Quote - 1. I've noticed some talk about P8 rendering faster than PPro, even though 8 doesn't have the 64-bit render engine.

The biggest single improvement is the smarter multiprocessing.  If you have a multi-core machine, on average your renders will complete many times faster, because the old multiprocessing scheme was dumb.

And CPU usage was inefficient. It spent time doing nothing, even when all the threads should had been busy: Poser 7 or Poser Pro rarely used 100% CPU, while P8 goes immediately to 100% CPU usage, and it won't drop before the render is finished. You can say P8 renders really as fast as it can.
