Instances, what the point?

I was curious about how instancing static meshes work.

I am guessing we’re talking about instanced static meshes here; For some reason this does not seem to work in your setup, otherwise your performance would be equal.
Bottomline: I’d check your setup and figure out why performance is not equal

The performance isn’t equal because Instanced Static Meshes are different from the editor-default instances of a static mesh.
To make use of Instanced Static Meshes, you’d have to make an actor blueprint and add the meshes as Instanced Static Mesh Actors and add the instances manually there.
So that’s why the framerate is poopy.
