1.Go to "Documents\My Games\Fallout4" and open the file "Fallout4.ini" and edit the following line:

2. Find:
sResourceDataDirsFinal=STRINGS\

3. Change to:
sResourceDataDirsFinal=STRINGS\, TEXTURES\, MUSIC\, SOUND\, INTERFACE\, MESHES\, PROGRAMS\, MATERIALS\, LODSETTINGS\, VIS\, MISC\, SCRIPTS\, SHADERSFX\

4.Extract this file in the Fallout 4 main folder, replacing any existing file.

E.g.: For steam: (Steam/SteamApps/common/Fallout 4)

Open the game and see if it works, if not, try the following:

You will need to add the following line to the Fallout4Prefs.ini file below the sections

[Launcher]
bEnableFileSelection=1


In the Fallou4.ini file, make sure this is set to 1

[Display]
iPresentInterval=1


If that still doesn't do the trick, do the same thing you did in the steps 1 to 4, but in the Fallout4Custom.ini file.

If everything fails, you must have done something wrong like extracting to the wrong folder. Double check all the Folder Paths.
