Factorio has a number of settings in different places, this page covers the ones accessible through the Main menu and Game (pause) menu. These settings are also saved to and can be changed from the "config.ini" file in the Factorio user data directory. The #See also section covers other places that allow configuring the game.

Mod settings

Main article: Tutorial:Mod settings

Settings added by mods are placed here. There are 3 sections: Startup, Map and Per player. Each section contains a list of settings, grouped per mod that added them.

Startup settings require the game to be restarted. This means closing and opening the game, not resetting progress in a save file. Map settings can be changed while the game is running. Per player settings can be changed while the game is running and allow each player to have different values in the settings.

Hidden settings

Factorio supports a number of hidden configuration options that are not normally shown in the GUI. They can be accessed by holding CTRL + ALT when clicking the "Settings" button in the pause menu, which will cause a new button labeled "The rest" to appear.

These settings may be experimental and may not be validated for safety, so change them at your own risk.

Notable hidden settings

Name	Default	Description
Other settings
autosave-slots	3	How many autosaves to keep on a rolling basis
cache-prototype-data	false	When enabled, significantly speeds up the "Building prototypes..." step when starting the game at the cost of increased storage space, if prototypes haven't changed since last startup. The cache needs to be built first, so the loading time will increase when rebuilding it, such as when the setting is enabled for the first time.
non-blocking-saving	false	Only works on Mac and Linux. When set to true, saves do not cause the game to pause. [1]
technology-gui-pauses-game	true	Whether the game is paused in singleplayer while the technology tree is open.
autosave-when-platform-travels-to-new-location	true	Whether the game autosaves when a space platform travels to a new location.
circuit-network-selection-always-enabled	false	If true, circuit network UI elements are always modifiable, even if their value is irrelevant due to other settings or missing wire connection.
Interface settings
quick-bar-width	10	Adjust the number of horizontal slots in each row of the quickbar. Valid range of 10 - 100 [2]
main-menu-simulation-selector	false	Shows a dropdown on the main menu allowing to select a simulation to play in the background. Can be useful for modders when creating custom simulations.
Graphics settings
cache-sprite-atlas	false	When enabled, significantly speeds up the "Loading sprites..." step when starting the game at the cost of increased storage space, if sprites haven't changed since last startup. The cache needs to be built first, so the loading time will increase when rebuilding it, such as when the setting is enabled for the first time.
