Fix the problem where DisplayLinkUserAgent eats 38% of my CPU

OS is windows 10, DLUA is 7.9.6.30.0. This often gets in a state where the user agent sets there using between 35 and 38% of CPU.

        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.

        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...

        Same issue here. Windows 10 and DisplayLink 8.1.843.0 (dlidusb.dll). Just moving the mouse generates load on WUDFHost process (Windows Driver Foundation -User-mode Driver Framework Host Process. Are you working on a solution?

        Also seeing this issue with my Surface Book together with a Toshiba dynaDock U3. The surface is on latest Win10 1607 and the driver I currently have installed is 8.1 M0 as of Dec 18th (8.1.843.0)

        I am having an issue with HPElitebook 820G3 model and I am using Targus ACP71EU

        Would it be possible to get a patch so that the CPU does not go high and in my case it jumps to 80% constant UP and down, which is a nightmare for any developer machine.

        Thanks in anticipation

        Experiencing similarissue with Dell Latitude E6440, Win7, while connected to Dell 3100 USB dock. DisplayLink User Agent is using between 30 and 40% CPU. I installed 8.1MO and the issue persists. Thank you.

      • Simon commented  ·   ·  Flag as inappropriate

        DisplayLink STILL haven't fixed this? It's been years

        What is the latest recommendation? Other than buy different hardware

      • Ted commented  ·   ·  Flag as inappropriate

        Why is the agent jumping from 2-3% CPU to 25% CPU or higher and not releasing. I am forced to stop the service and restart and that usually fixes it until the next time it jumps to 25% or higher. I have Windows 7 Dell 7450 i7. I have replaced by machine twice. My dual monitors and my Dell D3100 dockingstation twice. Not sure why me or what is happening specifically. I am using version 8.1.848.0.

        Please advise.
