Windows 10: Having High DPC Latency From storport.sys and ndis.sys

Hi thereFor a while now I have noticed when I'm playing games I receive audio dropouts followed by freezes at a significant regularity. I have recently downloaded LatencyMon and it appears it is coming from storport.sys and ndis.sys. I have researched for hours trying to solve this but I can't quite figure it out. I saw another thread similar to my issue, but their fix didn't help me at at. I'm starting to think it is an issue with my hard drive, but I would like to check and verify before dumping hundreds of dollars. It also might be important to note that I did build this computer.I'm really

DPC Latency with Storport.sys and Wdf0 1000.sys

I have one Storage Controller here is what the Drivers say

The power settings look good, but I would disable the selective suspend on the USB ports, since you have a USB audio driver.

This is not the problem, though. Anything that takes more than a fraction of a millisecond as a DPC process might cause an audio dropout or glitch.

Your values for StorPort.sys are off the wall! That is the Microsoft SCSI driver for your hard drives and SCSI attached stuff.

You might have misconfigured some drive setting (like not using AHCI). Perhaps this is a BIOS setting. Are your SCSI drives using IDE or something like that?

For comparison, I use high end audio stuff on a daily basis and my system was built in 2011.

Here is what I see on latencymon:

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,
