[feature request] postprocess antialiasing & adjustable sharpening

[ThomasSteve83]

fsr is supposed to be used on top of existing antialiasing, which vanilla minecraft and many shaders lack

so, for use with fsr, maybe implement fxaa and/or smaa

antialising on its own usually makes an image less sharp, and while i'm pretty sure fsr implements cas, it's not adjustable, and isn't available without fsr

so, maybe seperate cas from fsr and make it configurable

WRONG, sir. Only BAD antialiasing reduces sharpness. Good AA, like MSAA and SSAA aims to remove aliasing by restoring missing information, which will only improve overall image sharpness if you think about it.

WRONG, sir [1]. Only BAD antialiasing reduces sharpness. Good AA, like MSAA and SSAA [2] aims to remove aliasing by restoring missing information [3], which will only improve overall image sharpness if you think about it [4].

[1] *m'am

[2] neither msaa nor ssaa is applicable to the case i'm addressing here, which is upscaling with fsr

[3] msaa and ssaa don't exactly restore missing information, but rather include it from the start (at a significant computational cost) (by rasterizing and/or shading some or all of the frame at a higher resolution and then downscaling)

[4] this downscaling fits differing information from multiple samples into output pixels by averaging, effectively blurring, definitionally making the image less sharp, even if it is more detailed, accurate, or less aliased, this being true for almost every antialiasing method

thanks for the input, but what exactly was your point here?

at a significant computational cos

While we're at it-

RGSS would be nice to have.
