Issues fixed[edit]

Resolution change causes the game to crash[edit]

Changing the resolution of the game from the in-game settings menu cause the game to crash.
Manually edit the config[5]
  1. Go to the configuration file(s) location.
  2. Open Settings.json using any text editor.
  3. Adjust lines 2 and 3 to your desired resolution
    • "DisplayFullscreenWidth": 1280
    • "DisplayFullscreenHeight": 768
  4. The game will now correctly run at your desired resolution without crashing..


Changing your resolution to anything higher than 1080p causes sub menu items to display in the wrong position on screen, functionality is still perfect however.
The provided samples are the default settings for the settings file.


Stuttering may be reduced by freeing video RAM[citation needed]

This can be done in-game by:

  • Reducing Texture Quality
  • Reducing Resolution
  • Reducing Anti-Aliasing

This can also be done in Windows by:

  • Disconnecting Secondary Monitors
  • Closing VRAM heavy applications, e.g. Web Browsers
  • Change to windows basic theme (Windows 7 only)

Lock-on missiles not working[edit]

If using mouse and keyboard, lock-on missiles in vehicles might not work. Bug unpatched since launch.
Disable 'precision aim' Gear MOD and restart the game.[6]
  1. Go to the Gear MOD menu for weapons.
  2. Disable the Precision Aim MOD.
  3. Restart the game.
  4. The game will hopefully let missiles lock on.
Use an XInput controller.[7]
  1. Plug in or connect an XInput controller
  2. Start Steam Big Picture
  3. Launch Just Cause 3
  4. The game will hopefully let missiles lock on.
