Jody, I understand what you are saying. When I say peaks at 50%, I refer to while rendering, and my system is kinda hanging out, I can see my CPU measure for the Poser.exe process hit 50% and stay there until my render finishes. If System Idle is the next biggest process at say 45%, that just seemed wrong to me. Especially since my nifty nVidia card does absolutely nothing for Poser and Poser relies totally on my processor. Ah, well. Thanks for all the comments! Shogakusha
