How do active ragdolls work in multiplayer games?

I’ve been playing with active ragdolls in a project of mine, but I’m curious how developers implement them in multiplayer games over WiFi. I assumed it would be impossible to do in a way that doesn’t have extreme input lag, since the server has to run the physics simulation - and doing local client predicted physics sim won’t really work for player interactions

But games like gang beasts seem to pull it off without noticeable input lag
