TPS drops when adding an entity to the scene

[AtAshTag]

Ok so this is with the Sleep(0.0)

So when the thing is added with the sleep it still takes a hit (Only comps now) no meshes ect when i had some meshes it was so worse.

Video:

Main Farm Plot With Sleep

Then without Sleep(0.0)

Main Farm Plot No Sleep(0.0)

Again this is just a prefab with comps thats it
