vkBasalt VS SweetFX

there is vkbasalt for image sharpening. i don't know if it'll provide the image you want, but you can configure it and see if it fits your needs.

There is a alternative for Linux called vkBasalt. I haven't used it myself, yet, so I don't know how well it works. Your distro may have a package for it.

In the meantime, you can Generate a LUT yourself and apply it to games using ReShade or vkBasalt, but it doesn't apply to the system as a whole, takes a bit of work to use with each game, and there are certain games that won't work with it at all (rendering OpenGL games through Zink might help, but there are still gaps in its coverage afaik). All that effort is not for the faint of heart, lol.

The solution: vkBasalt

In the ticket there is also someone suggesting vkBasalt as a replacement.

The easiest way to do this on linux is to use vkbasalt with goverlay.

Download all the shaders/textures from the ReShade and SweetFX repositories. Merge them, you should have a single Shaders folder with all shaders and a single Textures folder with all textures.

I've tested the sharpening filters quite a lot in the past few weeks, the Filmic Anamorphic Sharpen to my eyes is too sharp, it seems to add some kind of whiteness around objects, CAS is fine, but it doesn't sharpen much with default settings, DELC seems to be the best with its default settings.
