Good Morning all, I've been playing around with my new copy of Carrara 7 (via 3dArtist magazine) and have run into a bit of a snag. I'm working on a figure render and all of a sudden whenever I maneuver in the Assembly room (pan, rotate, zoom), the cpu usage spikes to 100%, causing a minor pause after each operation.

This in and of itself would not be such a big deal (inured by years of Poser use), but the real problem occurs whenever I try to manipulate the figure itself. Rotating a shoulder for instance, causes the same spike, but it lasts much longer, so long in fact that real-time feedback on posing the figure is impossible.

My own troubleshooting leads me to believe that this is related to either my once having had a particle system in the scene (since deleted, playback set to 0) or that I'm saving textures in-scene, but I can't be sure. Needless to say some outside insight would be most appreciated.

Scene Specs:
Medium Size
4 Lights: 3 spots, 1 distant
One Figure: V4(morphs++, utopia, elite skin shader) with prop hair

System Specs:
Quad Core i5 2.43ghz
4gb RAM
GTS 260 w/512mb
