Runtime note:
- Renderer/UI now expose a persisted experimental framegen toggle.
- Runtime loader now probes for AMD FSR3 SDK runtime binaries.
- Runtime loader now supports:
- Path A: AMD SDK runtime binaries (`ffx_fsr3_vk`).
- Path B: wrapper runtime libraries implementing WoWee's wrapper ABI.
- You can point to an explicit runtime binary with:
- `WOWEE_FFX_SDK_RUNTIME_LIB=/absolute/path/to/libffx_fsr3_vk.so` (or `.dll` / `.dylib`).
- Current runtime status is still `dispatch staged` (FI/OF dispatch activation pending).
- You can point to an explicit wrapper binary with:
- `WOWEE_FFX_SDK_RUNTIME_WRAPPER_LIB=/absolute/path/to/libffx_fsr3_vk_wrapper.so` (or `.dll` / `.dylib`).
- Path B wrapper ABI contract is declared in:
- `include/rendering/amd_fsr3_wrapper_abi.h`
- Required wrapper exports:
- `wowee_fsr3_wrapper_get_abi_version`
- `wowee_fsr3_wrapper_initialize`
- `wowee_fsr3_wrapper_dispatch_upscale`
- `wowee_fsr3_wrapper_shutdown`
- Optional wrapper export:
- `wowee_fsr3_wrapper_dispatch_framegen`
