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!

I used a feature called http://en.wikipedia.org/wiki/Hidden_surface_determination, 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:

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

To see a list of places optimized with this mod, look here: http://skyrim.nexusmods.com/articles/982/

Im preparing an ARTICLE to better ilustrate how it works.

This mod is compatible with any mod out there, providing they dont add occlusion planes/cubes on the same interiors of my mod. As far as i know, theres not a single mod out there that add occlusion to the game, so my mod is 100% compatible with any mod!.

IMPORTANT: If you are using the Occlusion Culling Performance Patch (OCPP) that was previously available on Realistic Lighting Overhaul page, you must remove that mod and use this improved version.

JUST MAKE SURE TO PUT IT ON THE CORRECT LOAD ORDER!!!

As my mod add objects (occlusion planes) to Cells, it could revert other mods changes (like lighting, fog, etc) back to vanilla. Aware of that, i made the plugin as a master (.esm).
All you need to do is load my mod just after the game and DLCs .esm files and before any mod .esm or .esp. That way you will ensure other mods overwrite my mod and have no conflicts.

EXAMPLE:

CORRECT LOAD ORDER:

A correct load order with my mod being loaded after main .esm files and before Climates of Tamriel.esm and other mods.

Skyrim.esm
Update.esm
Dawnguard.esm
Hearthfire.esm
Dragonborn.esm
Skyrim Project Optimization.esm
Climates of Tamriel.esm
other .esp plugins

INCORRECT LOAD ORDER:

A incorrect load order with my mod being loaded after main .esm but after Climates of Tamriel.esm.

Skyrim.esm
Update.esm
Dawnguard.esm
Hearthfire.esm
Dragonborn.esm
Climates of Tamriel.esm
Skyrim Project Optimization.esm
other .esp plugins


IMPORTANT: Sometimes, mods you recently added to your game will not work. To fix this bug, after you install the mod, open the Launcher, disable the mod and close the Launcher. Open the Launcher again, enable the mod and put it on the right load order. This will fix mods not loading.

My next updates will consist of 4 steps:

Minor Cities and Towns: Where i will update the main module with the remaining interiors of Skyrim
Dawnguard: Where i will release a separate module with all Dawnguard interiors.
Hearthfire: Where i will release a separate module with all Hearthfire interiors (if needed).
Dragonborn: Where i will release a separate module with all Dragonborn interiors.

Here are some of the mods i use and recommend:

http://skyrim.nexusmods.com/mods/29253: What it does is to remove the ambient fog on all interiors, making them darker and more realistic.

http://skyrim.nexusmods.com/mods/30450: That is the mod with the most realistic lighting on Nexus. It completely overhaul the lighting system and fixes a lot of bugs with lighting and shadows.

http://skyrim.nexusmods.com/mods/1111: One of the best water mods for Skyrim, if not the best.

http://skyrim.nexusmods.com/mods/8655: That mod fixes a lot of ugly meshes and textures present in vanilla game A MUST!
