Fast Save

Removes unnecessary information from save files, increasing the speed (up to 50% late game) of saving, loading, and auto-saving games. Includes an option to further speed up autosaves by moving some automatic save-related tasks into a background thread and replacing slow serialization routines with much faster delegates.

Make a backup of your save before using this mod.

• Removes old information in the Daily Report sections of the save, and allows autosaves to be conducted in the background during play.
  
• Options for this mod can be configured in the Mods screen.
  
• Existing save games must be loaded and saved again for this mod to take effect. Daily reports will only be checked and cleaned at nightfall.
  
• Safe mode does not affect achievements like Carnivore or Easy Living.
  
• Removing this mod will not break saves that it has affected.

Save Optimization - Controls how aggressively Fast Save prunes information

• Safe (default) - Does not visibly affect daily reports.
  
• Moderate - Preserves the 20 most recent daily reports while improving performance slightly. This mode may affect the Finely Tuned Machine achievement.
  
• Aggressive - Preserves only the 2 most recent daily reports to improve performance more. This mode may affect multiple achievements.

Background Save - Allows autosaves to be performed in the background

• Deselected - Autosaves will be performed in the foreground normally.
  
• Selected (default) - Parts of autosaves will be performed on a background thread, reducing the length of the associated gameplay freeze. Manual saves will be unaffected. No changes to the saved game format are made by this option.

Use Delegates - Experimental option! Reduces autosave time by up to 50%, but may crash the game. Use this option at your own risk.

Oxygen Not Included must be restarted for options changes to take effect.
