The Vulkan backend for FSR 2 requires explicit mapping of Vulkan handles and procedure addresses. In practice, developers using Rust bindings would interact with FSR 2 through crates that provide safe abstractions, but under the hood, the Vulkan backend expects dynamic linking of Vulkan functions.
When a game initiates an upscaling request through a Vulkan interface, it hands over local render targets (such as depth, motion vectors, and color buffers) to this backend library. The backend translates these items into Vulkan-readable compute shaders. Step-by-Step Installation & Placement ffx fsr2 api vk x64dll work
