That's just another kind of latency. Additional time has still passed from you (or the enemy player) doing an action, and you seeing the results of that action on your screen. By contrast, the server rolling back the game state is indistinguishable from the server always being 15ms behind and the clients running the simulation ahead of time (which they do anyway for fluency [1]). The "jumpiness" is called rubberbanding [2]. [1] https://www.gabrielgambetta.com/client-side-prediction-server-reconciliation.html https://www.gabrielgambetta.com/client-side-prediction-serve...
