Someone had requested this so here it is.
This:
I upscaled textures of Thunderchild - Epic Shouts with ESRGAN models. On request.
Is this a flawless masterpiece?
No, this is something my computer did while I did stuff because computer smart.
Kartoffel, does this really need to be 4x?
Sure why not?
Requirements:
Skyrim Special Edition - wow
Thunderchild - Epic Shouts and Immersion
Process:
All textures: Remove BC1-3 compression with Bc1-smooth2 model.
All textures: Upscale 4x with manga109 model.
All textures: Compress to BC7.
Resolution:
4x: Max image resolution is 4k.
1x: Just cleans the artifacts.
Difference of block compression BC1, BC3, and BC7:
In dds texture (the textures skyrim uses), compression via BC1, and BC3 (with alpha), is blocky. Because of this, in original Skyrim, people sometimes leave textures uncompressed. Uncompressed has a big file size.
With the new block compression, via BC7, it is nearly the same quality as uncompressed, but has the same size as BC1, and BC3. However, this is only supported in Fallout 4 and Skyrim SE.
So even If I do not upscale, by removing BC1-BC3 artifacts and compressing as BC7, the quality is improved.
TLDR: Even without upscale, there is big difference. NO MORE BLOCKY! @400% zoom, so you can see the difference.

Compatibility:
Cannot use with Skyrim Legendary. See "Difference of block compression" above. If you change this BC7 -> uncompressed or BC1, BC3; then, it will work. Use Cathedral Assets Optimizer.
Permissions:
I don't care.
