Windows 10: DPC latency due to dxgkrnl.sys

MSI X-570 A PRO

AMD Ryzen 7 3700x

AMD RX 6800

Corsair Vengeance DDR4 3200 8GB x 2



I've been having an issue with dxgkrnl.sys causing some fps spikes and audio drop out/pops, i have tried reinstalling windows, reinstalling drivers for motherboard and my GPU, Changing ram timings in bios and using a different monitor, all to no avail


i'm sure it's something to do with fullscreen because it doesn't happen if i game in windowed mode.


Hoping to get some feedback on what i can do to try fix it.

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 0:00:23 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: 27696.90
Average measured interrupt to process latency µs: 12.424255

Highest measured interrupt to DPC latency µs: 27693.90
Average measured interrupt to DPC latency µs: 9.580774

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.

_________________________________________________________________________________________________________
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: onedrive.exe

Total number of hard pagefaults 93
Hard pagefault count of hardest hit process: 71
Number of processes hit: 7

DPC latency from dxgkrnl.sys win1909

Hi all, i'm trying to fix this problem from ages.

I have updated all drivers/bios, tried all possible fixes on internet (Hpet, MSI mode, tricks on audio devices ecc ecc).

I'm on a fresh win1909 installation from media creation tool. Bios default settings (xmp enabled and tried without).

I can reproduce pops the moment when i run a program (whatsapp, steam and others), but they can appear randomly when i listen music or other simple things.
Many games are fluent but some stutter every 1-2 min for less than a second. It's a "total" stutter, not only audio.

From my experience i can say that there are some "good" boot-ups with no issues at start, but they can appear after some hours. No fast start or hybernation by the way.

LatencyMon is not very helpful, some random wdf, ntoskrnl e dxgkrnl latency. If I disable the video card driver, latency reduce by a lot (tried both gtx1060 and 5600XT same result).
So the main culprit appears to be dxgkrnl but i can't isolate the problem, tried to disable every single driver from devices manager.
Stressed out ram and cpu with all classic tests, no problems speccy full analysis.txt

Last thing, i've done a trace during a couple of pops when i run whatsapp (two times) GD link --> DESKTOP-PTCT7LR.03-22-2020.22-05-51.etl - Google Drive

Thank you in advance, sorry for my english

 

DPC Latency with Storport.sys and Wdf0 1000.sys

Sorry when I went to post it looked much better than it does there.... So I can see how that wasn't the greatest piece to look at.

Here is the screenshot you requested.








Power Plan Settings: High Performance
Turn off disk after: 20min
Sleep/Hibernate: Never
USB Selective Suspend Setting: Enabled
PCI Express Link State Power Management: Off

Processor Power Management

• Maximum Processor Frequency: 0MHz
• Minimum Processor State: 100%
• System Cooling Policy: Active
• Maximum Processor State: 100%

I believe the Power settings are mostly the generic High Performance. If I changed anything it was the sleep function as I often access this computer when I'm at home.

As for staying with my old computer. I agree, I definitely could have, but it had been 3 years since I last built that system so I figured it was time to step it up. I also use the Creative Cloud often and my system could use a boost in speed. Plus the old components are now in a second tower and being used for offloading things to free up this computer for recording (such as rendering video, etc).

I plan to add 32GB more to the RAM over the next two months and a new 1080ti video card. Someone also told me adding an internal Soundcard might help as well, although I don't see what it has to do with this latency issue.

Thanks again,

Brad
