- Gigabit Ethernet cable connected
- Wireless mouse and keyboard receiver connected to the dock
- DisplayLinkManager v. 7.3.49122.0


Some observations (I didn't bother read through all of the posts in the thread so sorry if there are some duplicates):
- DisplayLinkManager eats up ~20% CPU (seems mostly kernel time)
- Updated driver doesn't seem to help at all
- lag is gone if I connect mouse / keyboard receiver directly to the laptop (not through the dock)
<SNIP>

Then the problem is nothing to do with DisplayLink, but USB interference as covered here:
