freezing in games and ping spikes as the Ndis and Network Card are spiking.

    I read a couple of threads where people here were kindly helping others to work through these issues so I have attempted to gather in the appropriate logs to assist any troubleshooting, should anyone be willing to help.

    I'm currently a mature student so fairly tight funds wise but have 20 in amazon vouchers I'll gladly give to any technician who assists me in working through this. I'll also make a donation to the site.

    I've done a fresh install of Windows 10 (x64 retail) and installed the drivers from the Asus website.
    I've also reset the bios to default.
    Finally I tried downgrading the Realtek onboard LAN driver to Windows 7 as this has been suggested a lot as a culprit/solution.

    Other investigating with Latency Monitor suggests the problem is reduced when the LAN nic is disabled. But I left the monitoring running overnight without the LAN and the system still had latency issues.
    I did try disabling the NIC and using a tplink wifi dongle and that caused the most severe latency issues of any hardware.

    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.
    LatencyMon has been analyzing your system for 1:43:51 (h:mm:ss) on all processors.

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 3398 MHz
    Measured CPU speed: 1 MHz (approx.)

    Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

    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 (s): 2654.304023
    Average measured interrupt to process latency (s): 3.736664

    Highest measured interrupt to DPC latency (s): 2651.591859
    Average measured interrupt to DPC latency (s): 1.180054

    _________________________________________________________________________________________________________
    DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

    REPORTED HARD PAGEFAULTS
    _________________________________________________________________________________________________________
    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.


    Process with highest pagefault count: none

    I've attached DxDiag & msinfo32.

    If anyone has the time and kindness to help me with this I would appreciate it enormously, this is an incredibly frustrating issue to run into. I'll gladly pass on that voucher as a small token of my gratitude to anyone who assists and I'll undertake any testing or logging exactly as requested. I wouldn't intend to waste anyone's time here.

    Thanks.

    Re: Windows 10 - x64 High Latency with stuttering and audio dropouts

    Hi. . .

    Make sure that your BIOS is the most recent version available.

    Make sure that your video, audio, wifi, and Ethernet drivers are updated.

    Obtain the driver name from Device Manager (devmgmt.msc), then look it up in the DRT for the update site -

    Driver Reference Table

    If you have an Internet Security Suite (ISS - 3rd party firewall + AV) installed, uninstall it with the removal tool, if available. Run removal tools for any other ISS' that were installed in the past.
