1800.0000, might be read incorrect by the game engine and cause bugs, if not altered to e.g.
In rare cases values with high numbers, e.g. Though floating-point variables may have up to 4 decimal places, it is recommended to cut them down to the last digit that is not 0. This doesn't count for string variables, which use nothing if their value is set to empty. Removing the value of a variable or the variable at all will not disable the according setting, instead the default value will be used by the game. Variables have to be put into the according section, to be taken into account by the game, with their value following a = in the same line. Only the first section with a specific label is taken into account, a second section with the same name would be completely ignored. Sections are defined by square brackets around the name, e.g. In the worst case all changes can be undone by deleting the Fallout.ini from its directory, so the game will create a new, default one with the next start.Ī file of this type can be edited with any text editor, though it is recommended to use a simple one – such as Windows' Notepad – to avoid unallowed symbols or unwished formatting. In addition it is wise to do changes step-by-step, so that unwanted effects can easily be reverted.Įditing the file can lead to game crashes, strange visual behavior, more errors or even a blue screen. It is strongly recommended to, before doing any changes to game files at all, make a backup copy of them. There are many guides and utilities spread across the web, regarding optimization, cleaning, and tweaking for an audio-visual appearance exceeding the game's ultra settings. Some possible variables aren't listed at all, but default values for them are hard-coded. For some variables it is unknown if the game really uses them. Some variables appear twice in the same section, in which case it's unclear which value is taken into account by the game, though it can be assumed, that this would be the first one. The sections and variables are in no specific order. Also some variables are contained in both configuration files, the Fallout.ini and the FalloutPrefs.ini, where the former determine the default values and the latter the values used by the game when playing it (with one definite and one possible exception: iPresentInterval and iRadialBlurLevel). The variables are organized in sections, with some appearing in more than one section. Some comments are contained, lines starting with.
The Fallout.ini, together with the FalloutPrefs.ini, is created when for the first time the launcher of the game is started.
