– Does the CPU usage remain high when there are no visible updates in the session?

Yes as long as a connection is established even if idle the cpu is high
– NoMachine product and version on local and remote machine (free version, Workstation, etc).

As stated above the no machine server version is 4.22 installed on xubunutu 14, connection from windows,Mac or linux has the same effect
– Whether the problem arises connecting to a physical or a virtual display.
