I'm using P5. I'ev been fighting it since it first came out. I have all the patches. I have a lot of slowness with it and several crashes that are easily replicated. I have a 1.7Ghtz machine and 1G of RAM. (I upgraded from 512MB recently.) If that isn't good enough machine specs for P5, please let me know what is. For those people who haven't installed it and are trashing it, yes, that's stupid. There are a number of us who are having serious problems with it and it's not due to low-end machines nor user error. Having P5 crash every time there's a texture file it can't find is NOT user error. Some versions of the patch allowed P5 to graceful error out and allow the user to point P5 to the right file. The current version keels over everytime. I'm getting to the point where I have to manually check every file with texture references in a text editor for fear a bad file reference that will crash P5 in the middle of my work. I have to check every light set before I render because P5 can not handle some light sets that work flawlessly in P4 and PPP. It's been documented by many people. That is NOT user error. Yes, there are user errors that are erroneously attributed to P5. Yes, some people don't have a good enough machine. On the other hand, some of us are having a lot of problems and it IS from P5. Please don't lump everyone into the dumb user/bad machine category because it's not true. It's frustrating enough to sit there and wait a while for P5 to switch screens or load libraries, let alone watch it crash because you forgot to check all your lights before rendering. It's incredibly aggravating to then read in the forum how it's obviously all in your head. Thanks.
