    Stuttering with graphical and audio distortion.(During network usage)

    Hello all,

    I recently upgraded to new mobo and i7-7700k, and switched to windows 10. I have noticed that I get significant audio and graphical stuttering and distortion, which seems to happen worse during network usage. Below is a short 35 second analysis from LatencyMon, which highlights a severe stuttering/distortion event. Any help is solving this is greatly appreciated.


    ____________________________________________________________________________________________________ _____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 0:00:35 (h:mm:ss) on all processors._________________________________________________________________________________________ ________________SYSTEM INFORMATION_________________________________________________________________________________________ ________________Computer name: DESKTOP-KMTPJ5ROS version: Windows 10 , 10.0, build: 14393 (x64)Hardware: ASUSTeK COMPUTER INC., PRIME Z270M-PLUSCPU: GenuineIntel Intel(R) Core(TM) i7-7700K CPU @ 4.20GHzLogical processors: 8Processor groups: 1RAM: 32705 MB total_______________________________________________________________________________________________ __________CPU SPEED_______________________________________________________________________________________________ __________Reported CPU speed: 420 MHzMeasured 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.

The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops.

    Hi, you may like to search the forum for threads including 'stutter' - there are a number. You may find a clue there.

    My latency mon is perfect, even with Edge open and on line.
    As your problems, apparently, are only with on-line issues; does it do it with ANY on-line application or just with specific applications?
    Screenshots of the Latency Mon Processes and Drivers screens may help.

    I unfortunately changed multiple variables at once, and thus cannot be certain which was the resolution. But here are the two things I did:

    Updated Asus 270m-plus mobo bios.
    Updated audio and lan drivers (new releases came out last month)
    Updated Intel RST, and enabled it within BIOS.

    So far, things seem to be resolved. The stuttering, network lag, audio and graphical distortion, and multi-window video streaming is much improved.

    I hope this information can assist someone else to resolve their problems.
