It is not recommended to use these as your INI Files! Well, actually, on second thought, I totally recommend everyone replace their FalloutPrefs.ini with the one given here and selecting your Fallout Launcher preset again, as the default INI generation mechanism makes a royal mess out of the FalloutPrefs.ini file.Įxtra tip: Fallout 3 allows you to make a Custom.ini that works just like the SkyrimCustom.ini if you care to do so. I have also added relavent comments left by Bethesda from the Fallout_default.ini file and some of my own. From this I have created a the following, which is a comprehensive list of all valid settings for Fallout 3(any settings not listed here are invalid and not recognized by the game) along with their default values, with floating point values estimated to four decimal places. In my research with Skyrim INI settings, I figured it would be fun to apply what I've learned to Fallout 3.
