High CPU usage when doing camera orbit.

High CPU usage when doing camera orbit.
UPDATE: Just moving the mouse will make CPU usage shoot through the roof. It does not have to be in camera orbit mode.

Originally, I thought this issue was caused by my mouse, but it is a CPU load issue.

When I orbit my scene (middle click mouse button) then as I move my mouse, I see my CPU load shoot up, exceeding 100% for beam.smp

As I halt my movements (while remaining in the orbit mode) the CPU load drops to 0, and it shoots up again, as I start moving my mouse again.

This video shows the issue (with the high load from the desktop capture, beam.smp stays at 80% or so in this video, but I've seen it go 100+ without the desktop capture. And it goes to 0 if I stop moving my mouse.)
