Meccha Chameleon Host PC Optimization — P2P Lobby Guide

Golden rules

1. Ethernet mandatory for host
2. Close uploads (OneDrive, torrents, streams)
3. Cap lobby at 8–10 players (dev recommends 2–10)
4. Avoid hosting above 14 — desync and rubber-banding
5. Pick host with best upload, not best PC graphics

Router

• Enable UPnP or port forward
• QoS prioritize gaming PC if router supports it

Hardware

UE5 load spikes when many players paint — close background apps.
