High CPU Utilization on Windows Devices Post Display Link Driver Installation

[Wim]

Hi

CPU will be used when something changes on the screen. If you have high CPU being used by DisplayLink, then there must be something open that keeps causing screen updates. The CPU should be around zero if you're just showing the Windows desktop.

The intermittent wireless issue is a different problem and probably caused by USB 3.0 interference as covered in this article.

The same happens in this issue: http://www.displaylink.org/forum/showthread.php?t=64887

High CPU with lots of screen changes. One example is video where a modern, fast i7U can't keep up with the CPU load the driver is generating in the system.
If this is "working as intended", then DisplayLink is unsuitable for video playback.
