When ffxCreateContext for the upscaler fails (e.g. on NVIDIA with the
AMD FidelityFX runtime), the shutdown() path called dlclose() on the
runtime library which could hang — the library's global destructors may
block waiting for GPU operations that never completed.
Skip dlclose() on context creation failure: just clean up function
pointers and mark as failed. The library stays loaded (harmless) and
the game continues with FSR2 fallback instead of hanging.
On Windows arm64, wchar_t is unsigned so 'wc >= 0' is always true
and GCC/Clang emit -Wtype-limits. Drop the redundant lower bound
check — only the upper bound 'wc <= 0x7f' is needed.
- 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
