Quote - Poser 7 will use up to 4GB of memory on Windows 64-bit - if and only if (for some logic) that memory is available.  If you have 4GB, it ain't gonna use 4GB because a portion of that is already in use for the OS, drivers, services, other software.  On the other hand, if you have more - say, 8GB like me ;) - it should be capable of using the full amount.

My thoughts - a 64-bit OS with 4GB or less is a waste.  What does 64-bit addressing give you?  A way to have more than 4GB and use it.  That's it (besides side-effect advantages).

Don't knock it until you've tried it. ;)

well I have 64 bits XP last sp and two Video cards latest OpenGL, etc..running SLI right now and 8 Gb ram uyes EIGHT the stupid application takes max 3, something  Gb and as I said..depending on it's mood
just for fun, and obsevation I just render A3 with a texture naked no hair. Took eternally (well for simplicity of the rending I mean)
bull total about when you make animation..I had made several dynamic dresses in V3 and V4 and max 130 frames - does not speeds up. Does not uses all 4 Gb  as it's supposed and not takes advntage of my 4 CPU...total mistake from my part to buy such expensive system...well waters under the bridge anyway.

BTW I had also a 75 GB WesternDigital Raptor HDD. which gave me no more speed to Poser. so decide to use for soemthing else and give Poser a 500GB single external HD WD as well but 7200 rpm - whic I made tests to see if was any difference w/ system today and the external drive and Sata internal...no..none..makes the rendering of that 'benchmark' you know the one done by many of us...in 4 min. as in one HD or the other! Proff of males no difference...
As they say you can never say if this or that will work best in you rig unless you use it and test it.
