Multiplayer Architecture & Framework Selection

Project: Shatterpoint (Lead Role)

Multiplayer architecture diagram with server and clients

Problem

The original fully deterministic approach with Photon Quantum caused frequent desyncs, complex reconnection logic and high debugging cost.

Analysis & Decision (as Lead)

After deep analysis and team discussion I recommended switching to an authoritative server model with Photon Fusion (client prediction + state correction). I used AI tools extensively to prototype both architectures quickly.

Outcome

Much more stable gameplay, simpler reconnection, drastically reduced desync bugs and faster iteration for the entire team.

Key Takeaway

Framework choice must match actual gameplay scale and production reality. For small, fast-paced sessions simplicity and debuggability beat theoretical determinism.
