📋 About This Mod

This is a performance boosting mod originally released for Oldrim. Seeing that this fantastic mod had not been ported to SSE, I decided to port it myself. Below is a description of the mod taken from the Oldrim Page. I have received permission from RGabriel15 to port this mod.

This mod started as an attempt to improve the performance losses in some interiors when using Realistic Lighting Overhaul, up to version 4. 0. 6. Initially it was called Occlusion Culling Performance Patch (OCPP) on RLO page, but then I decided to expand things.

I started this new project with the goal to improve the performance in every interior as possible for everybody.

If you use highly demanding mods as Realistic Lighting Overhaul (RLO), Enhanced Lights and FX (ELFX) or ENB's then this mod is for you as it will give you some fps boost depending on your hardware. Even if you are not using any demanding mod or just playing the vanilla game, this mod will improve your performance.

In other words... this mod is a MUST if you want better performance in interiors for FREE!

Yeah, this mod don't remove anything from the game neither will make your graphics looks worse. You will play the game the way it is, but with more performance!

The mod consists of the following modules:

Skyrim Project Optimization - Full Version: The main module containing both Skyrim and the DLC's

SINCE THIS IS FOR SSE, IT IS ASSUMED THAT YOU HAVE ALL THE DLCs

I used a feature called Occlusion Culling, where I manually put occlusion planes in some spots of the interiors to improve performance.

What these occlusion planes do is un-render parts of the cell/objects/NPC's that are not being seen by the player, in most cases behind a wall or above/below floors (occluded).

Why make your hardware render things when they are not being seen, right?!

Occlusion Culling is an old technique used in lots of games including Skyrim, so don't worry about any damage to your hardware because what it does is the opposite:

If less things are being drawn on-screen at the same time, it means your hardware is using less processing power to achieve the same thing, and it automatically converts into better performance.

This mod is compatible with any mod out there, providing they don't add occlusion planes/cubes on the same interiors of my mod.

💡 Beginner Tips

  • Place this mod early in your load order (after the official DLC) to ensure it doesn't get overwritten by other mods that alter interiors.
  • If you use a mod manager like Vortex or Mod Organizer 2, let it handle the file placement — it's a simple drop-in mod.
  • Test performance in a few interiors like Bleak Falls Barrow or Dragonsreach to see the FPS difference before adding more mods.
