- Source URL:
- `https://github.com/GPUOpen-Effects/FidelityFX-FSR2.git`
- Ref:
- `master` (depth-1 clone)
- The renderer enables the AMD backend only when both are present:
- `extern/FidelityFX-FSR2/src/ffx-fsr2-api/ffx_fsr2.h`
- `extern/FidelityFX-FSR2/src/ffx-fsr2-api/vk/shaders/ffx_fsr2_accumulate_pass_permutations.h`
- If the SDK checkout is missing generated Vulkan permutation headers, CMake auto-bootstraps them from `third_party/fsr2_vk_permutations`.
- If SDK files are missing entirely, CMake falls back to the internal non-AMD FSR2 path automatically.
### FidelityFX SDK (Framegen Extern)
- Build scripts and CI also fetch:
- `extern/FidelityFX-SDK`
- Source URL:
- `https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK.git`
- Ref:
- `v1.1.4` (depth-1 clone)
- This ref includes Vulkan framegen building blocks (`frameinterpolation` + `opticalflow`) and Vulkan shader manifests:
- `sdk/src/backends/vk/CMakeShadersFrameinterpolation.txt`
- `sdk/src/backends/vk/CMakeShadersOpticalflow.txt`
- CMake option:
- `WOWEE_ENABLE_AMD_FSR3_FRAMEGEN=ON` enables a compile-probe target (`wowee_fsr3_framegen_amd_vk_probe`) that validates SDK FI/OF/FSR3/Vulkan interface headers at build time.
### Current FSR Defaults
- Upscaling quality default: `Native (100%)`

- GitHub Actions builds on every push: Linux (x86-64, ARM64), Windows (x86-64, ARM64 via MSYS2), macOS (ARM64)
- All build jobs are AMD-FSR2-only (`WOWEE_ENABLE_AMD_FSR2=ON`) and explicitly build `wowee_fsr2_amd_vk`
- Each job clones AMD's FSR2 SDK; if generated Vulkan permutation headers are absent upstream, WoWee bootstraps them from `third_party/fsr2_vk_permutations`
- Each job clones AMD's FSR2 SDK and FidelityFX-SDK (`v1.1.4`)
- Linux CI asserts FidelityFX-SDK Vulkan framegen files are present (FI/OF GLSL callbacks + Vulkan shader manifests)
- All CI platform jobs explicitly build `wowee_fsr3_framegen_amd_vk_probe`
- If FSR2 generated Vulkan permutation headers are absent upstream, WoWee bootstraps them from `third_party/fsr2_vk_permutations`
- Container build via `container/build-in-container.sh` (Podman)
