Yo Rod, I have exactly the same problem, and I've mentioned it to Curious repeatedly over the months, but they seem to want to act like there are no problems at all. It's infuriating because we all know that the program starts screaming as soon as you load a couple of high-res models with textures. Here's their latest response to my request. I found it pretty perfunctory - verging on patronising, but there's just the tiniest chance that there's something hewre that might help you... If you do come up with a solution, please mail me. > Hiya, > > I have Poser 4 and the Pro pack running on an Athlon 1.2 with 256MB of > memory and plenty of hard drive space. > > The program slows down to a crawl as soon as I add a couple of characters, > but if I import a 3D prop such as the Daz rowing boat, the program can > grind to an absolute halt.

RUN A FULL SYSTEM DIAGNOSTIC AND BE SURE TO CHECK YOUR RAM. WE HAVE HAD REPORTS OF BAD RAM WITH P4/ATHLON MACHINES. ALSO RUN DEFRAG, SCANDISK, VIRUS CHECKS, ETC. YOU CAN ALSO: - DOWNLOAD LATEST QUICKTIME - INSTALL LATEST VIDEO DRIVERS - INSTALL OS PATCHES - ALLOCATE MORE SYSTEM RAM PER YOUR OS INSTRUCTIONS (START>SETTINGS>CONTROL PANEL>SYSTEM) - IF ALL ELSE FAILS, BACKUP CUSTOM CONTENT, COMPLETELY REMOVE AND REINSTALL POSER AS FOLLOWS: * WITHOUT PRO PACK: POSER 4 POSER 4.03 UPDATER * WITH PRO PACK POSER 4 PRO PACK PRO PACK SR-2 (DO NOT INSTALL ANY OTHER UPDATERS/PATCHES) ALSO, WHICH CHARACTERS ARE YOU USING? DOES THIS PROBLEM OCCUR WITH ALL FILES OR JUST A FEW? IF IT OCCURS WITH ONLY SOME ITEMS, THEN THOSE ITEMS ARE PROBABLY THE ISSUE AND YOU SHOULD CONTACT THE SOURCE WHERE YOU OBTAINED THEM. > Poser seems to handle resources extremely badly, and does not appear to be > fully releasing memory after characters have been deleted. DEFINITE CASES OF POOR POSER RESOURCE USE HAS NOT BEEN REPORTED AS AN ISSUE EITHER BY OUR QA PEOPLE OR BY USERS. (Ha ha ha ha - my comment!!!) WE HAVE SEEN RAM ISSUES WITH 1GHZ MACHINES AS THE MAIN CULPRIT SO FAR. > I assume it doesn't use Direct 3D or Open GL which could have made a big > difference. LACK OF ACCELERATION IS CLEARLY SLOWER YET ALSO MORE RELIABLE IN SOME WAYS. > Are there any techniques for releasing memory back to the system, or > improving general system performance? PLEASE REFER TO YOUR OS DOCUMENTATION.
