Why am I seeing a difference in performance from using the Editor vs Standalone build?

Have a few more readings on the problem. I tested another rig based off entirely different geo. Single instance of the mesh. Same result:

Then I started a fresh project, Blank no starter content. Imported original face rig above. Inserted single instance of the mesh. Profiled in editor, built executable, profiled in executable. Same result:

I’ve also applied the 4.1 framerate hotfix between the first post and this one.

Can you convert this to a bug report? Either the editor should reflect game performance or the game version needs to run as fast as the editor (I’d prefer the latter!).
