Hi!
I'm going out of RAM scattering a decals over two surfaces: the first one is asphalt (Chaos Cosmos Material) and the second one is a grass plane (with scattered grass).
The decals material is a texture of fallen leaves that has Albedo, Bump, roughness and Displacement texture.
I've set 1000 instances, but I run out of RAM quickly during displacement computation! Same if I scatter the decals over asphalt and not over the grass plane. The only way to render is to avoid to place the decals over the (scatterd) grass.
