About this mod

Optimize inis to improve the Fallout 76 experience and improve performance.

This is my first mod, just some ini files. Fallout 76 is not optimized, and people like me online are improving their performance themselves. There are some optimized ini files here, mainly shadows, grass and effects are reduced or disabled. Take a look at the screenshot.

Please read:

I fixed the error by rewriting the ini file, there are less errors, but you have to do some work. After replacing the ini file, enter the game and change the settings, then exit and set the ini file to read-only.

Custom settings you can change:

How to change FOV set to 110: (CTRL + F & search for "FOV" in "Fallout76Custom.ini" and "Fallout76Prefs.ini")

Solution: Find iSize in both inis

Some problems you may encounter:

P: My menu won't load A: Delete your ini file and generate a new one by loading the game.

Update 1:

1.1 Fixed water turning black

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
