Fix the problem where DisplayLinkUserAgent eats 38% of my CPU
OS is windows 10, DLUA is 188.8.131.52.0. This often gets in a state where the user agent sets there using between 35 and 38% of CPU.
7.9 M5 release for Windows is now available from our download area. Please create a support ticket for individual investigation if you meet any issue.
I'm having the same issue. Windows 7. Driver version 8.2.1646. Whenever I dare unplug my dock, the DisplayLinkUserAgent completely pegs a core. It makes my mouse freeze up, as others have stated, and my laptop becomes nearly unusable. I don't have admin rights on my work laptop, so I have to reboot and start up all of my apps again.
Windows 7 pro on a Lenovo T430 . Recently upgraded and got complaint about USB3 driver incompatibility. When watching YouTube CPU goes wild and DisplayLinkUserAgent generates 50K Page Faults per second. Constraining the processes to one core and running a simple CPU hog on the same core at a lower priority reduced CPU load to about 10%. Total memory usage stays under 100 MB.
We did notice here that if you move all your files from your desktop to elsewhere else, the CPU usage returns to normal... then, if you move back the files, it stills ok.
I hate IT
Seems to be related to what is actually being rendered. I only get massive CPUs spikes when watching videos.
Problem still present with newest driver version 8.4 (pre-production)
Problem with 100% CPU is absolutely clearly related to network DisplayLink. Plug in and have 100% CPU, disconnect and CPU goes back to normal. Need urgently a solution as otherwise no monitor is available.
I had the same problem - stopped using my dock entirely. Today I installed the latest driver (December 1, 2017) from the link provided by Alban Rampon above and it worked. It is tagged as "Not for Production," so I was a little concerned. But so far, so good!

Burning over 100% of CPu on High Sierra (on Mac Air). We need a fix
Same issue in high sierra for me also, CPU is running 100%+ on display link manager
Im also running high sierra, and same as the post before me, displaylink manager takes up all cpu. internal fan cant even cope
Same issue on High Sierra, it is brutally taking 98% of the CPU. Crazy.

Just noticed when connected to a usb-c dock with display link (on the latest driver 85514) on my mac book pro 15" 2,6 GHz Intel Core i7 it eats away 600% of processor resources when videoconferencing. 6/8 cores. That's some performance. We were about to order a few hundred docking stations for our meetingrooms. I ordered an investigation to see where to go now.

I have been trying to find a solution to this for 9 months...how long can it take?

CPU usage goes up to 50% when XPS13 connected to Dell D3000 docking station.
runs fine with D3000 disconnected. installed latest Displaylink driver but no luck of fix.

DisplayLinkMana uses 100% of a core on a Dell XPS 15 running ubununtu 16.04 with version 1.3.54
CPU hogging for MacOS/Sierra as well for me. taking between 12 and 30% of my CPU on i7/2.7GHz
This seems to be a new-ish problem for me in the past few weeks.

Same issue here on MacOS with Sierra
September 2017, still no fix for the high WUDFHost process load when using displays over DisplayLink. Video playback is choppy and the systes gets crippled from the CPU load.
Why isn't this fixed yet? This should be a priority
I have an HP comaq (not sure what exact model) with an ASUS Nividia GeForce 210 silent video card and two monitors hooked up to the VGA and the DVI inputs on the card. do i need DisplayLink if i'm not using a USB cable to connect my monitors?
same issue here...Systems run on Win 10 professional with DisplayLink 8.1.843.0. As soon as you move your mouse from the internal display to the external display/s that are connected to the usb3 dockingstation the CPU usage on process "WUDFHost process (Windows Driver Foundation -User-mode Driver Framework Host Process)" gets to 20%-80% and the mouse movement is "lagging" hard -> working is not possible (even the i7-6700HQ cant handle the CPU usage of the above mentioned process).
I´ve tried to install 8.2 Beta 2 08 Mar 2017 to resolve the issue but the problems still exists.
The newest graphics card driver from Nvidia (from 09.03.17) and chipset drivers are up to date.
Problem occures on every type of notebook (Dell XPS, Schenker XMG and Lenovo Thinkpad).
Hopefully this issue gets resolves soon or maybe someone finds the cause and a possible workaround for this issue...
DisplayLinkUserAgent does not exist on Windows 10 Anniversary Update onwards (v1607).
