Tree Performance; DOTS vs HDRP Terrain vs Nature Renderer

Unity Engine

Hello Community,

at this point I would have wanted to provided the solution by myself, but as I am currently busy with my project, I need a short answer for this, so I can decide if integrating it is worth the hassle or not.

I would want to know if creating Trees (40K), Bushes (40K) and Grass (multiple million quads) over a 2048x2048 big Terrain using DOTS with Jobs and Burst would be more performant than using the default Terrain techniques and even more performant than the Nature Renderer in Unity 2022 HDRP 14? Moreover, can I use MeshColliders for the DOTS tree’s and would they interact with GameObject colliders?

Has anyone tested that already and can share the results?
That would be awesome! Thank you.

I am sorry for not having it done right in the first place, but can one forum moderator migrate this question to the DOTS area, please.
