My results are different!
In UE4 I could only place static mesh with 15 million vertex before before performace dropped to 30 ms. On UE5 with 50 million vertex its 16 ms, without any nanite. With 96 skinned mesh running around in a scene (crowd-humans, 40,000 vertex each, 4 animations) I get 17 ms.
I am yet try UE5 on production system and important projects as they don’t recommend it. Test system vulkan-linux 1050ti
