Windows 10: ACPY.sys having a LOT of latency

Hello.Yesterday i installed LatencyMon a tool to observe and check which drivers/stuff generates hard pagefaults and have a high DPC time, and after a lot of research, it came out that one of the mayor DPC time issues causing a lot of latency, is a process called "ACPY.sys", having the whopping amount of 10,6 execution time. I searched everywhere about how reduce that value, but i didnt found anything that had an actual impact. I tried disabling the Microsoft ACPI battery thing form the device manager and disabling drivers that i dont use such as wireless speaker that i never actually use

:)

 

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

 

Sound stuttering and high latency from Wdf01000.sys and ACPI.sys






Unfortunately updating logitech software did not help.

So is there any way to find out which program or hardware uses that Wdf01000?

 

Wdf01000.sys Latency - Windows 10

Hi,

Wdf01000.sys is a Microsoft driver file. The wdf01000.sys
process should not be deleted or prevented from loading each time Windows loads.

We would like to know more about your wdf01000.sys and latency concern:

• Were you getting errors with wdf01000.sys? If yes, Can you send us a screenshot?
• Which program or application were you using in audio recording?
• What equipment or devices were connected to your PC when you were recording audio?

In the meantime, check out this article for tips on how to improve
PC performance.

Looking forward to your response.
