When I first started this post, I thought maybe there was a rhyme or reason to why some have good luck (or relatively good luck) with Poser 5 and others don't. I figured: "Must be an OS/Computer specs issue". But reading through these threads and then noting a post by a user at the SR3 post, it doesn't appear that it makes a damned bit of difference! The success or failure of use with this software appears to be total random where hardware and OS are concerned....although it is clear that the majority of those who actually posted here use some version of XP or Win 2000. I suspect that's because the NT based machines handle memory better than the 9x series. Also most of you have a lot of Ram and a large processor (much larger in both instances than the recommended amounts on the box!) Not sure video cards matter much with Poser 5. I don't believe the rendering engine uses hardware acceleration, does it??? Someone correct me if I'm wrong. A lot of you are using GE Force cards of one type or another, but not all of you. Queri's situation comes closest to mine in terms of issues, although her machine is a bit more robust than mine (1.7ghz processor, 512 mb ram, Pentium IV and XP Pro. NVIDIA GeForce 2MX 100/200 graphics card.) There also seems to be some commonality in the issues addressed, where "issues" do exist. The rendering, texture loading, slowness, etc. My problems have been very similar to those described here and like many of you, I take care to maintain the machine regularly and very carefully read the instructions before installing the patches. I've not had the install problems that I've read a lot of places (although I have not and probably will not, install SR3). Thanks to all who took the time to respond. Not sure what this all proves, but hopefully CL will read through it and learn a bit more about the common issues that those who have pretty good luck with Poser 5 (myself included, I guess), are having. Maybe that's where they need to start! :)
