Bryce 5 renders even slower than Bryce 4. However, I guess I will just use it for final renders...and adding some special stuff at the end. I do seem to notice a nice quality on the b 5 renders. I also do like the render percentage being shown at the bottom of my screen. I can leave, do other things, and not run into having a render pick up the "on screen" image, if i am off wandering.
