Fallout 4 Custom INI Download

Fallout 4 is a popular post-apocalyptic role-playing game developed by Bethesda Game Studios and published by Bethesda Softworks. The game allows players to explore a vast open world, customize their characters, craft weapons and armor, build settlements, and engage in various quests and combat scenarios. However, some players may want to tweak the game settings or enable modding to enhance their gaming experience. For this purpose, they need to edit or create a file called Fallout4Custom.ini, which is a configuration file that contains various commands and parameters that affect the game's behavior.


In this article, we will explain what Fallout4Custom.ini is, how to create or edit it, and where to download some useful presets that can improve the game's performance, graphics, or gameplay.

What is Fallout4Custom.ini?

Fallout4Custom.ini is a text file that can be found in the Documents\My Games\Fallout4 folder of your computer. This file is used to store custom settings that override the default ones in Fallout4.ini and Fallout4Prefs.ini, which are the main configuration files for the game. Fallout4Custom.ini is usually blank or non-existent when you first install the game, but it can be created or edited manually or by using third-party tools or mods.

The advantage of using Fallout4Custom.ini is that it allows you to change the game settings without affecting the original files, which may be overwritten by updates or patches. It also makes it easier to enable modding, which requires adding two lines to the file: bInvalidateOlderFiles=1 and sResourceDataDirsFinal=.

How to create or edit Fallout4Custom.ini?

There are two ways to create or edit Fallout4Custom.ini: manually or using a tool.

  • Manually: You can use any text editor, such as Notepad, to create or edit Fallout4Custom.ini. You just need to save the file as Fallout4Custom.ini in the Documents\My Games\Fallout4 folder. You can then add any commands or parameters that you want to change in the file, following the same format and syntax as in Fallout4.ini and Fallout4Prefs.ini. You can find a list of available commands and their descriptions [here]. You can also copy and paste some commands from other sources, such as online guides or forums.

  • Using a tool: You can also use a third-party tool, such as [Fallout 4 Configuration Tool] or [BethINI], to create or edit Fallout4Custom.ini. These tools are designed to make it easier and safer to change the game settings, as they provide a graphical user interface and various options and presets. They also automatically backup your original files and create Fallout4Custom.ini for you. You just need to download and run the tool, select your desired settings, and apply them.

Where to download Fallout4Custom.ini presets?

If you don't want to create or edit Fallout4Custom.ini yourself, you can also download some presets that have been made by other users or modders. These presets are usually designed to improve the game's performance, graphics, or gameplay by changing some settings that are not available in the game's options menu. For example, some presets may disable mouse acceleration, unlock framerate, adjust sun shadow values, disable pipboy effects, etc.

You can find some examples of Fallout4Custom.ini presets on [Nexus Mods], which is a website that hosts thousands of mods and files for various games. Some of the most popular and recommended presets are:

  • [Essential Custom.ini]: This preset contains what the author believes to be the most useful or essential commands tweaks for Fallout 4. It enables modding, disables mouse acceleration, unlocks framerate, skips intro, enables multi-threaded commands for improved performance, disables fake lighting for the player and NPCs alike, adjusts pipboy and UI color and size, disables tutorial messages, and adds adjustable commands for water effects, grass, precipitation, screen blood effects, gore, radial blur, NPCs use ammo, auto saving, and save backups.

  • [Fallout 4 - Texture Optimization Project]: This preset is part of a mod that aims to optimize the textures of Fallout 4 to improve performance and reduce stuttering. It also includes a custom ini file that disables some settings that are not needed or cause issues, such as god rays, lens flare, motion blur, depth of field, ambient occlusion, etc.

  • [Fallout 4 - Ultra Low Graphics]: This preset is for players who have very low-end PCs and want to run Fallout 4 at the lowest possible settings. It reduces the resolution, draw distance, shadow quality, lighting quality, texture quality, and other settings to the minimum. It also disables some effects and features that are not essential, such as water reflections, grass, decals, fog, etc.

To use these presets, you just need to download the file and extract it to the Documents\My Games\Fallout4 folder, replacing the existing Fallout4Custom.ini file. You can also backup your original file before doing so, in case you want to revert the changes.


Fallout4Custom.ini is a configuration file that can be used to change the game settings or enable modding for Fallout 4. You can create or edit it manually or using a tool, or you can download some presets that have been made by other users or modders. By using Fallout4Custom.ini, you can enhance your gaming experience by improving the game's performance, graphics, or gameplay.
