Wow

HISM gives about same results + some sunny invalid spots that pop in and out:

I start to get the feeling that instancing is not supported at all or experimental, for Lumen. When I spawn same amount without instancing, fps goes bad, but the worst is the time that it takes to spawn.

I tried it, and then killed the editor

I can’t recall which way round it is, but the lumen scene is different for ISM vs HISM.

Thank you for your help. Would be great if somebody from UE team jumped in shade light on this situation. But I guess that a silly expectation.

That’s not gonna happen
