Windows 10: 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

High DPC Latency caused by wdf01000.sys

Hello,

I am posting this regarding a problem that I ran across in my laptop at the beginning of august 2019, the problem is that I am getting high DPC Latency levels that are apparently caused by wdf01000.sys according to the latency checking
program, latencymon.

I really want to know if there is a fix since I have browsed a wide range of sites trying to find a fix, I could not find any. And also my keyboard stopped working for some reason, if its ok I would like to find a fix for that, but
I prioritize fixing the high latency over the keyboard.

Thank you for taking your time to read this.
