Navigate to /Documents/My Games/Fallout 76
Make a copy of Fallout76prefs.ini, and rename it to Fallout76Custom.ini
Delete the entire contents of that file, so you just have an empty Fallout76Custom.ini file that you can edit in notepad.
Any changes made in this file will over rule any other .ini in that folder, and the launcher/updates shouldn’t mess with it.
Here are my changes:
[Display]
bFull Screen=1
bFullScreen=1
bBorderless=0
(Not honestly sure why I have two or which one is correct. These changes force true Fullscreen mode, which should fix all frame hitches/issues so long as your hardware is sufficient to actually play the game.)
fDOFBlendRatio=0
fDOFMinFocalCoefDist=999999
fDOFMaxFocalCoefDist=99999999
fDOFDynamicFarRange=99999999
fDOFCenterWeightInt=0
fDOFFarDistance=99999999
(These are HALF of what you need to turn off DOF effectively, and create a really clear game. These also go under the [Display] header. The minimum distance is 6 9’s, every other value is 8 9’s. Below is the second half.)
[ImageSpace]
bDoDepthOfField=0
bDoRadialBlur=0
iRadialBlurLevel=0
bMBEnable=0
bLensFlare=0
bScreenSpaceBokeh=0
bDynamicDepthOfField=0
(That’s the second half, they go under header [ImageSpace]. One of these entires also turns off lense flare, because your eyeballs aren’t cameras.)
I also use:
[SaveGame]
fAutosaveEveryXMins=2.0000
(In my experience, this entry has made my auto save interval much quicker. When I logged in with teamviewer today, I was basically standing right outside the place where I was when the beta closed. Previously I could have been up to 10 minutes gameplay back it seems, the default value is 10.0000)
To adjust Field of View, add these two lines under [Display]
fDefault1stPersonFOV=90.00
fDefaultWorldFOV=90.00
Replace with whatever value you want, I’ve seen people put it up to a whopping 110 with no apparent issues, however be warned as the devs say adjusting the field of view can cause animation or clipping issues.
Also, I am definitely not the person who found any of these, I just copy/pasted my comment to someone else asking how to do it, and figured I might as well share it. If you’re the person who discovered these fixes, please let me know and I’ll edit in credit for you.
Edit:
Under
[Display]
you can also add
sAntiAliasing=FXAA
The game uses TAA or Temporal Anti-Aliasing by default for some reason, it’s a setting Bethesda uses in their Virtual Reality games. This should change it to FXAA or Fast Approximate Anti Aliasing.
I haven’t tried SMAA, if anyone wants to give that a go and let me know if it works that’d be great, I’m still at work for a few hours. :
Edit 2:
credit /u/Caviac, to normalize vertical sensitivity, add these lines to Fallout76Custom.ini
[Controls]
fMouseHeadingXScale = .021
fMouseHeadingYScale = X
Where X is any of these values, based on your Aspect Ratio
.03738 for 16:9
.042 for 21:9
.028 for 4:3
.0336 for 16:10
edit 3 and 4:
credit /u/derhermann
To disable Mouse Acceleration, use:
[Controls]
bMouseAcceleration=0
To disable Grass use:
[Grass]
iMinGrassSize=1
bAllowCreateGrass=0
