I have the high CPU load issue with Windows Driver Foundation when docked in the Displaylink dock, simply moving the external mouse causes the cpu to spike and lag, when undocked from the displaylink dock (thinkpad) everything is normal and no spiking of cpu,
this is frustrating, i've tried every driver released for this and still the issue persists, as this is occuring on several hardware vendors you cannot blame the manufacturer of the computer, the computer i'm using in this case is a Surface Pro 4, please fix this annoying problem thanks |

The same issue here with a Dell XPS 13 9360 and a Targus Dock with an external monitor.
WUDFHost.exe consuming always some CPU, monitors lagging, etc. I hope a fix is available soon. |

Got the same issue here with the Anniversary update and WUDFHost.exe, specifically the process loading the Intel 520 driver dll's.
Updated the Intel drivers to 21.20.16.4574 and the DisplayLink to 8.1.843.0 but still getting the problem. It's actually making Edge unusable. This is on a Dell Latitude E5470 and a Targus ACP71EU dock. |

Same issue with Windows Driver Foundation hogging the CPU. Latest displaylink driver just installed. Running 2 external screens with Lenovo Yoga 3 (i7 5500U + 8GB ram).
Can we have an update on expected next step and timeframe to solve this? |

Hello,
I have been notified that engineering has now been able to reliably reproduce it on a model of machine. They are now working on understanding the problem. There are a few leads they are following, one of them is linked with memory. Result of the investigation will be telling what will help and a timeline. If I understand that 50% CPU is considered high, having 5% would leave still 95% free... If a computer is struggling with 5% CPU usage, then there is something else at play! Unfortunately the system gauge doesn't give any obvious information about where the bottleneck is. WUDFHost, as its name indicates is a process hosting other processes (Windows User Mode Driver Framework). One of the hosted processes is the DisplayLink Manager process. This has changed from a separate DisplayLink User Agent, DisplayLink Manager approach because we are now using the Microsoft standard USB driver. Kind regards, Alban

I too have the problem
I don't use the display connections on my dock at the moment, just the ethernet and usb ports.
When using SysInternals procmon to see what WUDFHost.exe is doing, I see that it repeatedly accesses the registry key HKLM\SOFTWARE\DisplayLink\NivoManager. |

If you don't use the video, then a high load would have a different reason. What is high? Ethernet and audio are also going through the same physical DisplayLink chip. Also, whether you use a video output or not, the chip is on the USB so Windows will talk to it. Kind regards, Alban

Hello, I have the same problem.
I can't use my four USB screens. I have update my computer with the last nvidia driver, and my problem is unchanged. I work in the development of flight simulator, and it's logical for us to simulate any instruments between different screens. And the top for a good interface utilisation, is the possibility to change rapidely by USB ports of screens. I try to disconnect GPU / Graphic Card / Wudfsvc, but nothing happens. My only option for the moment, is to remove physicaly one of the twice graphic card from my motherboard, for have 3 surround screens HDMI, and four USB sreens for plane instruments. It's not envisageable.... . The computer is very powerful : OS : Windows 10 / version : 1607 / 14393.693 Proc : Intel i7-6700K RAM : 64 Go System : 64 bits processor x64 GPU : 2 X GTX Geforce Titan X SLI Motherboard : Asus Maximus VIII Extreme Sceens : 3 screens HDMI 1 screen VGA 4 screens USB Lilliput Drivers Nvidia version : 378.49 Drivers DisplayLink : 8.1 M0 Can you give me a configuration tip? Or tell me if the next DisplayLink drivers will solve this compatibility problem? and when ? Thank you Best regards, Markus Last edited by -=Markus=-; 01-25-2017 at 11:15 AM. |

I can also reproduce in my system: Dell XPS 13 + Win 10 + 2 External monitors attached to a Targus doc. As soon as I start using my external monitors, the issue happens. Very annoying.
