Linux arm64 (Exec format error):
- The script was downloading the x86_64 DXC release on all Linux hosts;
on aarch64 runners the x86_64 ELF fails with EXEC_FORMAT_ERROR at
shader compilation time. Add uname -m guard: when running on aarch64/
arm64 Linux without a DXC in PATH, exit 0 with an advisory message
rather than downloading an incompatible binary. The FSR3 SDK build
proceeds as it did before the permutation script was introduced
(permutation headers are expected to be pre-built in the SDK checkout).
Windows (bash: command not found, exit 127):
- cmake custom-target COMMANDs run via cmd.exe on Windows even when
cmake is configured from a MSYS2 shell, so bare 'bash' is not resolved.
- Use find_program(BASH_EXECUTABLE bash) at configure time (which runs
under shell: msys2 in CI and thus finds the MSYS2 bash at its native
Windows-absolute path). When bash is found, embed the full path in the
COMMAND; when not found (unusual non-MSYS2 Windows setups), skip the
permutation step and emit a STATUS message.
- AmdFsr3Runtime now probes both the legacy ffxFsr3* API and the newer
generic ffxCreateContext/ffxDispatch API; selects whichever the loaded
runtime library exports (GenericApi takes priority fallback)
- Generic API path implements full upscale + frame-generation context
creation, configure, dispatch, and destroy lifecycle
- dlopen error captured and surfaced in lastError_ on Linux so runtime
initialization failures are actionable
- FSR3 runtime init failure log now includes path kind, error string,
and loaded library path for easier debugging
- tools/generate_ffx_sdk_vk_permutations.sh added: auto-bootstraps
missing VK permutation headers; DXC auto-downloaded on Linux/Windows
MSYS2; macOS reads from PATH (CI installs via brew dxc)
- CMakeLists: add upscalers/include to probe include dirs, invoke
permutation script before SDK build, scope FFX pragma/ODR warning
suppressions to affected TUs, add runtime-copy dependency on wowee
- UI labels updated from "FSR2" → "FSR3" in settings, tuning panel,
performance HUD, and combo boxes
- CI macOS job now installs dxc via Homebrew for permutation codegen
