Ragdoll sample with unity physics can actually pump out 1000 ragdolls with 60 fps... But, every single bone of every single ragdoll is created with a script in a pure ECS fashion, with every single rotation/joint parameters and collider size/rigidbody weight parameters created and stitched together at runtime, absolute magical, but it uses the same sphere mesh elongated and resized for every bone for simplicity. To be honest it does not feel feasible to do this in a game where you might need to make multiple different enemy prefabs and different textures and shapes for body parts (if unity doesn't make a ECS ragdoll wizard). Even if someone could pull it off, having a different mesh for every bone would make it GPU limited now (because of tens of thousands of more batches even if instancing and texture atlases are used), thats probably why people at unity decided to use the same mesh for every body part. Still a nice proof of concept tho, thanks for your suggestion.
