reshade-shaders VS vkBasalt

Here's the nvidia sanctioned list: https://github.com/crosire/reshade-shaders/tree/nvidia/ShadersAndTextures.

LUT.fx is a shader that simply reads the a preprocessor variable for a LUT texture file (found in Textures folder) and then applies the effect of the LUT. However, very importantly, this repo of shaders is installed on EVERY ReShade install unless you skip the Shader installation step entirely. But, if you skip the shader installation step, ReShade doesn't automatically create and link the reshade-shaders and reshade-presets folders in settings for you. So people basically have to download it for convenience sake.

This issue can sometime comes up as - "Failed to download from https://github.com/crosire/reshade-shaders/archive/slim.zip"

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.
