# AMD FSR2 Integration Notes
|
|
|
|
WoWee supports two FSR2 backends at runtime:
|
|
|
|
- `AMD FidelityFX SDK` backend (preferred when available).
|
|
- `Internal fallback` backend (used when AMD SDK prerequisites are not met).
|
|
|
|
## SDK Location
|
|
|
|
AMD SDK checkout path:
|
|
|
|
`extern/FidelityFX-FSR2`
|
|
|
|
Detection expects:
|
|
|
|
- `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`
|
|
|
|
## Build Flags
|
|
|
|
- `WOWEE_ENABLE_AMD_FSR2=ON` (default): attempt AMD backend integration.
|
|
- `WOWEE_HAS_AMD_FSR2` compile define:
|
|
- `1` when AMD SDK prerequisites are present.
|
|
- `0` when missing, in which case internal fallback remains active.
|
|
|
|
## Current Status
|
|
|
|
- AMD FSR2 Vulkan dispatch path is integrated and used when available.
|
|
- UI displays active backend in settings (`AMD FidelityFX SDK` or `Internal fallback`).
|
|
- Runtime settings include persisted FSR2 jitter tuning.
|
|
- Startup safety behavior remains enabled:
|
|
- persisted FSR2 is deferred until `IN_WORLD`
|
|
- startup falls back unless `WOWEE_ALLOW_STARTUP_FSR2=1`
|
|
|
|
## FSR Defaults
|
|
|
|
- Quality default: `Native (100%)`
|
|
- UI quality order: `Native`, `Ultra Quality`, `Quality`, `Balanced`
|
|
- Default sharpness: `1.6`
|
|
- Default FSR2 jitter sign: `0.38`
|
|
- Performance preset is intentionally removed.
|
|
|
|
## CI Notes
|
|
|
|
- `build-linux-amd-fsr2` clones AMD's repository and configures with `WOWEE_ENABLE_AMD_FSR2=ON`.
|
|
- Some upstream SDK checkouts do not include generated Vulkan permutation headers.
|
|
- In that case, WoWee CMake intentionally falls back to the internal backend so CI remains buildable.
