The new upscale shader, CUT3, has been released for retro and modern games. Developed by Swordfish_90, this shader allows users to adjust the sharpness or smoothness of edges, offering customizable visual enhancements. It is designed to work with various emulators, including Retroarch, though some adjustments are needed for compatibility

Looks nice on games with simple graphics, but I’d still never use it on pixelated games.
Oh hey, it’s by the same guy that made Lemuroid!
