If there is a problem later the backup versions allow reverting to the original INI files. These two files should be backed up now (recommended) or at least prior to the step below that replace these files. The following instructions modify the two Fallout INIs: Fallout.ini and FalloutPrefs.ini! These are located in the %USERPROFILE%\(My )Documents\My games\Fallout3 folder. The entries in the last post in DoubleYou's forum thread work for all versions of Fallout 3 including the DVD, Steam and GOG versions. Any recommendations from INI tweak guides or internet forum posts should be ignored whenever they suggest adding entries that are not in the list compiled by DoubleYou. DoubleYou's post includes all the valid entries for the Fallout.ini and FalloutPrefs.ini files. Users who want more details on the entries in the Fallout.ini and FalloutPrefs.ini files should read at least the first three sections of the Skyrim INI Guide and DoubleYou's forum thread on valid Fallout 3 INI settings. This guide is intended to be comprehensive, and includes all INI tweaks recommended for Fallout 3. If fINIp has been used previously there is no need to uninstall anything.
The steps in this part of the guide can be applied at any time. This is an ancillary page for the Clear and Present DangerGuide for Fallout 3, created to reduce the length of that guide.
