It shouldn't peg the CPU, I specifically made changes so that it wouldn't.

Let me be a bit more clear about that...

If you've got the "face" screen showing that actually has the images of the screen updating constantly, then face.exe will be near the top of the list of tasks when sorted by CPU. But that's only because it's the only app really doing anything. Start another process doing something that needs CPU time, and the other process will take over.

At least that's how it should work.

If you don't want it to use up CPU time at all, minimize it or hide the face and only show the remote.
