Satisfactory Dedicated Server: Network and CPU Requirements in 2026

Satisfactory is unusual among game servers: player count barely affects server load. What destroys performance is factory complexity — belt networks, drones, power grids, and train routes all run server-side. A small factory with 4 players needs less resources than a mega-factory solo.

Hardware Scaling by Factory Stage

| Factory Stage | RAM | CPU | |---|---|---| | Early game / exploration | 4 GB | 2 cores | | Mid-game factory (mk2–mk4 belts) | 8 GB | 4 cores | | Late game / nuclear + trains | 16 GB | 4 cores | | End-game megalith | 32 GB | 6 cores |

Plan your VPS size for where players will be in 3 months, not day 1.

Managing Save Files

Satisfactory saves are large and should be backed up regularly:

# Backup location
/home/satisfactory/.config/Epic/FactoryGame/Saved/SaveGames/server/

# Automated daily backup
0 3 * * * tar -czf /backups/satisFactory-$(date +%Y%m%d).tar.gz /home/satisfactory/.config/Epic/FactoryGame/Saved/

Performance Tuning

For large factories:

• Increase MaxNetworkBandwidth in Game.ini to prevent desync on complex factory visualisation
• Use Pause Game on disconnect to prevent the factory from running calculations when no players are online
• Monitor CPU single-thread performance — Satisfactory is largely single-threaded
