Fallout New Vegas Tweak Guide
Fallout New Vegas is based on the same engine “Gamebryo” as Fallout 3 was, which provide a massive capability for tweaking. There are three methods excluding in-game settings to customize your game; Mods, .ini files and console commands. You can refer to the Tweak Guide below to play around with your game to either enhance its beauty or improve performance.
Fallout New Vegas Configuration Tweak Guide
The two main .ini files which concern us are “Fallout_default.ini/Fallout.ini” and FalloutPrefs.ini which can be found here
\Program Files\Steam\userdata\(your UID, probably the only folder in there) \22380 (the game ID assigned by Steam to Fallout NV) \remote\falloutprefs.ini).
Now all the changes you make in Fallout.ini, you will have to do the same for “Fallout_default.ini” which can be found here
\Program Files\(x86)\Steam\steamapps\common\FNVegas
as it overwrites all the changes to “Fallout.ini” every time the game runs. So it is highly recommended that you make a backup of “Fallout_default.ini” config file.
There are many variables which do not affect the performance much and there are some which are altered from the in-game settings, hence we are excluding all those non useful variable, and focusing our attentions on only useful ones.
File name you need to edit for the tweak is also written against each variable, so you just have to open that configuration file in any text editor and find the specified variable (CTRL + F) and change values to recommended ones.
Fallout New Vegas Tweak Guide
iPresentInterval=0 – Disables/Enables Vertical Synchronization (VSync). Found in (Fallout_default.ini)
fForegroundMouseMult=4.0 – Mouse acceleration (increasing value will increase mouse speed and vice verse). (Fallout_default.ini)

fForegroundMouseBase=0 – (Fallout_default.ini)
fForegroundMouseMult=0 – (Fallout_default.ini)
bDisableAllGore=1 – Disables/Enables Gore (blood decals, dismemberment , etc) from game. If set to 1 it will disable Gore. (Fallout_default.ini)
bAllowScreenShot=1 – If value =1, it will allow you to take screenshot in-game with PRINT SCREEN key (screens will be saved as .bmp in \Steam\steamapps\common\Fallout New Vegas , or you can also use any software like Fraps. (Fallout_default.ini)

iConsoleTextYPos=900 – Determines console command’s text Vertical Position
iConsoleTextXPos=20 – Determines console command’s text Horizontal Position
iConsoleVisibleLines=05 – Determines Maximum Number of console command lines displayed on screen
rDebugTextColor=255,251,233 – Determines color of the console text font, use this RGB Calculator for color code reference (Fallout_default.ini)

I can’t tell you how thrilled i am to have found this, i wish i had used this guide on fallout 3. Previously, my game was stressfully jumpy and laggy, even though my computer should have run fallout easily, after this, jumpiness is minimum, i can finally do smooth sweeping motions with the reticle, and i think doing an optimizing defrag should iron out any of the kinks left over.
p.s. i only copied the options from the performance section, if you read this, should i copy all the other options as well?
Thanks again ☺

thanks for this guide, i have a crappy lappy so needed guides like this to lower the graphical quality of the game
Great guide. Just wanted to make one point.
iMinGrassSize is just the exact opposite.
RAISING the value increases FPS and lowers
the density of the grass.
LOWERING the value increases density and
delivers a blow to FPS.
Well done guide, though.

Sorry to ask such noob question, as im not a good at tweaking
I can’t find the UInterior/Exterior CellBuffer in Fallout_default.ini
Should i create one and put it in, and which sec to put it in
Jay,
The easiest way to locate any of those is to go up to your header in
Notepad and push “Edit”, then select “Find”. A new small window will pop up
and just enter the line you are looking for, then push “Find Next”. I usually
just enter the first part, such as, uInterior and search for that.
* FYI- It should be line 50 and 51 when opened up in Notepad.
@Jay: its near the top of the list and it has SPACES lol thats why you couldn’t find it, its UInterior Cell Buffer / UExterior Cell Buffer. at least on MINE it has spaces.. hope that helps lol, that is, if you STILL haven’t found it yet
@Jay look for:
uInterior Cell Buffer
uExterior Cell Buffer
Yes there are spaces there. That’s why you cannot find it.
where do i find the .uni files, i looked through the steam folders and apparently i don’t have the folder for new vegas even though i already downloaded and played it, any ideas?
I always wanted to know how to pick more than 2 traits, and so i kept playing around tili figured out the console command — “showtraitmenu” — type this in (minus quotation marks..duh) and you can pick 2 new picks each time or just one, or none; have fun!!!
Note : there’s a small typo
\PreloadSizeLimit……..users with 1GB RAM try 5242880………\
There’s a missing zero on the suggested 1GB setting – it should be 52428800 not 5242880. If you leave off that zero game will probably freeze up pretty quickly
Can’t seem to find the bDisableAllGore=1 setting in the fallout_default.ini, are you sure it is actually in there? I would like to disable some of the gore because I play in front of my kids.
this line is there to start with, it sometimes work temporarily but the game quickly removes the line from .ini file and the gore returns. First and foremost, make sure you search the line in Steam/steamapps/common/fallout new vegas/Fallout_default.ini and if that doesn’t work – try this Gore Tweak Mode.
If you increase some settings, like uGridsToLoad, your savegames may not work if you lower the setting again. The game will crash on loading.
I’ve been trying to play this on my HP Mini forever. I know it sound absurd, but I love the Fallout series and I really wanted to play this one. This increased FPS tenfold!
Thank you so much. Amazing work.
there’s a tool which makes tweaking easier, it lists all the important things and you just change the ones you like and it automatically saves everything for you.
