1.) Without Poser5/6's Service Releases installed there are Memory problems! Poser manges your RAM like crap without them! It is crucial you have these installed!

2.) Putting Poser's actual Memory Bugs aside, I'd second guess ever making your Virtual Memory Swap file smaller, especially for a memory issue. In fact I advise the opposite! 4GBs is the maximum Windows will allow you per partition/disk. Virtual Memory is where your computer goes when it runs out of RAM. You can change this setting by going to your Control Panel > System > Advanced > Performance > Advanced.

3.) I have two V3.PZ3s. One is 225MB, because that is where I archive ALL of my MTs. I only use this scene for sculpting. I've gone ahead and recreated the big scene, but then have never Injected all those Morph Targets. After I've used the big scene I export a Morph Target of the work I've done that day, and then import only the newest MT into the smaller 10MB V3.PZ3. The two scenes look exactly alike, but then smaller scene is what I use for rendering, and testing MATs on. The link above is to a python script that is brewing to convert/strip the larger scene into the smaller scene without ever needing to export/import. You should pop your head in and cheer SVDL on, he's bitten off ALOT!

4.) Remember you only need as big a texture as you're planning for your final render. That is if you only plan to render a 1024x768(An average computer monitor resolution) pixel image, then you would never need to use a Hi Resolution 3000 x 3000 pixel image map. So, you should check all your textures in Photoshop, and then reduce where needed.
