High CPU usage
 
Greetings,

I have the Plugable UD6950H dock which requires DisplayLink.

DisplayLink Driver version 9.2.2420.0
WIndows 10 Home
Version 2004
OS Build 19041.508
Date: 20200723

This issue does not occur before 08/20/2020.

My CPU usage is between 30-60% constantly while I have the DisplayLink running. Windows Foundation processes seem to be common in thread.

Is there a fix for this?

hey wolfrhogan,

What's your system setup/specs?

I used to have the issue, but after deep troubleshooting I found out that the issue was being caused by glitches -- more or less -- in the software being run while connected.

High CPU usage
 
I have same problem. Definitely the Display link driver and Windows 10 home 1903 and I can't get the next version of Windows because I have Conexant audio driver that is a known issue. Wish it was listed that Display link is a known issue.

I have the same problem. I use Dell D3100 USB 3.0 docking station and 3 display (3 x Philips 24 FullHd). I have cpu usage about 30-40% by Windows Driver Foudation process.
OS: Windows 10 Pro 20H2.
My computer: HP Elitbook 8570w - cpu i7-3720QM

it's been YEARS
 
2018, 2019, 2020, 2021... how many YEARS until this gets fixed?! Would a class action lawsuit help speed things up?

Same on Windows and Linux
 
I see this is still not fixed. I just updated the driver on Linux and it still has high cpu load.
Even when the monitor is doing nothing, just displaying a still image, I already have 16%. Just moving the mouse on the monitor increases the load to 40-60%.
Watching Youtube increases it beyond 100% and the fan turns on.

I have a Lenovo with Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz and 16 GB RAM with an USB-C Lenovo Docking Station

This is the same on Linux AND Windows! Just under Linux watching Youtube on anything connected to the Displaylink device sometimes freezes the Screen and I have to restart.
When I watch Youtube on the build in screen, I don't get 100% CPU nor a running fan.

Why is this so bad?

Going to give this a bump.

The high CPU usage still exists. The only reason why I can "tolerate" it is that my computer's hardware is just that powerful and I don't notice a degrade in performance.

Here's my setup/specs

Ryzen 9 5900HX with Radeon Graphics

Nvidia GeForce 3070 dedicated GPU

32 GB RAM.

The display link dock is the plugable UD 6950Z - connected via USB 3.2 type C.

I have the power management set to not turn off the connection.

The USB selective suspend setting is set to disabled and the USB 3 Link Power Management is set to off.

I don't really notice anything but a brief performance drop and I have to believe that this due to the integrated GPU with the CPU spiking usage.

I'm running Windows 10 Home version 21H2 but it was also happening on 21H1 and earlier.

I bought an ICY BOX USB 3.0 & USB-C Docking Station a week ago and ever since I started using it with 2 monitors I'm getting 100% CPU usage all the time. My Lenovo is 1 year old, 16GB memory, I'm getting 34GB to see if makes any difference otherwise I'll return the docking station.

This problem started for me about a month ago, I have 3 laptops that all share the same dock with a KM switch. Until late last week only 1 laptop was having this issue and now all 3 are.

I haven't been able to narrow down the issue to a specific Windows update but that's the avenue I'm currently looking into.

Ok, so this has really become and issue and a personal mission to find either a solution or at the very least something that's a contributor.

After doing some additional searches I came across some other folks that were having issues with hardware acceleration in Chrome. The more tabs they had open the quicker the issue would manifest itself. So I decided to see if that could be replicated and for the most part yes, having a couple Chrome tabs open certainly caused the issue to happen less often, but even with all Chrome processes stopped the performance was still high on this process.

The next thing I noticed was that my Intel Iris Graphics would top out at 100% and then my displays would crash. This lead me to another thread where a Displaylink Vendor posted April 2021 that Version 30.X of the Intel Iris Drivers were having issues with their hardware and they recommended rolling back that driver.

I did that this morning and so far I have been 45+ minutes without issue. I'll continue to monitor and see if it returns but hopefully this will help other folks.
