Yes, I noticed that too. It's the graphics engine, I guess; P8 behaves (for me at least) with one figure like P6 does when you have 4-5 fully clothed figures in your scene. Reactions are slower, optical feedback is spotty, so one tends to overdial. Everything moves by uncontrolled jerks, which can be a real pain in the neck when working on complicated scenes, and a real shopstopper when working on bigger ones. I still use P6 for posing, for this reason.

I sure hope SM will optimize this for SR2, or at least add the P6 preview engine as an option (I really don't see what the P8 one does better than the old P6 one).
