"And the reason why the game has its own culling implementation instead of using Unity’s built in solution because Colossal Order had to implement quite a lot of the graphics side themselves because Unity’s integration between DOTS and HDRP is still very much a work in progress and arguably unsuitable for most actual games."

This sadly tracks with my own experiences with Unity's tooling, where DOTS did ship but its implementation rots on the vine like every other tool they acquired. The company is woefully mismanaged, its been mismanaged, and given the very public pricing incident from a few weeks back, they aren't focusing on improvements to the engine, but on any way to scrap money from its users.

Bevy's ECS implementation is really good, and I want to see it succeed here, in addition to Godex.
