    Question Windows 10 audio stuttering and dxgkrnl.sys latency

    Hello everyone. Hope somebody can help me with my problem.

    My computer freezes and audio stutters absolutely randomly regardless to the system load. It can happen during running a heavy game like GTA5 or when it is simple online radio is playing.

    I've read tutorials posted here about DPC Latency and here what I've got:

    1) After two audio stuttering episodes LatencyMon software showed me that dxgkrnl.sys is on top position in list of Total Execution times (ms), x3 bigger than second driver in list.

    2) xperf generated trace file opened by WPA shows me a huge spike on "DPC Duration by Module, Function" graph, right in time when audio stuttering appeared, and that spike belongs to dxgkrnl.sys driver.

    Driver Reference Table says that dxgkrnl.sys driver belongs to Windows DirectX core system, I did not found any way of updating it in Windows 10 using Google. What can I do with it?


    My PC specs are: Core i7 4770K, ASUS Z87-PRO(v-edition) motherboard, one GeForce 980Ti from GigaByte, 32Gb ram by Kingston 2400Mhz, SSD-disk by Kingston 120Gb, Sound Blaster Z audio card, 1200W PSU by Corsair
    All drivers are updated to the latest version from manufacturers sites.
    There is 100% no shitware or viruses on PC. Overclocking is off, BIOS settings are factory default or auto.
    Windows 10 system is clean installed from flash drive after formatting.

    Problem solved by rolling back to older VGA driver.
