Anyone who is contemplating P5 should read the threads here about it. It has problems. It's a memory hog and has (in my opinion) a memory leak. It's really too big a program to run on Win98 effectivly, since Win98 has memory limitations of it's own. It also requires a large swap file to handle files of any size. Many of it's advertised features do not work properly. It's slower than P4. We've had 3 major service releases, and are expecting a 4th. We're not even sure what the 4th service pack will fix (or break). DO NOT BUY P5 IF YOU THINK SR4 WILL SOLVE ALL OF THE P5 PROBLEMS! That said, is you have a big machine and are running Win2K or XP, it's not really that bad. The Firefly engine does some very nice rendering (when it works). The material, cloth, and setup rooms are great. True, face and hair suck, but we can't really expect it to work as advertised, can we?
