"Unfortunately a lot of the graphics-related issues are indirectly caused by the game’s use of DOTS"
"The cause for unnecessary geometry is both the lack of simplified LOD variants for many of the game’s meshes, as well as the simplistic and seemingly untuned culling implementation. And the reason why the game has its own culling implementation instead of using Unity’s built in solution (which should at least in theory be much more advanced) is 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"
