Mover Plugin's client-side performance is quite bad

On opening the physics pawn level in the Mover Examples plugin, there is significant client-side lag and glitching. I ensured the settings were correct. The glitches in this recording happen at the “average” network emulation setting.

With the standard movement (non physics) the destructive lag looks like it’s on the other clients.

In each of these cases, changing direction seemed to make the character snap to its predicted position. Is this normal, or am I doing something wrong? Surely it can’t be considered acceptable for a multiplayer game with any latency at all.
