Drat these computers, they're so naughty and complex.

Upscayl: AI image resolution increase-er

Upscayl is not capable of adding detail especially in challenging lighting, so this photo is unmodified
Upscayl is a FOSS project that runs as an Electron application and utilizes a dGPU and machine learning to increase the resolution of photos, adding geometry via AI. I tried it out this weekend on a few old Facebook photos, and the results were interesting.
