Description

Welcome to the complete optimization for the Skyrim's BSAs!

Skyrim (and all Bethesda games) uses the BSA format to store all the game data (textures, models, voices...). The BSA Optimization Project wants to improve those files and the way the game works with them, in order to achieve a better performance.

Read all the description carefully before installing



The BSAs are compressed files. When Skyrim needs to read the content inside, the CPU needs to unzip them first, process the content and then, show it in your screen. Using BSAOP, your CPU doesn't need to unzip it. I repacked all the vanilla files inside the BSAs but I didn't compress them, so the CPU reduces its work in half. In my setup (that does have a processor that doesn't meet the minimum requiriments, 2.13 GHz x 2), that helped me to remove the stuttering and reduce script lag in most areas. Anyway, the results will vary from system to system, so just try and see how it works for you!

BSAOP has different flavours that can help you achieve an even better performance. Read below:



This mod has 4 different versions. The black one is the version you are currently looking at.

Vanilla versions
These versions keep the game exactly as vanilla. No textures, no meshes were optimized or modified. These versions should give you reduced stutter and less script lag, as the CPU doesn't need to unzip the files before reading them.

- BSAOP - Skyrim's BSAs: Check here!
- BSAOP - High Resolution DLC BSAs: Check here!

Performance versions
These versions has optimized textures (thanks to the STEP team and tony971). These textures should reduce your VRAM usage and make the overall game run better. They are recommended over the Vanilla versions, but take in mind that the vanilla files were modified. If you see purple textures, broken textures and so on, switch to Vanilla versions.

- BSAOP - Skyrim's BSAs Performance:(This is the best one in my opinion!) Check here!.
- BSAOP - High Resolution DLC BSAs Performance: Check here!

Here is an useful table regarding compatibility between versions if you are using two versions together:

Make sure you uninstall first the official High Res DLC before installing the BSAOP High Res versions!. Also, uninstall any flavour before switching to another one, following the instructions inside the flavour's description



Go to the flavour description and read the steps there :)



BSAOP is compatible with, literally, EVERYTHING. It just  overwrite all the BSAs from the game. That means that mods and another things added by the player will overwrite BSAOP. Just treat the game as vanilla (as if BSAOP isn't installed).
Anyway, make sure that you install the flavours correctly.




Go to the flavour description and read the steps there :)

Bethesda Softworks, for this incredible game, the assets used and the Archive.exe (from Creation Kit), used to repack the files.
SkyrimTuner and Ghostifish, because I used their source code as a base for adapting and updating the installer/uninstaller scripts for BSAOP. Thank you very much!
Tony971 and the S.T.E.P team, for his amazing optimized textures. Without them, the performance versions of BSAOP wouldn't exist.

I figured out how to fix the missing texture glitch.

What you need to do is to go into the properties folder for skyrim, go into the data folder, and delete all BSAOP files there. When you return to skyrim, the textures will be working.

Whenever you subscribe to any of these four mods, the file is placed into the data folder. So even after unsubscribing to the mod it still messes with any other ones you subscribe to.

Oh, I'm glad you liked it! It's really good to hear that you finally fixed it! Enjoy the mod!

Nevermind I fixed it. The version of SkyUI I was using was old and unoptimized.

I did a clean reinstall of the latest version and it's back to normal. Thanks for this mod though! It really has helped clean my game up and greatly boosted my load times. Favorited and liked for sure!

Conflict how? It shouldn't. Did you follow properly the instructions for installing it?

Hello, I just installed the Normal BSAOP mod and it seems to conflict with the mod SkyUI, Is there any way to fix this?
