I mean it’s what I do professionally as well. I haven’t been doing it nearly 16 years, but have been at it near 10. What I was explaining with cars and vehicles is extrapolation on servers can be accurately done because of dead reckoning. The video explains why determinism in you physics isn’t necessary, but that your packets and inputs need to be. That’s the purpose of jitter buffers and input buffers on the server. Because the server has your last input, and you’re in a car, it can simulate the car in a predictable way.
