The texture files from the original mod were mostly 2K in BC1 or BC3 compression. I have cleaned all files of compression artifacts caused by these older compression formats, and then upscaled them all by 4x, to a maximum resolution of 4K and generated full mipmaps. I cleaned and upscaled them using Cupscale/ESRGAN and then finalized with NVIDIA Texture Tools and Octagon. 

Requires the original mod; overwrite with this one.
Uses the same FOMOD as the original, so if you want to use the custom options then just make sure to select all the same options during the FOMOD installation.

Performance Options for Potato PCs
Mipmaps reduce VRAM usage, especially when the files are cleaned of compression artifacts.
For Potato PCs, I've uploaded a downscaled version where the diffuse texture files are larger than normal and environment map files, which are less visible in game. This reduces VRAM usage considerably while maintaining higher visual quality, using the Octagon config files posted on this mod, which I recommend using if you have a Potato PC.

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.
