Thanks to the modding community, MD FideliltyFX Super Resolution If you are willing to follow some steps and implement them manually, you can now use it in SteamVR and Vulkan compatible games. Due to the open source nature of FSR, this allows gamers to effectively build FSR “patches” for SteamVR and Vulkan.
A modified version of Vulkan by Georg Lehmann (@DadSchoorse); By installing FSR into FSHack, you can work in the dxvk shader and Steam’s Proton layer-this technology allows to reduce the resolution in the game without changing the original resolution of the display.
This mod will allow you to use FSR in almost all games supported by Vulkan and provide you with more control than AMD’s normal FSR. You can choose any resolution you want to increase, and choose the sharpness value according to your preference. 0 is the maximum sharpness, the higher the number, the lower the game sharpness.
But there are a few caveats that may make adding FSR a headache, some of which include auto-upconverters that cannot be used with FSR at all, and the patch set itself may be a headache to install.

SteamVR implementation, built by Frydrych Holger (@fholger), it is easier to use. All you need to do is to download the modified .dll file and install it directly into the game’s file directory.
The FSR implementation here is the same as Vulkan, allowing you to specifically change the resolution and change the definition at will.

The mod community showed us how powerful the open source features of FSR are, allowing you to easily add FSR to any game you want. This is expected to further accelerate the adoption rate of FSR and provide some additional competition for DLSS.
