Ok, I have an NVidia card and XP Home, 2.4GProcessor, 2G memory. All the latest patches from CL--didn't install P5 at all until most of the bugs were supposedly fixed. I havent' done a thing about my Nvidia drivers. I've had two relatively minor crashes with P5-- reported them in beta, they're known, supposedly being worked on. They involve cancelling a render to a larger window. I don't do that anymore. Other than that-- I hate to say it, I have a more stable machine than Pro Pack which always crashed after about 2-3 hours of work for no reason at all. More stable If!!! I don't make my own hair, I haven't tried the clothify room yet, I don't do animations and never will, Haven't used the face room, I'm not impressed with most of what I've seen come out of there. I only use one figure-- will try two but I'm betting one of those will be low res. I have used V3 maxxed out with morphs-- I didn't like how slow it posed, I dropped the morph count in the body, left the head maxed, got back my speed. And this is with dynamic hair-- made by Rdna to render fast and it does. And most of the time I pose with full display. I wanted a better renderer that wouldn't drive me crazy and a chance to use the nested libraries. This is working so far. If only CL had only chosen to do that and the Material room I think we would all have been grateful. I don't want to say it but I will anyway-- my system may be bottom line for Poser 5. Over 2Gprocessor and 1G or more memory. Emily
