Displacement high memory usage.

Theme3D

I trying to use subdivision to get displacement to work, or even HD details, but I only have 16gb ram.

Trying to go with subdiv beyond 2 makes my computer hangs, all the memory is rapidly consumed by DazStudio, and the computer gets super slow and HD swapping.

Is there any techinique to get displacement or hd subdivion that don't consume too much ram, or do I need 32gb of ram to work with subd beyond 2?

Have you tried converting the displacement map into a normal map (you can do it here: https://cpetry.github.io/NormalMap-Online/ ) and then using that instead? It might be good enough to give the effect you want, and doesn't need any subdivision at all.

SubD 2 shouldn't cause an issue with 16GB RAM, unless the initial polygon count of the model is high.
