    Phoronix: Open-Source C.A.S. Vulkan Layer - Similar to Radeon Image Sharpening But For Any GPU

    AMD's Radeon Image Sharpening feature is designed to improve image quality with minimal performance costs. However, it is only supported by Radeon Polaris / Vega / Navi graphics cards and only under Microsoft Windows 10. An independent open-source project has implemented contrast adaptive sharpening support for Vulkan that is similar to Radeon Image Sharpening but will work for any Vulkan-enabled GPU -- including NVIDIA GPUs...

    Hmm, I wonder if this works as a Vulkan layer when playing a DX11 game DXVK? It would be rather humorous if Linux supported driver level sharpening using AMD's algorithm before AMD supported RIS in native DX11 on Windows.

      Wait, can this just be enabled on any vulkan game?

        Yes it does, and why wouldn't it? The restrictions AMD put on RIS are totally arbitrary...

          HardwareUnboxed looked into this and no, they did not put arbitrary restrictions on it. The performance hit is immesurable (like 0.1 fps hit) and is significantly better in performance to both Nvidia's implementation as well as a CAS reshade version. There is actual work that went into optimizing the code.

            I rather liked CAS with reshade.me, so this will be nice indeed. Linux needs a project like Reshade.me really.

              Just for interest I've just tried a dx9 game on Windows 10 using d9vk and RIS enabled on my RX 580 and the sharpening worked. So it doesn't matter if you're using it with a native vulkan game or with dxvk/d9vk.

                It does work with DXVK.

                In fact , you can use DXVK on Windows to use RIS itself. It works too.

                  It works now for Nvidia GPUs only. It crashes with AMD GPUs.

                    No, I think this issue is fixed. This testing release fixed the issue with my AMD GPU >> https://github.com/DadSchoorse/vkBas...kBasalt.tar.gz
