waifu2x-caffe VS arcomage

Windows version of the tool

I'd also recommend https://github.com/lltcggie/waifu2x-caffe/releases for a free upscaler.

Waifu2x in particular, is one of the oldest and still one of the best AI upscalers for anime and drawings in general, and it has always heavily favored Nvidia. The most known port was not the original Waifu2x by nagadomi, but Waifu2x-caffe, which was much more feature rich, and supported CUDA and cuDNN, both Nvidia exclusive. There was an OpenCL alternative which worked on AMD, but it was only as fast as Waifu2x-caffe under CUDA, but with cuDNN it still blew the OpenCL out of the water.

If u want a more detailed program you can look up their github and download it to upscale up to 10x it runs on both cpu and gpu cores so itl work on whatever pc you got. Just scroll down a bit. git hub

It's open source software just as many other projects on github are. Can't really help you translate, but the program is in many languages including English the author is just Japanese https://github.com/lltcggie/waifu2x-caffe If you scroll down you'll see some English text.

I used waifu2x, its client version https://github.com/lltcggie/waifu2x-caffe/releases. It is intended for drawn images, not realistic styles, but maybe you can find a use for this too since you use upscale in your workflow.

The settings I used for the original upscale (using waifu2x-caffe):

Since the project is open source, you can compile your own version using Godot 3.3.X, the alpha version 0.2 posted in the repository is incomplete, and I cannot recommend it for the game. I will post the current alpha version 0.3 there soon™. I need to tidy up the code, and bring some things to mind. If you want to test builds - please contact me, I will be very grateful to you. Also, if you know languages ​​other than English or Russian and want to start translating the game into your language - just contact me, I can share you a table with lines from the game.
