The PC version of Fallout 4 has a bevy of tweaks and thankfully many of them related to the engine are pretty well know from the Skyrim days. So, here are the best of the best and the rest of the rest Fallout 4 interface tweaks.
There are three key files you need to find to make these tweaks. These are:
Fallout4Prefs.ini (found in your Steam directory)
It is located in your Steam directory in the Fallout 4 directory inside the Fallout 4 root directory and is called Fallout4Prefs.ini. The path most likely looks like C:Program Files (x86)SteamsteamappscommonFallout 4Fallout 4Fallout4Prefs.ini
Fallout4.ini (found in your My Games directory)
This is located in your My Games folder and is called Fallout4.ini. The path most likely looks like C:UsersUserNameDocumentsMy GamesFallout4.ini
Fallout4Prefs.ini (found in your My Games directory, different file from the Fallout4Prefs.ini in your Steam directory)
This is located in your My Games folder and is called Fallout4Prefs.ini. The path most likely looks like C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
With that out of the way, onto the Fallout 4 tweaks.
Field of view (FOV) tweak
Field of view is the first tweak to consider. Just add the following lines to your [Display] section of your ini file. I like 90, but some people use 110. If you don’t have an opinion then 90 is my recommendation.
Open C:UsersUserNameDocumentsMy GamesFallout4.ini
Add, in the [Display] section:
[Display]
fDefaultWorldFOV=90
fDefault1stPersonFOV=90
Open C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
Add, in the [Display] section:
[Display]
fDefaultWorldFOV=90
fDefault1stPersonFOV=90
Open C:Program Files (x86)SteamsteamappscommonFallout 4Fallout 4Fallout4Prefs.ini
Add, in the [Display] section:
[Display]
fDefaultWorldFOV=90
fDefault1stPersonFOV=90
You should now have a more natural field of view on your next play session. There are field of view options in the [Interface] section. Don’t worry about those.
Now, tweak the Pipboy and your gun!
1. Open the Console with Tilde (~)
2. Type: ‘fov ##’ (smaller is larger)
3. Type ‘refreshini’
4. Type Tilde again
5. Save and Reload and G2G
Tweak to remove mouse acceleration
Open C:UsersUserNameDocumentsMy GamesFallout4.ini
Add, in the [Controls] section:
bMouseAcceleration=0
Open C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
Add, in the [Display] section:
bForceIgnoreSmoothness=1
Open C:Program Files (x86)SteamsteamappscommonFallout 4Fallout 4Fallout4Prefs.ini
Add, in the [Display] section
bForceIgnoreSmoothness=1
Frame rate unlock tweak
Frame rates above 60 have been known to do bad things in Skyrim and all indications are that this is true in Fallout 4 also.
Open C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
Search for: iPresentInterval=1
Change to: iPresentInterval=0
Skip the Fallout 4 Loading Intro
If you are like me you don’t leave the game very often, but if you want to get in game just a little faster try out this tweak.
Go to: C:Program Files (x86)SteamsteamappscommonFallout 4DataVideo
Delete the file GameIntro_V3_B.bk2
You can also skip the intro by making this adjustment:
Open C:UsersUserNameDocumentsMy GamesFallout4.ini
Add, in the [General] section:
SIntroSequence=1
Make Vertical and Horizontal Mouse Travel The Same
Open C:UsersUserNameDocumentsMy GamesFallout4.ini
Find: fMouseHeadingYScale=.021
Change: fMouseHeadingYScale=.03738
This will work on 16:9 monitors, other resolutions and ratios may need tweaks.
Fix Invisible Lockpicks
Apparently when unlocking framerates and without VSync your lockpicks can seem to disappear or turn invisible. To fix this requires a few small changes.
Open C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
Under the [Display] section change:
iSize W=NUMBER1
iSize H=NUMBER2
to:
iSize W=NUMBER1-1
iSize H=NUMBER2-1
If NUMBER1 was 1920 then you would change it to 1919. The same goes for NUMBER2.
Disable Gamepad
If you know you don’t want to user your gamepad, but you want to keep it plugged in then Fallout 4 will freak out and put you in controller mode every time. To keep this from happening, disable the controller like this:
Open C:UsersUserNameDocumentsMy GamesFallout4Prefs.ini
Change:
bGamepadEnable=1
to:
bGamepadEnable=0
