What is the performance of LOD and culling?

Unity Engine

I ran a silly test to see the benefit of pure DOTS and was surprised by how slow rendering was when we hit 100k entities.
so I wondered if the polycount was a bit much (30M) and saw LOD was eating up some so I turned off LODGroup and replaced 100 poly model by a tetrahedron impostor to a total of 3M poly and the speedup isn’t much. Batching seems to be eating up a lot.
So I was wondering if that’s indicative of progress to be made, expected performances for unrealistic scenario, and you guys using ECS for real how you use it. See what to expect.

thanks.

note: the entity debugger shows 500K entities because the prefab is made of one root and 4 children.

Have a look at this thread . There was a discussion and some experiments on that subject.
