ELI5: How do online multiplayer games work so well despite so many differences in the systems behind each user (processing power, internet speed, display refresh rates)?

They avoid dealing with those issues at all tbh. What you send them isn’t what’s on your screen you send your inputs. Then your inputs get sent and the game reacts to them on your screen and the server. Lag is actually a result of this process being interrupted.

To restate for clarity everyone just puts inputs in and the server sends that info to everyone playing whose computer then interprets them.
