Explore network prediction techniques for creating responsive multiplayer games in this 40-minute conference talk from Unreal Fest Bali 2025. Discover how network prediction serves as the foundation for smooth, responsive input handling in multiplayer environments by predicting player actions locally on the client before reconciling them with the authoritative server. Learn the mechanics behind discrete states and timely rollbacks that enable immediate player feedback without waiting for server confirmation, particularly crucial for fast-paced movement and physics-based interactions. Master the implementation of Unreal Engine's Network Prediction Plugin (NPP), which handles the complex underlying systems, allowing developers to focus on game-specific logic rather than low-level networking code. Gain practical insights into optimizing multiplayer gameplay experiences through proven prediction algorithms that eliminate input lag while maintaining server authority and preventing cheating.
