This is an interesting open source project! vkBasalt is a new Vulkan post processing layer that currently supports Contrast Adaptive Sharpening.
Unlike Radeon Image Sharpening, vkBasalt supports Linux and works with both NVIDIA and AMD. This isn't entirely reinventing the wheel though, as it's partly based upon the ReShade port of AMD's CAS. Still, it's fun to see what hackers are able to do with little layers like this, especially when we don't have official support.
Want to see the difference it makes? The developer included a comparison shot of Skyrim:
See a bigger comparison on this dedicated page.
Seems like a really fun idea, although the result might not be to everyone's tastes it's very much personal preference. It does make it look quite a lot sharper to my eyes.
It's already seeing plenty of activity on GitHub with others helping out, in time this could be quite an interesting Vulkan layer if more options get added in.
You can find it on GitHub.

Quoting: EhvisI wonder if it's just me, but I really don't like the artificial sharpening. Never have on any medium and for any game that offers the option I turn it off. It just feels harsh and unnatural.
Well, I'm quite amazed how good it looks in the example without adding excessive noise.
Would use it.

It just feels harsh and unnatural.I know what you mean and in general I agree, but in that example (and, as far as I recall, The Witcher 3 with some slight sharpening; not too much), I think it works.
Edit: Heh. It's in the AUR already. Sometimes the Arch community just amazes me.

It just feels harsh and unnatural.I don't get why people use it like that either, but the main selling point of AMD CAS is that it can upscale lower resolutions quite well and provide a decent performance boost in games. Unfortunately this port doesn't work for me, it just crashes in every wine game I try with a page fault error

Quoting: NeoTheFoxGreat job on that sliding preview, it really works well for side-by-side. You are very good at this Liam.Can't take all credit. I implemented it using https://github.com/koenoe/cocoen, no point reinventing the wheel :)

Quoting: 14I like this example and would totally use it in Skyrim at least. I'd test it on many games.I think that's wise. I've quickly tested it on a few; in most, the effect seems more subtle than it appears in that Skyrim shot above: it either just made everything look a bit clearer (the best way I can describe it is that it's as if I'm using higher resolution textures; the road surface in the Skyrim shot is a good demonstration of what I mean), or had so little effect that I'm not even sure if it's working at all. But it definitely gives Elite Dangerous that unpleasant artificial over-sharpened look (maybe it already uses a sharpening filter?).
So, yeah: try it out. Even if you don't like it in one game, you might be surprised by others.
