📋 About This Mod
This mod started as an atempt 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 ENBs 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 dont 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: The main module containing only Skyrim without DLCs Skyrim Project Optimization - Full Version: The main module containing both Skyrim and the DLCs Skyrim Project Optimization - No Homes: The same as the main module but without the buyable homes. Skyrim Project Optimization - No Homes - Full Version: The same as the No Homes module but containing the DLCs Skyrim Project Optimization - Dawnguard: A separate module containing only the DLC Dawnguard Skyrim Project Optimization - Dragonborn: A separate module containing only the DLC Dragonborn

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 unrender parts of the cell/objects/NPCs 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 dont worry about any damage to your hardware because what it does is the opposite:

Skyrim Project Optimization is a performance mod that optimizes almost all interiors in Skyrim to improve FPS while keeping the game's visuals intact. With 76,004 endorsements and 2.2 million downloads, it's a highly popular choice for players seeking smoother performance without sacrificing the original look.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Massive community trust: 76k endorsements and 2.2M downloads show this is a go-to for performance.
- Simple goal, simple result: boosts FPS in interiors without changing how the game looks.
- Works for a wide range of setups—whether you're on a potato or a rig that just needs a little extra headroom.
⚠️ Cons
- Last updated in 2014—might not play nice with newer Skyrim versions or DLCs without patches.
- Only touches interiors—if you need outdoor performance, this won't help.
For Skyrim players who struggle with FPS drops in dungeons, caves, and buildings and want a quick fix that doesn't alter the game's look. Skip if you're on a high-end rig with no performance issues or if you need optimization for outdoor areas.
💡 Beginner Tips
- Since it's an older mod, check if you're using Skyrim Legendary Edition or Special Edition—this mod was made for the original, so you might need to find a port for SE.
- Install via a mod manager like Vortex or Mod Organizer 2 to keep your load order clean and easily disable it if issues arise.
- Pair with other performance mods like ENBoost for even better stability, but test in a few interiors first to see the FPS gain.
