I wanted to chime in here. This thread is only a few days old, so I hope it will still get read. :-) I'm having the same problem, especially with high res textures. I have a 1.4Ghz Athlon with 512MB of PC133 SDRAM. I have virtual memory set manualy, with 1024kb reserved. My swap file is regularly defraged and is placed on the fastest section of the hard drive plater. I've been trying to render the Asia texture by StefyZZ, have more than the minimum hardware and memory requirements, but it locks up every time. :-( I have to reboot to try again. What is very strange is that FreeMemPro reports I still have over 256MB of ram free when Poser locks up, plus I know I have plenty of virtual memory. I found it interesting in the reply from Curious Labs above that they state: "WE HAVE SEEN RAM ISSUES WITH 1GHZ MACHINES AS THE MAIN CULPRIT SO FAR". (Their caps, not mine. BTW, funny that this statement comes right below the one where they claim they haven't logged reports of such a problem)! Could it be that the 1Ghz and up machines are doing something too fast? Either in Poser, where some part of the render set up that has to happen after something else doesn't have a WAIT programed in, because pre-1Ghz, it would never finish pre-maturely; or, some problem with the way Windows manages memory with fast machines? I don't have any other software that has a problem with my current set-up... BTW, yes, I'm on Windows 98 SE. I'm glad that Windows 2000 seems to help a lot, but not sure I want to upgrade just for poser, espescially with Windows XP due in October. Does anyone else have any solutions that have worked for them? Maybe we should start a petition to demand a fix from Curios Labs! BTW, I used to use custom high res textures before updating Poser to the Curious Lab's version 4.03, so it must be related to something in the update that they changed?
