P8's rendering speed is dramatically faster than Poser Pro, so far I am happy with this edition.

The only crash problem occurs, which I can confirm again and again, is when I put more than two figures (V4 or others) into one rendering scene, an "out of memory" message appears and the program crashes. Afterwards when I restarts Poser 8 and tries to enter "general preferences" setting it crashes again, at the end I have to uninstall Poser 8, remove all previous settings and reinstall again. Back when I was still using Poser Pro I can put in up to 4 Vicky 4 figure into a render scene without crashing, so I think there may be a problem with Poser 8's memory management.
