Load Level Instance ~ Create Multiple Transformed Instances of the Same Level, not in levels list!

Is it a convenience node or does it add functionality?
i.e. is there any benefit to this approach other than not needing to drag the levels to the Levels list?

Tried it with 4.13, but am getting a terrible performance using the node.
With “Get Streaming Level” + “Create Instance” my test setup runs at 120fps/8ms,
whereas when I replace it with the new “Load Level Instance” node, it dropps to 5fps/200ms.
Any ideas what could be causing this?

Edit: performance drop was due to me not providing the directory of the level, just the name (it still did find the level). Works fine now.
