Improve StarRupture Server Performance

This guide shows you how to optimize your StarRupture server performance – for fewer lags, more stable connections and a better gaming experience even with large bases and factories.

Optimize hardware

• CPU: StarRupture benefits greatly from high single-core performance. A modern processor with high clock speed is more important than many cores
• RAM: 10 GB minimum, 16 GB for larger bases and factories. Monitor RAM usage – if it exceeds 80%, upgrade
• Storage: Use NVMe SSD instead of HDD – autosaves and chunk loading are much faster

Optimize DSSettings.txt

You'll find this file in your server's main directory. Adjust the following entries:

{
  "SessionName": "MyServer",
  "SaveGameInterval": "600",
  "StartNewGame": "false",
  "LoadSavedGame": "true",
  "SaveGameName": "AutoSave0.sav"
}

• SaveGameInterval: In seconds. 600 = every 10 minutes. Increasing to 900 (15 minutes) or 1800 (30 minutes) reduces the number of interruptions
• StartNewGame / LoadSavedGame: After the first world creation ALWAYS set to false/true – otherwise the world will be overwritten on restart

Increase autosave interval

The autosave briefly freezes the server. The larger the base and the more players, the longer the freeze. Set the interval to 15–30 minutes to reduce the number of interruptions. With very large factories, a save can take several seconds.

Reduce view distance

View distance determines how many blocks are loaded around each player. A lower view distance significantly reduces CPU and RAM load. Reduce it in the server settings if players complain about lags.

Limit player foundations and factories

• Large foundation platforms are one of the biggest performance killers – similar to Satisfactory
• Build vertically rather than horizontally
• Distribute large factories across different areas of the map
• Keep conveyor belts and pipelines as short as possible

Reduce enemies and creatures

• Many enemies at once put heavy load on the server
• Reduce the spawn rate in server settings if possible
• Place turrets and traps so that enemies don't spawn in masses

Restart server regularly

• Daily restart prevents memory leaks – especially important in Early Access
• Use Windows Task Scheduler or cronjob for automatic restarts
• Always stop the server with stop or quit, don't close the window

Optimize network

• Run the server via LAN cable instead of WiFi
• Forward UDP port 7777 and query port 7778 correctly
• Avoid background downloads and streaming during operation

Quick checklist

1. Choose CPU with strong single-core performance, use NVMe SSD
2. Increase SaveGameInterval to 600–900
3. Set StartNewGame=false and LoadSavedGame=true
4. Reduce view distance if needed
5. Avoid large foundations, distribute factories
6. Restart server daily
