What should happen

Hello, I hope you are having a good day. Well, there is a very interesting function that I saw in another emulator and I want to share it with you and see what you think.

It is about Contrast Adaptive Sharpening, it is a function that gives and a feeling of increased resolution and graphic improvement WITH SHARPNESS without loss of performance.

Examples: image image

CAS was an older alternative to AMD's newer FSR algorithm. I don't think it's that interesting for us since our per-pixel shading cost is low - crank up the resolution instead, or even better switch to Vulkan and use MSAA 8x to get the sharpest possible image with great antialiasing.
