Root Mods

Use the Manual Download and follow the instructions provided for each mod.

Failing to install these mods correctly will result in issues.

Game Patchers

Each version of the game requires a different patcher to work with xNVSE.
These patchers allow the game to use up to 4GB of RAM and automatically load xNVSE.

Custom INI

In this step we will take advantage of JIP LN NVSE's FalloutCustom.ini feature to improve performance and stability without affecting the main INIs.

1. Click the button at the top of MO2 and select INI Editor.
2. Select the FalloutCustom.ini tab, which should be blank. In case it's not, clear the file.

If you don't see the FalloutCustom.ini tab, then you have not enabled profile-specific Game INI Files in Profile settings during MO2's configuration.

3. Paste in the following:
; Value types (prefixes): ; i = integer (whole number) ; f = float (decimal number) ; s = string (text) ; b = boolean (0 = Off, 1 = On) [Audio] ; Enables additional worker thread for minor performance improvement bMultiThreadAudio=1 ; Disables debug logging to save memory and CPU time bUseAudioDebugInformation=0 ; Increase audio file cache size to reduce loading stutter iAudioCacheSize=16384 iMaxSizeForCachedSound=2048 [BackgroundLoad] ; Forces cell unload on fast travel to lessen memory usage bSelectivePurgeUnusedOnFastTravel=1 ; Reduces stutter when loading multiple NPCs bBackgroundLoadLipFiles=1 [Controls] ; Disables mouse acceleration in menus ; Game does not have mouse acceleration for the camera fForegroundMouseAccelBase=0 fForegroundMouseAccelTop=0 fForegroundMouseBase=0 fForegroundMouseMult=0 [Display] ; Enables Fullscreen mode for the best performance in D3D9 ; Refer to the Performance Guide for more info bFull Screen=1 ; Use this for V-Sync control (the Launcher setting doesn't work) ; 0 = Off, 1 = On, Higher values toggle fractional V-Sync (not recommended, very laggy and disables Variable Refresh Rate) iPresentInterval=1 ; Forces highest texture quality so textures won't break if you had it set to anything lower iTexMipMapSkip=0 ; Disables actor shadows due to their low visual impact and high performance cost bDrawShadows=0 iActorShadowCountInt=0 iActorShadowCountExt=0 ; Camera FOV fDefaultWorldFOV=75.0000 ; Viewmodel FOV fDefault1stPersonFOV=55.0000 ; Pip-Boy and terminal FOV fPipboy1stPersonFOV=47.0 [General] ; Forces faster cell unload to lessen memory usage bPreemptivelyUnloadCells=1 ; Spreads AI and game logic updates across 2 threads for better performance ; Values above 3 don't change anything, and the setting has nothing to do with the number of CPU cores iNumHWThreads=3 ; Tale of Two Wastelands specific ; Sets TTW's starting quest SCharGenQuest=001FFFF8 ; Disables FNV intro movie SIntroMovie= [Grass] ; Increases grass draw distance fGrassStartFadeDistance=11200 ; Ensures that 3.0 Vertex Shader is used. ; Allows drawing more grass with better performance b30GrassVS=1 [PipBoy] ; Fixes flicker when opening Pip-Boy when its light is on fLightEffectFadeDuration=400

Testing Utilities

1. Restart your PC (otherwise some plugins might fail to load).
2. Install the ML Utilities Checker with Mod Organizer 2, just like the previous mods.
3. Launch the game using the Tale of Two Wastelands option in MO2 (not NVSE).

4. If you see a black console window appear, it means NVHR is working.
5. Once the game has reached the main menu, wait a few seconds and you will see a message box from the Utilities Checker.
   If any check fails and the comment doesn't help you find a solution, open a support thread in the ModdingLinked Discord server.
6. Close the game and disable the ML Utilities Checker.
