There are ways to apply AMD FSR to almost all Vulkan games in the Linux environment
Recently, AMD fulfilled its open-source promise when it went online and put the source code, development documents, and examples of FidelityFX Super Resolution on the AMD GPUOpen website. Whether game developers or players, the enthusiasm for FidelityFX Super Resolution is relatively high. Recently, more games support FidelityFX Super Resolution, such as “Necromunda: Hired Gun – Hunter’s Bounty Pack” and “Eternal Edge” can support both DLSS and FidelityFX Super Resolution, giving players more choices. Arcadegeddon supports FidelityFX Super Resolution on both PC and PlayStation 5 platforms, allowing everyone to see the broader prospects of FidelityFX Super Resolution on home console platforms.
However, for some old games, game developers may not follow up, but folks are not idle. For example, “Grand Theft Auto V” and “Assetto Corsa” already have MODs that support FidelityFX Super Resolution. However, these technical experts are not satisfied with this. Recently, they have found a way to apply FidelityFX Super Resolution to almost all Vulkan games (including dxvk and vkd3d-proton) in the Linux environment. It has been posted on GitHub. The developer said that although it is not perfect, it is impressive enough by itself.
