Preface

This mod is the logical answer to Optimized Room Bounds and Portals and has been a personal dream of mine since mod Fallout 4. Now that it's finished and ready to test, I can tell you that it's been my GOAT experience since playing FO4!

This mod gets rid of the huge reference manipulation on the outer cell headers and simply leaves the references empty, the result is that the game now loads uGrid 5 in real time and all object rendering is real time.

At first I wasn't sure if it would slow down performance and how much worse it would be...but no, BC City Center ran super stable, no microstutters, nothing. Never mind. . . I got almost 60 FPS on the Corvega using the iGPU at high to ultra-high settings. There was almost no microstuttering until I was about 30 or 40 years old, probably doomed by the huge combo grid loading in the background.

I've tested it using a mod in my load order, this one. It must be loaded at the very bottom of your load order! Therefore, please be sure to read the following precautions carefully.

Overview

In short, this mod...

  • Affects external cells
  • Change PreVis

⠀- Blank PreVis File Timestamp (VISI) ⠀-

Blank PreVis Reference Index (XPRI)

  • Change PreCombination

⠀ - Blank PreCombined File Timestamp (PCMB)

⠀- Blank Combined Reference Index (XCRI)

  • Unmarked static objects: "[Place Object]" to "Place Object", which in turn allows any mod author to change any object without worrying about breaking anything, now you can actually modify the game ;)
  • Improve performance

⠀- Occlusion markers as these alone can improve performance but are a hell of a job

⠀ - SCOL will be added later to the skyscrapers in downtown Boston, which will further increase rendering as SCOL reduces object count/draw calls (!), if you're curious, go into CK and …

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
