Tweaking FalloutCustom.ini:
- Make sure the Viva New Vegas - Core profile is active
- Click the
button on the top bar of MO2 and select INI Editor - Navigate to the FalloutCustom.ini tab, which should be blank
- NOTE: Make sure you are in the FalloutCustom.ini tab and NOT the Custom.ini tab
- Paste the following into the box:
- [General]
- bUseThreadedAI=1
- INumHWThreads=4
- bPreemptivelyUnloadCells=1
- [BackgroundLoad]
- bBackgroundCellLoads=1
- bSelectivePurgeUnusedOnFastTravel=1
- [Display]
- bFull Screen=1
- iPresentInterval=0
- [Controls]
- fForegroundMouseAccelBase=0
- fForegroundMouseAccelTop=0
- fForegroundMouseBase=0
- fForegroundMouseMult=0
- fXenonVertLookSpeed=1200.0000
- fXenonHorizLookSpeed=1500.0000
- [Grass]
- fGrassStartFadeDistance=7000
- [Audio]
- iAudioCacheSize=8192
- iMaxSizeForCachedSound=1024
- [Archive]
- SArchiveList=Fallout - Invalidation.bsa, Fallout - Textures.bsa, Fallout - Textures2.bsa, Fallout - Meshes.bsa, Fallout - Meshes2.bsa, Fallout - Voices1.bsa, Fallout - Sound.bsa, Fallout - Misc.bsa
- Change INumHWThreads to the number of threads your CPU has
- If you do not know how many threads your CPU has, use CPU-Z to find out
- fXenonVertLookSpeed and fXenonHorizLookSpeed can be removed if you do not run the game in a 16:9 aspect ratio (common 16:9 aspect ratio resolutions include but are not limited to 1920x1080, 1600x900, and 1366x768
- The SArchiveList tweak is only needed if you used the BSA Decompressor from Core - Tools. Make sure the entire list of archives is on one line in the INI
- Repeat for the Testing profile
| Tweak | Effect |
|---|---|
| bUseThreadedAI=1 | Allows AI to use threads to increase performance |
| INumHWThreads=4 | Allows the game to better utilize the CPU |
| bPreemptivelyUnloadCells=1 | Helps prevent Out of Memory crashes when changing cells |
| bBackgroundCellLoads=1 | Streams in assets to prevent stuttering at the cost of objects sometimes suddenly popping in |
| bSelectivePurgeUnusedOnFastTravel=1 | Helps prevent Out of Memory crashes when changing cells |
| bFull Screen=1 | Ensures the game runs in fullscreen mode |
| iPresentInterval=0 | Disables V-Sync, as when enabled it can cause noticeable lag in menus. You can set this to 1 if you would rather have menu lag than potential screen tearing |
| fForegroundMouseAccelBase=0 fForegroundMouseAccelTop=0 fForegroundMouseBase=0 fForegroundMouseMult=0 |
Disables mouse acceleration |
| fXenonVertLookSpeed=1200.0000 fXenonHorizLookSpeed=1500.0000 |
Sets the mouse sensitivity of the x and y axes equal to each other |
| fGrassStartFadeDistance = 7000 | Increases the distance at which grass disappears from 3 cells to 5 cells |
| iAudioCacheSize=8192 iMaxSizeForCachedSound=1024 |
Increases the audio cache to prevent stuttering and audio not playing |
| SArchiveList= | Adds the BSAs created by the BSA Decompressor to the list of BSAs loaded by the game |
INI Settings to not change:
uGridsToLoad=5: Changes the amount of cells loaded at once. When changed, it can cause scripts to run when they aren't supposed to, will ruin performance, and will break your game if changed on an existing save
INumHavokThreads=1: Any changes to it are placebo in regards to performance, can cause instability if set over 2
bUseThreadedBlood/Morpher/TempEffects/ParticleSystem=0: Setting any of these to 1 is placebo and will not affect performance
