An addon for my mod Cleaned Skyrim SE Textures - Performance Optimized that tackles all Creation Club content included with Anniversary Edition.

Kartoffel did a great job making Creation Club Anniversary Cleaned and Upscaled which features vanilla textures cleaned of compression artifacts, bad bicubic upscaling removed, and other random fixes applied. If your system can handle it, you should run that.

If you're reading this, however, you're probably interested because your system is a bit of a potato.
Well, don't worry, as I'm here to help serve every type of potato, and hopefully make Skyrim a bit more accessible.

In addition to using Kartoffel's Cleaned Textures as a base instead of Bethesda's original textures, this mod differs in that it treats diffuse texture files differently from normal maps, specular files, and other types of textures that are less visible.

I used Octagon for texture processing, with modified settings from WillOhTheWisp

How cooked is your potato??
Below are the Maximum Resolution of All Files in 'Diffuse/Maps' for different versions of the main files.
You can choose whether you want loose files (no plugin) or a compressed bsa with an esl-flagged plugin

For Baked Potatoes
You mostly run Vanilla Skyrim fine, but get FPS plunges outdoors and in heavy engine moments.
Everything: 2k/1k

For Mashed Potatoes
60 fps? What's that!? 
Everything: 1k/512

For Potato Soup
Your friends question whether your old crappy laptop can run any game at all (don't listen), but you're insistent and XilaMonstrr keeps egging you on (do iittt)
Everything: 512/256

Installation
Put high up in your load order, shortly after USSEP and Cleaned Skyrim SE Textures - Performance Optimized, and before any other mods with textures.

If you are interested in collaborating on Overhaul projects, or levelling up your experience of modding Skyrim, please join my discord server, Skypocalypse.

Skypocalypse is above all a place for COLLABORATION, a community hub for mutual aid to level up our skills and Skyrim itself.
 
This server is the host to Skypocalypse Academy, where modders and porters of all skill and experience levels assist each other as we dive ever deeper into transforming the bones of this magical game. Featuring an extensive library of tools and resources, The Academy is meant to be as educational as it is welcoming.
 
We know from experience that modding is an extremely addictive past-time and can be a slippery slope from creating a simple load order to porting mods to going full boat and attempting to rebuild Skyrim from the ground up. That's why we believe in a community that integrates Xbox and PC gamers along with porting noobs and experienced mod authors. We all have more to learn, and modding Skyrim to its extreme is a community effort to say the least.
 
Skypocalypse is meant to be a gaming community that supports collaborative efforts. The gaming and social channels here are intended to foster the social connections that help act as glue for our collaborative work.[/size]
