https://github.com/mpv-player/mpv/wiki/User-Scripts#user-shaders There are 3 new shaders, how about adding a comparison between Anime4K and the new ones?

FidelityFX CAS AMD FidelityFX Contrast Adaptive Sharpening (CAS) provides a mixed ability to sharpen and optionally scale an image. The algorithm adjusts the amount of sharpening per pixel to target an even level of sharpness across the image. Areas of the input image that are already sharp are sharpened less, while areas that lack detail are sharpened more. This allows for higher overall natural visual sharpness with fewer artifacts.

FidelityFX FSR AMD FidelityFX Super Resolution is a spatial upscaler: it works by taking the current anti-aliased frame and upscaling it to display resolution without relying on other data such as frame history or motion vectors. At the heart of FSR is a cutting-edge algorithm that detects and recreates high-resolution edges from the source image. Those high-resolution edges are a critical element required for turning the current frame into a “super resolution” image. FSR provides consistent upscaling quality regardless of whether the frame is in movement, which can provide quality advantages compared to other types of upscalers.

NVIDIA Image Scaling NVIDIA Image Scaling is a spatial scaling and sharpening algorithm. The scaling algorithm uses a 6-tap scaling filter combined with 4 directional scaling and adaptive sharpening filters, which creates nice smooth images and sharp edges. In addition, an adaptive-directional sharpening-only algorithm is available. The directional scaling and sharpening algorithm is named NVScaler while the adaptive-directional-sharpening-only algorithm is named NVSharpen.
