Windows 10: DPC latency diagnosis - nvlddmkm.sys, dxgkrnl.sys, wdf0100.sys etc

Hi there,

Need a little guidance around how to use Windows Performance Analyzer to diagnose my DPC latency issues. I've run the recorder, but unsure which items to "graph" and then drill down to. I've seen screenshots from others posted here which show apps and their relationship to processes - such as wdf01000.sys, dxgkrnl.sys and so on.

My latency issues are moderate, but I'm running a high end external sound card for audio production and in my former Windows 7 environment I had latency down super low. It's occasionally peaking at 2600 which is really not suitable for audio production.

Cheers,
Davros

Like this? It appears "Standard SATA AHCI Controller"

I have one Storage Controller here is what the Drivers say

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
