Attention: This is a heavy process that requires a powerful computer. Do not use the computer while doing the upscale as ESRGAN uses all the resources of the PC during the process. If you open a game or app your pc will probably not stand it and will restart or will simply give an error in the upscale.

What is ESRGAN?
An artificial intelligence capable of improving the quality of images. It is currently being used a lot to improve textures of old games and to improve the quality of drawings, films and anime.

About ESRGAN Models:
The .pth models that can be downloaded from the Model Database
Also https://nmkd.de/?esrgan , Game Scale Discord, Upscale wiki etc.

Pack de 72 modelos para ESRGAN:
Download

Each model has a different function, there are models that upscale terrains, models that upscale drawings, etc. Read the page carefully and see which model is best for you.
To upscale old game textures before anything else it is essential that you use the "BC1 smooth 2.0 "model to correct compression artifacts and then the "1x_ordered_dither "to correct the coloring of the texture to just do it there ' 'upscale real' '.

1 - Download and run Cupscale

2 - In the upper right corner of it there is a gear icon, click on it.

In ''Models Path'' select the folder where your ESRGAN models (.pth) are located.
Note: You can create subfolders and organize models by categories like ''drawings'' ''realism'' etc.

3 - Select ''AI Settings'', then we have 3 tabs: Pytorch, NCNN and NCNN.

Pytorch:
In ''Python Runtime'' you can choose two options: ''Use System Python'' which will make Cupscale use Python installed on your pc (don't forget to install pip, openCV and pytorch in this case) or ''Use Embedded Python if Available'' which will use the ''portable python'' downloaded by Cupscale (more on this later).
I recommend Embedded Python as it is simpler to install.
In ''Seamless Mode'' you can choose the repeat mode of a texture, select ''Repeat: Tile'', this will work for most cases. Note: Not every texture in a game is seamless, for example weapons aren't usually seamless, remember to disable seamless mode if you're going to upscale an image of this type. There is a shortcut to seamless mode on the left side of the program.
On NCNN and NCNN simply leave ''auto'' in ''tile size''.

4 - In ''Resource Files'' click on ''Open Dependency Checker'', this will show if your pc has what it needs to use ESRGAN.
Click on ''Embedded Python Installer'' and select ''Install''. After that return to the ''Open Dependency Checker'' to see if the dependencies are already correct.

5 - In the left menu, under "Model 1: "click on the box below, this will open a menu with the ESRGAN models for you to choose, select one and click on "Select Model"

6 - Place all the images you want to apply upscale in the same folder, then drag this folder into Cupscale. This will take you to the "Batch Upscale "menu, in it, in "Output Directory "select the folder where you want to save your images, in "Overwrite Mode "select "Yes - Don't Add Suffix "and finally click on "Upscale * Images"

Nice work! I couldn't find 1x_ordered_dither.pth where is it?
