AMD FSR2 Vulkan Permutation Snapshot

This directory contains pre-generated Vulkan permutation headers used by the AMD FSR2 SDK Vulkan backend.

Why this exists:

  • Recent upstream GPUOpen-Effects/FidelityFX-FSR2 checkouts may not include generated *_permutations.h files.
  • WoWee uses these vendored headers to bootstrap AMD FSR2 builds consistently on Linux, macOS, and Windows without requiring Wine.

Source SDK commit used for this snapshot:

  • 1680d1e (from local extern/FidelityFX-FSR2 checkout when snapshot was generated)

Refresh process:

  1. Regenerate Vulkan permutation headers in extern/FidelityFX-FSR2/src/ffx-fsr2-api/vk/shaders.
  2. Copy ffx_fsr2_*pass*.h files into this directory.
  3. Commit the updated snapshot together with any AMD FSR2 integration changes.
