The idea is that it predicts the inputs from other players before they input them, simulating the next frame without delay based on what it thinks will happen next.
Once the opponent’s input does arrive, anything not matching what was predicted will be roll back to the previous state of game and replays all players’ revised inputs back until the current frame. In layman’s terms, this is the future of online netcode for fighting games and should make lag a thing of the past.
