I've just started using Daz studio, and have read about some of the problems with render times, but the problem I have is with scene loading times. A scene with 4 characters and a few props can take up to 30 min. to load. My PC is not state of the art but is not that old ( 3Ghz / 1 Gbyte RAM)

Has anyone any suggests for reducing load times?
 

Unfortunely this is the result of the way DAZ chooses to save scene data.  Instead of saving to 1 file Studio divides things into folders and sub-folders writen to the "data" folder.  In someways  this approach has benefits in that it can save disc space.  For example any scene that uses Victoria 3 saves her info to the same Victoria 3 folder and sub-folders.  This is true for all models used in any scene, since a lot of the same models get used over and over it can save a lot of space if you are the type that keeps your scenes for long periods or just make a lot variations.  Of course along with making load times (and the initual save slow) it complicates archiving a specific scene since you have to back-up the all the neccessary folder/sub-folder in the "data" folder (not to mention rounding up all the texture files).

I thought something like that was goiing on;. thanks for confirming it. I'll have to live with it until I can upgrade to a faster processor and hard drives

Actually it doesn't save disc space - that's more the eefect of Poser's PMD system. What it saves is memory as only the parts that are needed (in particular, morphs with non-zero values) have to be loaded.
