In addition it is wise to do changes step-by-step, so that unwanted effects can easily be reverted. 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. The variables are organized in sections, with some appearing in more than one section.Īlso some variables are contained in both configuration files, the Fallout. It normally remains unchanged, though the Fallout: New Vegas version is overwritten with default values each time the game is started via Steam. It is then saved in the user's My Game directory. It contains values about audio and graphical options, background processes, implementation of the Havok Physics engine, and many more.
