    This driver in specific or other versions are affected as well? The first course of action would be to use DDU+ Install latest WHQL driver.

    LatencyMon has menu item for copying text report to clipboard, so you can paste it here.

    Not related directly to DPC but you can check in Device manager whether videocard has IRQ shared with some other device.

    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 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 0:01:00 (h:mm:ss) on all processors.

    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): 9644.815746
    Average measured interrupt to process latency (µs): 3.338121

    Nothing suspicious in text report. Have you checked shared IRQs in Device manager?

    Are you running any software that monitors power, fans etc? I've had issues with Aida 64 causing constant latency spikes in Win10. If you're running Afterburner or Precision those can be suspect as well.

    How do I look for shared irq's and also I have realtemp gt for monitoring but its disabled most of the time.

    I'm guessing video card is sharing irq with chipset?

    With USB controller. Not good. You can use this tool - http://www.mediafire.com/file/2kkkvko7e75opce/MSI_util_v2.zip - to switch videocard to MSI mode. But only videocard.
    More on MSI topic - https://forums.guru3d.com/threads/windows-line-based-vs-message-signaled-based-interrupts.378044/

    PS Also if you put any USB devices to Renesas ports you can try drivers from Renesas
    https://www.win-raid.com/t834f25-USB-Drivers-original-and-modded.html

    PS Run tool as Administrator, set the check for videocard, click Apply button, and then reboot and try LatencyMon again..

    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. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

    What software are you running default on your system? I would open task manager and start killing processes until you find the program that is causing issues.

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 3411 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 (µs): 31001.271019
    Average measured interrupt to process latency (µs): 3.768378

    Highest measured interrupt to DPC latency (µs): 410.664550
    Average measured interrupt to DPC latency (µs): 0.965308

    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
