Setting the Benchmark for Multiplayer games.
Photon Fusion is the high-end state transfer netcode SDK made for Unity Professionals. Give players the best experience for any gameplay with multiple Network Topology choices.
Powerful Features required to build the Best Multiplayer Games:
Core feature of stable and accurate networking. Foundation for client side prediction and snapshot interpolation.
Give players an instant response to their own inputs without giving up server authority, even under high latency and network loss.
Full Physics Prediction
Get the best experience out of complex physics interactions between players and objects by using Full Physics Prediction.
Use automated or custom interpolation for smooth visual rendering even with bad internet conditions.
Built in Lag Compensated Hitboxes with easy to use API for Esport grade game mechanics.
Best in class implementations of replication algorithms for Delta Snapshots and Eventual Consistency with Interest Management.
Trusted by developers and studios all around the world
Fusion replication algorithms can be chosen based on game requirements.
Delta Snapshots are ideal for high-tick rate accurate state replication. Ideal for competitive games with lower object counts.
Eventual Consistency is ideal for games with high player or object count where bandwidth matters. It also adds interest management for further control.
An Evolutionary Leap in Multiplayer Engineering
Fusion is an evolution in multiplayer engineering by handling many more players and objects than ever before. Fusion’s bandwidth usage is 6x smaller than MLAPI or Mirror; it is optimized to consume less CPU on the server, allowing more flexibility for gameplay elements or lower server specs and deployment costs.
Flexible Network Topologies
Fusion supports different network topologies and replication algorithms while exposing a single consistent API. This allows developers to focus on what really matters most: writing their own game.
Dedicated server with public IP (headless Unity instance)
One Player is the „host“. All other Players connect to him.
Quality depends on host
Room has state authority and optional plugin (custom code).
Quantum: Each client runs a deterministic simulation.
