AppPolice? Why would it use the GPU? Normally I can have a bunch of
miscellaneous apps running (Mail, Safari, TexEdit, BBEdit, iTunes, and
anything else I happen to have open at the time), with Handbrake running
and encoding pegging all 8 cores at ~100%, and be playing 3D-accelerated
games without any significant stutter on this Mac Pro. When I also run
AppPolice, I get a very noticeable stutter in 3D-accelerated apps.
Without AppPolice running, the weather is clear.
