CPU Usage - Windows Driver Foundation
 
Hello,

I have purchased following product:
-> https://i-tec.cz/en/produkt/u3hdmidvidock-2/

I am using this on my Microsoft Surface Pro 3 (i7 processor). I have only 2 monitors connected on Docking USB Station (over USB 3.0 port). When I am browsing and doing basic stuff, following process is causing high CPU Usage:
-> Windows Driver Foundation

This process is only there when I connect Docking station to my Surface. I have read a lot about this issue, and I have done everything like advised on DisplayLink website and forum, but it is still consuming 20-40% CPU when I am browsing or reading PDF files. I think that this is not normal. My surface is up-to date with all Windows updates and also drivers are the latest.

DisplayLink Manager Version: 9.0.1809.0
Windows 10 64bit Pro (Version 1809 / 17763.292)


Please give me info, what I can do, so I will have better performance on my Surface with Docking (2 Monitors).

Hi, I do have same issue with my D3100 docking station.
Just on moving mouse I'm getting higher CPU usage, and I'm getting my CPU fan start spinning. While doing just basic things, browsing, reading documents, working in MS Office. I'm using two monitors also.
When my laptop is not connected to the D3100, no issues.

My configuration is:
1. Laptop HP Pavillion 17"
2. Intel i7 - 6700HQ
3. Windows 10 x64 1809, release date November 13.2018
4. Dell D3100 docking station
5. DisplayLink 9.0.1809.0
6. Connected via USB 3 port

Thanks

I still have the same issues, even with the latest version of DisplayLink. Is there any solution on this?

I got another laptop with previous Windows 10 v1703 and I could see that Windows Driver Foundation CPU usage is ramping up from time to time, when there is activity with the mouse or keyboard, but no CPU fan increase. This has been verified on HP ZBook 15 G3 laptops.

At the same time, my HP Pavillion AB067 is having the same CPU usage on Windows Driver Foundation, but CPU fan is almost constantly on. When there is no activity with the mouse CPU fan goes off. I can't distinguish is it only a mouse or processes in general.

I'll have to reinstall Windows and downgrade to 1803 and then to 1703 versions to see if this will make any difference in CPU and fan usage.

OK, I did couple of tests...

1.Installed Windows 10 v1809 and DisplayLink 9.1 M1
Latest Windows 10 v1809 updates. All drivers updated, all Microsoft store apps updated.
Result: Often high Windows Driver Foundation triggers CPU fan to spin all the time

2.Installed Windows 10 v1803 and DisplayLink 9.1 M1
Windows 10 v1803 updates. All drivers updated, all Microsoft store apps updated.
Result: Often high Windows Driver Foundation triggers CPU fan to spin all the time

3.Installed Windows 10 v1709 and DisplayLink 9.1 M1
Windows 10 v1709 disabled updates. All drivers updated, all Microsoft store apps updated.
Result: Windows Driver Foundation normal CPU usage, CPU fan starts spinning in high demands only.

4.Installed Windows 10 v1703 and DisplayLink 9.1 M1
Windows 10 v1703 disabled updates. All drivers updated, all Microsoft store apps updated.
Result: Windows Driver Foundation normal CPU usage, CPU fan starts spinning in high demands only.

CONCLUSION:
DisplayLink drivers are not compatible with latest Windows 1803/1809 or any newer releases.
If you use any of the previous releases without latest updates, DisplayLink will work just fine.

DisplayLink Engineers should initiate dialog with Microsoft engineers to resolve this issue.

Our Windows machines are vulnerable due to missing updates but right now for me it is more important to reduce CPU fan speed and noise than to have latest and greatest Windows updated versions.

Another test:
1. Windows 10 1709 with DisplayLink 8.5.3459.0 is working just fine.
2. Windows 10 1809 with DisplayLink 8.5.3459.0 has issues with WUDFHost and CPU and CPU fan usage.

After two days of testing several releases of Windows and DisplayLink drivers, it is obvious that DisplayLink is not compatible with any Windows releases after 1709.

Hello,
I have same problem with DisplayLink (High CPU and GPU usage). Attached zip file contains more information about my setup (created by DisplayLink Windows Support Tool 1.0.1.31).

Hello,

I have created a case to look into that.

It is wrong to claim you are less secure. Security updates and feature updates on Windows 10 are separate. Both Windows 10 v1803 and v1809 are still in support. The most recent Windows 10 v1903 is only starting to deploy now.

I've left Windows Update running, and I got Windows 1703 updated to 1803 version automatically by Windows Update.
Therefore WUDFHost start utilizing CPU fan again. I've decided to install DisplayLink USB Graphics Software for Windows ALPHA 9.2 Alpha just to verify whats going on.
This time again same issue.

I have attached ZIP file from Diagnostic tool.
