Windows 10: nvlddmkm.sys, dxgkrnl, etc Latency Issues

Greetings, everyone. For the past few months, Ive suffered from stutters/micro stutters and for the life of me I cannot find a solution. My specs are the following: AMD Ryzen 5950X [Stock] Nvidia RTX 3080 FTW 3 Ultra [Stock] 4x 8GB 3200MHZ DDR4 TridentZ MSI X570 Tomahawk WiFi 1x Samsung 2.5 1TB SATA SSD 1x 2TB Seagate HDD 1x 6TB WD HDD EVGA 750W Gold 80+ PSU I would have just posted a speccy, but it seems to not like my CPU too much for whatever reason. Anyways, I have scoured these forums, guru3d, sysnav, and Reddit to try and get to the bottom, trying everything from setting PCIe to Gen3, updating and rolling back every driver that seems to even remotely cause an issue, and I even tried going through traces in WPA, which was wayyyy over my head. I am hoping someone has an idea of some kind, as Im getting desperate. Here below is my most recent LatencyMon, and below it I will try to include a trace. ____________________________________________________________________________________________________ _____ 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. LatencyMon has been analyzing your system for 1:12:21 (h:mm:ss) on all processors. ____________________________________________________________________________________________________ _____ SYSTEM INFORMATION ____________________________________________________________________________________________________ _____ Computer name: DESKTOP-3IMK363 OS version: Windows 10, 10.0, version 2009, build: 19043 (x64) Hardware: MS-7C84, Micro-Star International Co., Ltd. CPU: AuthenticAMD AMD Ryzen 9 5950X 16-Core Processor Logical processors: 32 Processor groups: 1 RAM: 32692 MB total ____________________________________________________________________________________________________ _____ CPU SPEED ____________________________________________________________________________________________________ _____ Reported CPU speed: 340 MHz 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. ____________________________________________________________________________________________________ _____ 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): 497.30 Average measured interrupt to process latency (s): 5.567518 Highest measured interrupt to DPC latency (s): 491.20 Average measured interrupt to DPC latency (s): 1.555345 ____________________________________________________________________________________________________ _____ REPORTED ISRs ____________________________________________________________________________________________________ _____ Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal. Highest ISR routine execution time (s): 171.810 Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0.000036 Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Total time spent in ISRs (%) 0.000042 ISR count (execution time <250 s): 119870 ISR count (execution time 250-500 s): 0 ISR count (execution time 500-1000 s): 0 ISR count (execution time 1000-2000 s): 0 ISR count (execution time 2000-4000 s): 0 ISR count (execution time >=4000 s): 0 ____________________________________________________________________________________________________ _____ REPORTED DPCs ____________________________________________________________________________________________________ _____ 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. Highest DPC routine execution time (s): 3400.510 Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 456.71 , NVIDIA Corporation Highest reported total DPC routine time (%): 0.001298 Driver with highest DPC total execution time: afd.sys - Ancillary Function Driver for WinSock, Microsoft Corporation Total time spent in DPCs (%) 0.004881 DPC count (execution time <250 s): 2403095 DPC count (execution time 250-500 s): 0 DPC count (execution time 500-10000 s): 34 DPC count (execution time 1000-2000 s): 0 DPC count (execution time 2000-4000 s): 3 DPC count (execution time >=4000 s): 0 ____________________________________________________________________________________________________ _____ 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. 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. Check the Processes tab to see which programs were hit. Process with highest pagefault count: svchost.exe Total number of hard pagefaults 581 Hard pagefault count of hardest hit process: 212 Number of processes hit: 27

DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

Hi,

For me those DPCs are originated by the Intel Intel(R) Serial IO GPIO Driver.





The DPC and ISR graph shows a lot of those DPCs spikes.

It seems that your driver is outdated (ver 30.100.1816.3 released on April 2018).





A newer version is available on the Dell Website for your computer model.





Update this driver and see if it helps.

 

DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

I tried the driver and it seems to have helped a little bit but I haven’t been able to test it out fully. However, due to other issues, like temperature when gaming, Dell will pick it up tomorrow to fix these issues. I doubt that it will help that much, but what can you do?

Once I receive the repaired laptop, I will check again! Hopefully they check this issue but I doubt they can fix it..

 

DPC Latency problem (Storport.sys, nvlddmkm.sys, dxgkrnl.sys, etc.)

Hi,

Usually, latencies are related to outdated or low performing driver.
Have you made an update to all your drivers? not only video and audio drivers.

you can use a tool like ''Driver Easy '' to identify drivers that need an update.

If you have tried all this stuff, you can record a trace with the Windows performance tool kit.
Here is a tutorial on how to download and use this tool:How To Record Windows Boot Trace Using Windows Performance Recorder (WPR) - ZineTek

What you need to do after installing the tool, is to run Windows performance recorder with the following parameters and reproduce the issue:
