  1. storport.sys driver high latency audio/video slutter


    Hi.


    I experience this issue for about a year now. Finally, I made a DPC latencytest and found out about high storport.sys latency that might be causing slutter video and audio for about a second every 20-40 mins.


    How can I solve this?

  2. 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

    DPC Latency with Storport.sys and Wdf0 1000.sys

    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:
