📋 About This Mod

If you experience FPS dips down in the low 20s, try this out:

Add these in your Fallout4Custom.ini:

1. Go to your Fallout4Custom.ini in C:\Users\%username%\Documents\My games\Fallout4

2. Add these under the section:

bUseCombinedObjects=1

bUsePreCreatedSCOL=1

What does this setting do?

============================

1 = precombined meshes is globally enabled.

0 = precombined meshes is globally disabled.

This setting is hidden and default set to = 1 in Fallout4.ini.

Mods like Commonwealth Conifers Redux need precombined meshes to be disabled (=0) to make lush trees. A huge side effect of disabling precombinded meshs is massively increased draw calls which leads to lower performance.

Commonwealth Conifers Redux requires you to disable precomined meshes in the Fallout.ini file. If bUseCombinedObjects=0 exists in your Fallout4.ini, they will be overridden by the lines you just added in Fallout4Custom.ini.

Setting bUseCombinedObjects=1 enables precomined meshes and will improve performance, but will make the trees in Commonwealth Conifers Redux less appealing. Take a look at the 3 pictures at the top:

Picture 2 have precombined disabled and lush trees.

Picture 3 have precombined enabled and "normal" trees.

The FPS improvements speak for themselves...

Cleanup mods like Spring Cleaning will not work with bUseCombinedObjects=1 as Spring Cleaning needs precombined meshes disabled in order to work.

A mod can override Fallout4.ini files with their own ini files

====================================================================

Mods can add their own .ini files along the with the .esp/.esl/.esm files with overrides the settings in Fallout4.ini

I've included a tutorial in the .zip file with an easy way to find mod ini files that overrides bUseCombinedObjects in Fallout4.ini.

Example: Rustbelt Flora has 'Rustbelt Flora.esp' and 'Rustbelt Flora.ini' with the following setting:

bBorderRegionsEnabled=0

fPlayerDisableSprintingLoadingCellDistance=0

iMaxGrassTypesPerTexure=2

iMinGrassSize=10

  • Over 7,000 downloads show it's a go-to fix for many players.
  • Targeted tweak means you don't have to sacrifice visuals everywhere, just where it counts.

⚠️ Cons

  • Last updated in 2018—might not be fully compatible with the latest game patches or DLC.
  • Performance gains vary by system; 'double FPS' is a best-case scenario, not a guarantee.

💡 Beginner Tips

  • Make sure you've disabled any other mods that change the same ini settings to avoid conflicts.

  • If you're using a mod manager, install it manually by dropping the files into your Fallout 4 directory to ensure it overwrites correctly.
