Fallout 4 Tweaks

Just a few hours later after the release of Fallout 4, the community has already found some tweaks and most of them are from the steam user Gabi. He also published a guide to experience improved performance of the game on your PC.

Unlocking Frame Rate

Bethesda previously claimed that the Fallout 4 will give more than 60 FPS on PC but it didn't turn out to be true as the game's frame rate is locked by default and in order to unlock it you'll have to open the file Fallout4Pref.ini located at C:\Users\[name]\Documents\My Games\Fallout4\ and change iPresentInterval=1 to iPresentInterval=0 and perform the same for Fallout4.ini and make sure both the files are read only or they will be reset when the game is launched.

Changing FOV (Field of View)

The default field of view might be having some restrictions for some players. To change the FOV, you need to modify the following strings in Fallout4.ini in the following way:

fDefaultWorldFOV=90
fDefault1stPersonFOV=90

and

fSafeZoneYWid=27.428571428571428571428571428571
fSafeZoneYWide16x10=27.428571428571428571428571428571

21:9 Support

If you have 21:9 display then you need to perform the following to support this aspect ratio.

If you prefer full screen, perform the following:

bTopMostWindow=0

bMaximizeWindow=0

bBorderless=0

bFull Screen=1

iSize H=XXXX

iSize W=YYYY

and if you prefer windowed mode:

bTopMostWindow=1

bMaximizeWindow=1

bBorderless=1

bFull Screen=0

iSize H=XXXX

iSize W=YYYY
