Windows 10: Audio and Video Tearing - High DPC Latency in LatencyMon

I'm having some audio and video issues. They're most prevalent while playing games (Warhammer 2 and ESO, mainly) and the issues cause the games to stutter, drop FPS, and the audio becomes corrupted. This also occurs when starting the PC. The audio is corrupted and the mouse cursor jumps a bit.

I'm not sure what I need to post for you to investigate these issues, but let me know and I'll do it.

I noticed, however, dxgkrnl.sys and storport.sys have extraordinarily high DPC latency in LatencyMon.

This is what I've done so far to fix these issues:

* sfc/scannow
* healthcheck
* updated my audio driver
* used DDU in safemode and updated my GPU driver
* updated my chipset
* reset my pc

The following is what I see in LatencyMon. The spikes happen randomly and result in the torn audio and video issues.





I'm lost and I have no idea what to do now. Thanks in advance.

Windows 10 High Dpc Latency

I believe DPC Latency Checker does not support WIN 10. Please try LatencyMon and check.

I had this issue so thought of sharing.

 

Audio stuttering/buzzing and storport.sys high dpc latency

I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
I've already done to avoid repeated answers

I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

I would also like to know if having
Ricoh SD/MMC Host Controller and nothing else aside from that, under
IDE ATA/ATAPI controllers, is okay and won't cause problems?

please, I hope someone can help and answer this time around!

 

DPC Latency while using LatencyMon

which of the DPC Latency issues do you have? Video? Audio? Networking? or all 3? are you sure your using the term "DPC Latency" correctly? Examples of DPC Latency are when video or audio or networking has big slow downs for a second or two then back to normal, like video frame rate drops way down then comes back or audio cuts out momentarily and then back as normal or networking goes into a strange no down or uploading like it froze for a moment....Did you run a DPC Latency bench that said you have issues? Please tell us what is going on with your PC.
