This document discusses advanced techniques to improve network communication and engine performance.

Data Packing and Compression

• Use smaller data types for network messages.
• Implement efficient serialization (e.g., RLE or LZ4) to reduce bandwidth.

UDP Reliability

• Implement an acknowledgement (ACK) mechanism for critical messages.
• Use packet duplication and reordering techniques as needed.

Synchronization and Prediction

• Implement client-side prediction to compensate for latency.
• Use reconciliation to correct state differences between client and server.
• Monitor latency and display metrics (FPS, lag, etc.) for debugging.

Profiling and Debug Tools

• Integrate an in-game developer console for on-the-fly commands.
• Display in-game statistics (CPU usage, memory, entity count, etc.).
