The displaylink process only shows 5-15%, however if you look at your overall CPU usage while resizing a window you can see it jump significantly which doesn't happen when it isn't docked. I've installed all of the latest drivers/firmware. I even went as far as using some little "hack" I found on a forum to get the Intel USB 3.0 drivers installed on my Lenovo with Windows 8.

There is some info on Intel's website about forcing USB 3 support in the BIOS if you have problems with devices running at USB 2.0 speeds. The Lenovo has an option for USB 3 in the bios which is "Auto, Enabled, Disabled" and 'Auto' is default. You could try setting it to Enable which forces USB 3.0 mode. |
