This mod gives you some first information about ini changes for better graphics.
I'm still testing, but got rid of a lod of lod and object plopping, denser grass, more view distance on everything.


Go to

X:\Users\YourUserName\Documents\My Games\Fallout4 with X standing for your harddrive.

There we got Fallout4.ini and Fallout4Prefs.ini you can open both with any texteditor like wordpad, Editor...
Make a copy of both, just to be sure as backup.
Had no problem doubling everything (that should be doubled, see description) and setting shadows to 8192 on a geforce 970 without stuttering at all.

Fallout4.Ini:


[General]

uGridsToLoad=5 
Enhancing this to values like 7,9,11,13 improves the farther away landscape. But it's dangerous, skyrim had a lot of problems and bugs with it and you needed a savegame cleaner to go back down.
7 worked without problems, but be aware of the problems that could occure.

uExterior Cell Buffer=36
Maybe the same rules as in Skyrim, but as the engine is improved it might be different.

[Display]

fShadowLODMaxStartFade=1000.0
Draw distance for shadows on far away objects. 10000 or 20k seems to work.

fSpecularLODMaxStartFade=2000.0
Darw distance for lighting on far away objects. 10000 or 20k seems to work.

iShadowMapResolutionPrimary=2048
Your primary shadow resolution enhance to 4096 or 8192. 8192 works fine for me

fSAORadius=108.2
fSAOBias=0.6
fSAOIntensity=7.1
Sounds like Ambient Occlusion distance, intensity and Bias.

[SSSSS]

fSSSSSPower = 4.0
Probably subsurfacepower, enhancing this to 5 could give people less of a dead look. Needs testing.

[Interface]

fDefaultWorldFOV=70
fDefault1stPersonFOV=80    Change your field of view

[Grass]

iMinGrassSize=20
Setting this lower should give you denser grass.

[Water]

bReflectLODObjects=0
bReflectLODLand=0
bReflectSky=0
bReflectLODTrees=0
1 activates the reflections.



Fallout4Prefs.ini

[Display]

fDirShadowDistance=20000.0000
fShadowDistance=20000.0000
This could work like in skyrim, higher values could increase the range, but decrease the quality near you. Wouldn't change it yet.

iShadowMapResolution=4096
Again shadow resolution, change to 8192

fLeafAnimDampenDistEnd=4600.0000
fLeafAnimDampenDistStart=3600.0000
Leaf animation range

fMeshLODLevel2FadeTreeDistance=2048.0000
fMeshLODLevel1FadeTreeDistance=2844.0000
Distance and levels for tree meshes to dissppear, just enhance a few thousand

fInteriorMeshLODLevel2FadeDist=1950.0000
fInteriorMeshLODLevel1FadeDist=2600.0000
Range for interior meshes to degrade in quality and disappear. With both at 5000 you are probably save.

iMaxSkinDecalsPerFrame=25
iMaxDecalsPerFrame=100
Name says it, can probably go a lot higher.

[General]
uGridsToLoad=5
Same as above, should be the same value.

[Particles]
iMaxDesired=750
Higher the better

[TerrainManager]
fTreeLoadDistance=75000.0000
fBlockMaximumDistance=250000.0000
fBlockLevel2Distance=110000.0000
fBlockLevel1Distance=90000.0000
fBlockLevel0Distance=60000.0000
Display ranges for trees and objects. Just enhance proportionate. Doubling worked for me.

[Grass]
fGrassStartFadeDistance=7000.0000
fGrassMaxStartFadeDistance=7000.0000
fGrassMinStartFadeDistance=1000.0000
Display range for grass. 25000 works for me

[Decals]
uMaxDecals=1000
uMaxSkinDecals=100
Higher=better

[LOD]
fLODFadeOutMultObjects=30.0000
fLODFadeOutMultItems=10.0000
fLODFadeOutMultActors=15.0000
Probably Lod ranges for those to disappear.


Activate write protection afterwards, just to be sure.
