FidelityFX Super Resolution 2.2 (FSR 2.2)

AMD FidelityFX Super Resolution 2 (FSR 2) is an open source, high-quality solution for producing high resolution frames from lower resolution inputs.

This crate provides unsafe, 1:1 Rust bindings for the FSR2 library. For documentation on how to use the library, please refer to https://github.com/GPUOpen-Effects/FidelityFX-FSR2.

The crate uses a custom fork of FSR2 with minimal changes:

• Removed dependency on cauldron-media to avoid downloading unused sample assets
• Does not build sample backends by default
• Vulkan backend does not link to Vulkan at all, instead relies on provided function pointers on initialization.

Known issues

• Bindings for the DirectX12 backend are currently missing.
• Computer can freeze for a couple seconds during build. This is due to FSR2 generating shader permutations using a bunch of threads.
