And like I said... there is no direct correlation between the two, simply because it doesn't work that way anymore in modern operating systems.

Take Windows... your OS is pretty much always using "swap space", any idea why it's doing that? Memory management: no matter how much memory you have installed the OS will normally always try to "manage" it meaning so much that processes are monitored and if certain processes (or programs) have been deemed idle they're more than often "swapped out" aka their memory space gets temporarily stored on other storage media (usually disk) after which their part of the active memory gets freed up so that it can be used by something else, usually something more active.

And that same process of memory management also applies to VRam these days; though it works a little differently because virtual storage isn't used because of the speed requirements. Usually parts of VRam get swapped out to regular memory. 

Thing is... just because it's VRam doesn't imply that it gets used for everything that appears on your screen. Or in this case: everything that deals with video, like 3D objects.

Like I said in my first comment: it's still your OS managing things, NOT Daz Studio. While Daz Studio supports the Iray standard this doesn't imply that it keeps full control over everything, such as memory management.

And there isn't a direct correlation between these two. When I load a Genesis figure into Daz Studio's viewport then this doesn't imply that VRam (or a certain amount thereof) gets used right away. Of course that becomes a different story if I'm using viewport rendering like Filament or Iray but even then there is no 1:1 correlation between the object / product and its memory use. If anything your shaders and render settings will have much more impact on all that.

As such my above comment....
