Here are some stats on a simple example without texture:
Plain Polygrid 8096 spans about 3.2 GB total (pure geometry)
Plain Polygrid 2 spans but 8096 Microdisplacement Spans 1.2 GB total (micro displace geometry)

I tried it again this time like you did with only a polygrid without texture. With the empty scene Clarisse needs about 354MB. When I create a polygrid and raise the span count to 8000 it goes up to around 6.8 GB

what is the real difference between subdividing or adding geometry span ?

i think that everybody want a good tutorial who explain how to set up displacement base on real texture not fractal noise.

we want to see how far clarisse can go with fine displacement details .

i am trying to figure out what is the best methode to use for displacement
adding displacement adaptative space count
adding geometry span
geometry deformer by displacement
or geometry ray subdivision
