In my research with Skyrim INI settings, I figured it would be fun to apply what I've learned to Fallout New Vegas. From this I have created a the following, which is a comprehensive list of all valid settings for Fallout New Vegas (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. I have also added relavent comments left by Bethesda from the Fallout_default.ini file and some of my own. 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.
 
Extra: Unfortunately in Fallout New Vegas there is no equivalent to SkyrimCustom.ini in Skyrim, so any INI settings that you do not want to get overwritten by the Fallout Launcher or Steam should be loaded as a plugin INI or Mod Organizer INI tweak. No matter what, even if you set Fallout.ini to Read-only mode, Fallout Launcher will take control of Fallout.ini and force most if not all of its "default" settings from the Fallout_default.ini file.
 
Please note that these values and settings are not the same as the Fallout_default.ini in the Fallout New Vegas game directory, which is copied as your default Fallout.ini file at startup. These are the default settings that are hardcoded into the game itself if the setting is not specified to be some other value. In the case of the FalloutPrefs.ini, most of the defaults are determined by the values assigned when pressing the Defaults button in the in-game settings. The rest were gathered from the saveini command with a blank INI with three exceptions.
 
With three exceptions. Those three exceptions are the following, which are required to exist in the Fallout.ini for Fallout New Vegas not to CTD at startup. It is assumed that the default settings for these three settings are erroneous, and therefore the values from Fallout_default.ini were used. These three settings are:

[Archive]
SArchiveList=Fallout - Textures.bsa, Fallout - Meshes.bsa, Fallout - Voices.bsa, Fallout - Sound.bsa, Fallout - MenuVoices.bsa, Fallout - Misc.bsa

[Fonts]
SFontFile_2=Textures\Fonts\Monofonto_Large.fnt
SFontFile_7=Textures\Fonts\Baked-in_Monofonto_Large.fnt

Without these settings, Fallout New Vegas will CTD at startup.
 
It should also be noted that four settings also had to be added to the FalloutPrefs.ini in order to satisfy the Fallout Launcher that it needed to detect game settings, or are only used by the Fallout Launcher and therefore reproduced here, as they do not affect the main Fallout New Vegas game in any way:

[Display]
sD3DDevice="AMD Radeon HD 8650G"
;This is the name of my video card, which would be the name of your video card. This is the only setting required for the Fallout Launcher not to run its detection.

[Launcher]
bEnableFileSelection=0
bShowAllResolutions=0
uLastAspectRatio=1
;These three setting are only used by the Fallout Launcher, and these are the defaults. They have been changed in the FalloutPrefs.ini below to their most desirable values.

Now here are the default INIs:

Okay, so seeing how messed up Fallout New Vegas INIs are, I decided to clean them up a bit. I have gone through the Fallout_default.ini, which is applied to both Fallout.ini and erroneously to FalloutPrefs.ini at Fallout Launcher startup (most annoying) and removed all the erroneous settings and all lines that are not different from the default. The result is given below:

 

Fallout_default.ini

 

 

  Reveal hidden contents

 

 

 

As you can see, I've added comments throughout to tell of the changes from the default values. Most of these changes are assumed to be fixes (a large number of them are at least) and are recommended to be in everyone's Fallout.ini.

 

 

What I recommend

 

Edit your Fallout_default.ini file in the Fallout New Vegas directory to have only the following within:

 

 

  Reveal hidden contents

 

 

 

This will cause the Fallout Launcher only to apply these necessary changes to the Fallout.ini at startup. Unfortunately, this doesn't stop it from erroneously copying these to FalloutPrefs.ini initially, however, copying the default FalloutPrefs.ini below and tweaking it to My Games\FalloutNV and then applying your preset will allow you to have only the necessary lines.

I was so confused by this initially (a while ago when I first started modding FNV) that what I did to overcome this was just copy every unique line from fallout.ini and falloutprefs.ini both and include all of them in both files. Then anytime I changed a setting in one of them, I also did it in the other. Then I let the game decide on it's own from which ini file it wanted to read whichever given setting. That's what solved my problem. :)
