Find the root folder of the game you wish to mod. Look for the main executable file ( .exe ). Note: Ensure the game relies on the Vulkan API, as this mod will not function on DirectX-only titles.

While portable DLLs are incredibly efficient, custom injection can occasionally cause stability issues. If your game crashes on launch, verify that the game is actually running in Vulkan mode rather than DirectX 11 or 12. Additionally, ensure that your graphics drivers are fully updated to support the latest Vulkan runtimes.

This usually means the game is trying to boot using DirectX instead of Vulkan. Check the game's launch arguments or settings files to force Vulkan mode. Alternatively, the game may have anti-cheat software that blocks external DLL injection.

: This is the key to the keyword's practical use. In this context, "portable" refers to the ability to use this specific FSR2 library without a complex, system-wide installation. It's the heart of "FSR2 injection" mods. Instead of being a fixed part of a game, the DLL can be placed directly into a game's folder. A mod or a tool like OptiScaler can then "trick" the game into loading this portable FSR2 library as if it were a native part of the renderer, often by taking the place of another upscaler's file.
Distributing ffx_fsr2_api_vk_x64.dll from a commercial game (e.g., ripping it from Forza Horizon 5 ) is a legal grey area. However, AMD encourages developer use of FidelityFX via GPUOpen. For portable use on your own machine (personal, non-commercial modding), it’s generally tolerated. Always download from reputable sources—never from shady DLL websites that bundle malware. Note: Ensure the game relies on the Vulkan
