I don't understand why everyone thinks that you have to have a supercomputer to run Bryce(although it would be nice!) This may shock many of you , so grab a hold of something! I'm running Bryce on 2 computers, one of them has a Pentium 150 with 80 Megs of RAM. The other has a Celeron 333 with 64 Megs of RAM. I always hear a lot of people complain about the rendering speed of Bryce 5. I've rendered volumetric clouds in an image that was default size (540 x 405) in just over an hour and a half. I don't think that that is too long to wait for an image to render. Like I've heard someone say: "The image will spend more time being finished than it will spend rendering." So have a little patience, it'll finish! I love the program and I haven't had a problem with it yet. I say go for it! ;-)
