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
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.
| Name | Default | Description |
|---|---|---|
| autosave-slots | 3 | How many autosaves to keep on a rolling basis |
| non-blocking-saving | false | Only works on Mac and Linux. When set to true, saves do not cause to game to pause. [1] |
| technology-gui-pauses-game | true | By setting to false, the game will no longer pause in single player when opening the technology tree. |
| 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. |
| 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. |
| 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. |
