The limitations of traditional communication methods are a hot topic.

Lag in online matches is an unavoidable issue. With the delay-based systems that were once mainstream, players had to wait for inputs to reach each other, inevitably causing a disconnect in responsiveness. For fighting games where even a slight delay can dictate the outcome, maintaining a seamless experience has always been a major challenge.

The ingenuity of rewinding lag through technology is fascinating.

That is where Rollback Netcode comes in. Operating on the premise that lag exists, it proceeds by predicting inputs and then rewinds to ensure consistency—a truly brute-force yet brilliant approach. As we discuss this episode, it becomes clear why this technology is essential for the frame-perfect competition found in fighting games. Please check out the full episode to hear the rest.
