  3. Add or modify the following lines under [General]:
sIntroSequence=
fChancesToPlayAlternateIntro=0
uMainMenuDelayBeforeAllowSkip=0

Utilities[edit]

BethINI[edit]

BethINI is a .ini optimizer that also works as a configuration utility. It has well tested and optimized presets that could improve performance and fidelity.
Download BethINI[5]
  1. Download BethINI.
  2. Extract the contents and run BethINI.exe.
  3. In the Setup tab make sure Fallout 4 is selected as Game.
  4. In the Basic tab choose either Vanilla or BethINI presets and choose one of the available presets. BethINI presets are optimized and trimmed versions of Vanilla presets.
  5. Modify settings in each tab as desired.
  6. After finished click Save and Exit in the Basic tab, BethINI will sort your .ini files alphabetically and merge already existing tweaks in your previous .ini files.

Notes

It also supports other Bethesda titles such as The Elder Scrolls V: Skyrim Special Edition, Fallout 3, and Fallout: New Vegas.

Patches[edit]

Unofficial Fallout 4 Patch[edit]

A comprehensive bug fixing mod that aims to eventually fix every bug with Fallout 4 not officially resolved by the developers.

Mods[edit]

ENBoost[edit]

Fixes stuttering issues when there is no more available video memory, occurs when using high resolution texture mods.
Can force V-sync, includes a frame limiter to help prevent stutter.
Installing and Configuring ENBoost[citation needed]
  1. Download the latest version of ENBoost for Fallout 4.
  2. Unzip all files from the Patch folder in the archive into the installation folder. [See Notes]
  3. Open enblocal.ini with text editor, modify the following values:
  • ApplyStabilityPatch=[false/true] - Stability fixes, the effectiveness varies from user to user. If this worsens the performance, set to false.
  • UsePatchSpeedhackWithoutGraphics=[false/true] - Recommended to enable for maximum performance.
  • ForceVideoMemorySize=[false/true] - Allocates more video memory from RAM and the pagefile.
  • VideoMemorySizeMb=[RAM + VRAM - 300MB for SSDs, or the VRamSizeTest result - 300MB for HDDs] - [See Notes] Forces video memory available in Mebibytes.
  • ForceVSync=[false/true] - Different than the game's default Vsync, and helps prevent stuttering and screen tearing.
  • VSyncSkipNumFrames=[0, 1, 2, or 3] - Mainly for users with high refresh rate monitors (>60Hz) and should be set to '0' for other users.
  • EnableFPSLimit=[false/true] - Caps the frame rate to assigned value. This will solve the physics issues relating to high frame rates, may also solve screen tearing.
  • FPSLimit=[61.0] - The frame rate you wish to cap the game at.
  • DisableFakeLights=[false/true] - Disables rim lights for all characters. Has a small performance impact.

Notes

If you use ReShade or any other tool that uses the d3d11.dll file, rename that tool's DLL file to dxgi.dll.
If the game is installed on an SSD, do not use the VRamSizeTest utility, as it also allocates some HDD space, which can affect your SSD's life.
Use the VRamSizeTest utility if the game is installed on an HDD to correctly determine the amount of memory that can be allocated to the game.
Some users report that borderless windows setting along with frame limit increase FPS stability in the game.

Special K[edit]

Improves frame pacing, introduces texture caching system to reduce VRAM consumption, eliminates texture streaming bottlenecks and prevent memory fragmentation.

60 FPS
120+ FPS
Going above 120 will cause some major physics issues at higher frame rates. You may experience some between 61-120, but it's much more rare. If you must go over 60, lock the frame rate at 120 with something like RivaTuner.

Widescreen resolution[edit]

Modify Fallout4Prefs.ini[6]
  1. Go to the configuration file(s) location.
  2. Open Fallout4Prefs.ini.
  3. Under [Display] modify the following parameters:
iSize W=XXXX
iSize H=XXXX

Field of view (FOV)[edit]

Modify Fallout4Custom.ini[4]
  1. Go to the configuration file(s) location.
  2. Open Fallout4Custom.ini or create it if it does not exist.
  3. Under [Display] add or modify the following parameters:
fDefault1stPersonFOV=XX
fDefaultWorldFOV=XX

Notes

fDefault1stPersonFOV controls first person camera and PipBoy, fDefaultWorldFOV controls third person camera.
Modifying fDefault1stPersonFOV will also modify PipBoy's field of view which might be an undesirable side effect for some users. In that case consider using Flawless Widescreen.

Vertical sync (Vsync)[edit]

Modify Fallout4Prefs.ini[6]
  1. Go to the configuration file(s) location.
  2. Open Fallout4Prefs.ini.
  3. Under [Display] change iPresentInterval to 0.

Notes

Disabling vertical sync will cause frame rate to exceed 60 FPS which may cause physics issues and make the game unstable. See Frame rate capping.

Disable Depth of Field[edit]

Modify Fallout4Prefs.ini[citation needed]
  1. Go to the configuration file(s) location.
  2. Open Fallout4Prefs.ini.
  3. Find the following lines, and set them to these values.
bDoDepthOfField=0
bScreenSpaceBokeh=0

Notes

Will cause underwater effects to disappear.

SMAA[edit]

SMAA Anti-Aliasing with SweetFX[7]
  1. Download custom SweetFX 1.5.1
  2. Extract archive contents to executable location, and replace DLLs with ones from x64 folder

Notes

In-game TAA has a blurriness that disorientates some people. Injected SMAA gives a crisper picture, also has smoother edges than FXAA.

Issues unresolved[edit]

Crash to desktop during Hunter/Hunted[edit]

This issue blocks the continuation of a quest-chain.
Approaching the quest objective will result in a crash to desktop without any errors. As of current, if you wish to progress the quest-line, you will have to teleport into the related building and then teleport to an area that does not crash the game.
Teleport into building of interest to progress[14][15]
  1. Open the console and enter player.moveto 00064dfc.
  2. Walk around until character of interest spawns. Deal with the situation accordingly.
  3. When you're done with your business inside the building, open the console and enter coc sanctuaryExt.

Notes

You may walk freely within the building, but exiting it will crash the game.
Go into Steam offline mode and turn off internet connection (or block the game in firewall)

Entering Cambridge Police Station makes the player fall through the ground[edit]

This issue may block the continuation of a quest-chain.[15][16]
You may speak to characters inside the building if you enable noclip: open the console and enter tcl.
To exit the building afterwards, as the doors did not spawn in, you must teleport to another location, i.e. coc sanctuaryExt.
