How to verify 4.22 auto static mesh batching?

Hi! Inside 4.22 and 4.23, when I spawn lots of static meshes blueprints, FPS drops considerably. Before I had Instance Statc Mesh Component Setup and never had this issue.

How to verity, that 4.22 auto instancing actually works?

So far I tried:

Cmd: r.MeshDrawCommands.DynamicInstancing 0
Cmd: r.MeshDrawCommands.DynamicInstancing 1

but FPS stayed the same, no effect
