PeterWahoo I only got my faster computer a couple of weeks ago, and am just now getting P5 set up on it. Before that I was using a 733MHz P3 with Poser 5 and it worked fine. The only things that really slow it down are dynamic hair and dynamic cloth. If you stay away from those and set your render options carefully, it can render even FASTER than Poser 4. Those people who complain about the speed of P5 just don't know how to use it properly or they would be singing it's praises. If is unfair to compare render speeds of Poser 5 Firefly to Poser 4 because they are totally different types of render engines. If you want FAIR comparisons, then compare P5 firefly render times with Bryce or Vue (because it is more like them than it is like P4). Then you will be shouting about how amazingly FAST Poser 5 is!
