Satisfactory Server Performance Tuner

Generate an optimized Engine.ini for your Satisfactory dedicated server. Fill in your factory size and player count and copy the ready-to-use config below.

⚠️

Always edit Engine.ini while the server is shut down — a graceful shutdown overwrites the file.

Recommended Autosave Console Command

Run this in the Server Manager console after starting the server:

FG.AutosaveInterval 600

Interval in seconds. Default is 300s. Larger saves benefit from longer intervals to reduce lag spikes.

Key Settings Explained

NetServerMaxTickRate Always 30 — do NOT raise above 30. Higher values do not improve Satisfactory and cause instability.

InitialConnectTimeout Time before rejecting a new connection attempt. Increase for large saves that take longer to load.

MaxClientRate Bandwidth cap per client (bytes/sec). 104857600 = 100 MB/s — effectively uncapped for most connections.

mNumRotatingAutosaves How many rolling autosave slots to keep. More slots = more disk space but better recovery options.
