Default 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.

Thought id Quickly jump in

Im using a displaylink d3100 via usb3.0 also and experiencing same sort of issues here.

CPU usage high and Win Driver foundation at it in the background.

The setup iam running is a 7700hq / gtx1060. I do majority cad work and the display link is used as an output for my third monitor.

On bootup it is fine temps are low and normal, however within 10-15 mins of use it gets higher and higher, somewhere between 10-15c more than usual, including on the GTX also. I also look at power draw and its very significant. Now before we go any further, this is a fresh up to date 1903 install hours old.


Ive been using this since 1709 and the temperatures and cpu multiplier rates were never this bad once the drivers are updated or the dock is being used.

Ive been pulling my hair out, tried old drivers, new drivers but nothing. While im using the dock i hit temperatures of 75+ while doing simple autocad saves.

Without the dock plugged in or installed temps drop 30-15 degrees.

So.. Any news? I dont want to get rid of it, its only 11 months old.

Also to add, the laptop is liquid metal cooled and undervolted, before we go down the “your laptop may be at fault route”

After few minutes it is not possible to work with the docking station anymore.
