For the best performance, just install the new patch of game then lasted driver of your VGA.
After that head to your Fallout 4 at your document folder then open the Fallout4pref.ini
Edit these lines:
iShadowMapResolution=512
uiShadowFilter=3
uiOrthoShadowFilter=3
fBlendSplitDirShadow=999999.0000
iMaxFocusShadows=0
iMaxFocusShadowsDialogue=0
fShadowDistance=0.0000
fDirShadowDistance=0.0000
iDirShadowSplits=1
----------------------------------------------------
so It gotta be done now, the shadow would be completely disabled without flkering
My fps increase like missle run out the cannon :v
-----------------------------------------------
I suggest combinding this tweak with
Wastenland 512
LOD distance scale (or something like that)
Vanilla texture optimized
and
the resort patch
