A couple of other things to report:

"Cancelling" is way way more responsive.
Cloth room sim working fine
Dynamic Hair sim WITH COLLISION is vastly better.

Moving from room to room is very glitchy, inclucing crash to desktop, if you have a floating preview window.

I gave up trying to add my Poser 7 runtime as a library. It 'worked' in that the folder was found, but only a few items show up!

Tried adding a mirror to my scene, reflection shaders apparently not a friend of the Poser8GI, it just slammed to a halt.
