For those messing around with shadow distance, I want to share my findings and current settings.
I was able to put the shadow distance up to 20000 (Ultra) and keep 60 FPS by doing the following.
Fallout4Prefs.ini (set to read-only)
- fDirShadowDistance=20000
- fShadowDistance=20000
- iDirShadowSplits=2
I also changed the world FOV back to 80 as per jorimt's suggestions above. It does make a difference but of course that means a FOV of 80.... Currently trying to find a way to make it stick with .ini commands, but I think it would be:
Fallout4.ini (read-only)
[Display]
fDefaultWorldFOV=80
fDefault1stPersonFOV=90
Put god rays on Low with everything else at Ultra.
I also used these tweaks found on reddit:
https://www.reddit.com/r/fo4/comment...ks_still_work/
Put these under [General] in Fallout4.ini (set to read-only)
uInterior Cell Buffer=24
uExterior Cell Buffer=288
bUseThreadedBlood=1
bUseThreadedMorpher=1
bUseThreadedTempEffects=1
bUseThreadedParticleSystem=1
bUseThreadedAI=1
bUseMultiThreadedFaceGen=1
bUseMultiThreadedTrees=1
iNumHWThreads=8
^I can confirm these made a difference of about 5-6 fps.
My specs:
4770k @4.0
MSI GTX980 no OC
16mb RAM
Win 10
Latest nVidia drivers
Borderless full screen
The area I tested was from the catwalks at the Corvega factory looking North (I think) over Lexington. Before these tweaks my frames tanked to 42 and everywhere in-between while finalizing the settings above, but now they're holding at 60 without compromising shadow distance. I'm going to play more tonight to see how it holds up.
