8.1 release has started to bring improvements, 8.2 continued to build on this.

Probably the last update. Since the 8.0 M2 Driver Version, it feels much better and I was not able to see that high CPU utilization of the WUDFHost.exe again so far :-)

I´ve seen that you just released 8.0M2. I installed it and it feels much better. I´ll work with it for a day and then Report back.
Please don´t Forget to update the Corporate installers (they are 8.0M1 at the Moment), so I can update all my OSD Tasks :-)René Büdinger

To add to this, I experienced very high CPU utilization of the wudfhost.exe while doing a Download a few minutes ago (downloading with around 8 Mbit/s) and the mouse lag was very, very bad. Using Process Explorer and having a deeper look at the wudfhost.exe, I could spot the dlidcore.dll always on top and consuming most of the CPU cycles. Dlidcore..dll seems to be part of the DisplayLink Drivers. Those new Drivers (or the new Driver model) seem to have issues. At least on a Surface Pro 3, so maybe it´s just with some chipsets? Now as the download is finished, CPU utilization of the wudfhost.exe went down to around 20% and mouse lag is much better (not gone, but I hit the spots I want to hit again).
Despite the huge CPU utilization, is it possible that the older Drivers had a better queueing and favoring mouse Input before everything else to have a better Input experience?René Büdinger

It´s much better since the M2 Driver update. But occasionally the wudfhost.exe (and its subcomponent, one of the DisplayLink Drivers) start to consume 1 processor core and the lag is really horrible. This goes away after a reboot or, if I am patient enough, sometimes after an hour or so. Since there´s also a huge thread on the Display Link Forum (I only discovered after I had found this Feature Suggestion website), I´m following the progress there instead. Thanks for reading and replying to my post :-)
