I have a large number of enemies/projectiles, what is the best solution to synchronize their position and rotation? Not sure Ghost Authoring Component is suitable for large crowds

check yourself. i think ghost is enough. the main point is network bandwidth.
btw dont sync all ghost to clients

Hey mrgolemm, a few links: https://discussions.unity.com/t/941564 & https://docs.unity3d.com/Packages/com.unity.netcode@1.2/manual/optimizations.html

Using ghosts can work, but it depends a lot on your use-case. Is the crowd static? Or mostly static? If so, you can probably use a deterministic RNG seed (for example), then you only need to create ghosts for any crowd entities that move (or get interacted with). Are we talking hundreds? Or low thousands? Or many thousands?
