I would call this a bit extreme CPU usage.

System:

Linux xxx 4.8.0-26-generic #28-Ubuntu SMP Tue Oct 18 14:39:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 16.10
Latitude E6540
Installed version from displaylink-driver-1.2.65.run

Adaptor:
Bus 004 Device 003: ID 17e9:4324 DisplayLink

CPU load sometimes drops to low 70s, still less than ideal.
I can provide you with any logs you need, we can chat as well on anything that's convenient for you.
