Fallout 76 Custom ini Performance tweaks and improved load times.

Fallout 76 Custom ini file. Performance tweaks, improved load times and more with full details on what they do.

Keep in mind some of these tweaks will not work in the Fallout76Custom.ini

so you must edit them through the Fallout76Prefs.ini for some of them to work.

Such as iPresentInterval and sAntiAliasing seem to not properly disable in just the Fallout76Custom.ini alone, so it'll need to be changed in the Fallout76Prefs.ini as well. (Ctrl-F will open a search bar to find these quickly)

For further details and more performance tweaks scroll to the bottom.

To install the custom ini file add it to your Documents, My Games, Fallout76.

It should be sitting there with two other configuration files called

Fallout76.ini

 and

Fallout76Prefs.ini

 from there you're free to edit your

Fallout76Custom.ini

 and the Fallout76Prefs.ini

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Microsoft Game Pass Users should try my Project76Custom.ini first and if that doesn't work, try the method below...

Users will see Project76.ini so you must change the ini files name to Project76Custom.ini

If you don't have the Project76.ini issue, or if it keeps deleting itself and causing the error on start-up, you'll find the Project76.ini in your game directory where the .exe is. Copy and paste it to your Documents, My Games, Project76/Fallout76 folder and do that every time it deletes itself, setting it to read-only can help too.

Combining the Project76Custom.ini in to your Project76.ini will work without too many issues, some ini tweaks might not take effect and I haven't been able to test just how many, but pretty much everything will be working and mods will load.

Game Pass has many issues and is very frustrating to get to do what you want it to do, Steam is very simple to work with.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

To add mod files in, go to where the game is installed, the default location is usually the following...

Steam users add mods to C: Drive, Program Files (x86), SteamLibrary, steamapps, common, Fallout76 and add them to the 

Data

 Folder.

Microsoft Game Pass users add mods to C: Drive, Program Files, ModifiableWindowsApps, Project76 and add them to the Data Folder. (You will have to "give permission" every time you place a new file in, allow it to do so.)

To disable mods for any reason change sResourceArchive2List to sXResourceArchive2List

Simply by adding a letter or number to this line of text will break the games ability to read your mods, therefore disabling them quite easily for you.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Keep in mind the iPresentInterval set to 0 disables the in-game V-Sync, so to avoid any problems lock your FPS to 60 at the most, going above 60 can cause varying problems regardless of ones system.

It's inherently got an issue with the games engine being the Creation Engine / Gamebryo Engine where it doesn't like going above 60 FPS.

(Or you can change the 0 to a 1 and keep it enabled at a high performance cost.)

You can lock your FPS by going in to your NVIDIA control panel, or your AMD GPU application, add in the program Fallout76.exe, select your frame limiter and set it to 60.

If you want a form of V-Sync active I suggest activating it through your NVIDIA Control Panel, as for AMD users you can do the same though I don't know how well AMDs V-Sync handles.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Optionally for additional performance you can enter the Fallout76Prefs.ini and change the lines fShadowDistance=12000. 0000 and fDirShadowDistance=12000. 0000 this will lower your shadow draw distance to 1200 meters (12000. 0000) over the default low setting of 6000 meters (60000. 0000).

I even suggest doing this even on high end hardware, regardless of what you're running.

You can increase or decrease the number as you wish or even set it to 0.

The grass max distance is 7000. 0000 (700 Meters) so you can make the shadows identical or lower if you please.

fBlendSplitDirShadow=512. 0000 or =256. 0000 This setting will increase the draw distance of the low resolution shadows making the pop-in far less noticeable from Low Res to High Res making it so you only see High Res Shadows as you walk, the default high number is =48. 0000, this setting is also changed in Fallout76Prefs.ini

Specifically the shadow resolution circle around the player is what this affects, minor thing that most people don't or won't notice.
