Implement native NGX feature-13 RR through a LUID-matched D3D12/Vulkan
shared-memory and timeline-fence bridge. Add owned parameter snapshots,
GPU resource lifetime handling, inherited/enhanced barriers, optional
guides, sampled input formats and depth-plane support with stencil
preservation. Separate RR initialization from the SR CUDA runtime and
expose explicit backend/model selection through player configuration.
Add synthetic bridge, snapshot and NGX lifecycle harnesses covering
camera/history/reset, parameter mutation, delayed submission, early
release, capability gating and unsupported-input rejection.
Add exact gfx11 D/E model generation, verified caches, versioned local
deployment with configuration backups, and isolated portable model
tools with pinned Python, NumPy and glslang dependencies.
Extend Windows K benchmarking and private native-cache selection.
Fix LLVM 22 emitter/helper compatibility and preserve exact-output
validation for local output-kernel optimization.
Add native FSR RR provider diagnostics, local development package
refresh tooling, installer/checker updates, FidelityFX headers and
Windows parity documentation.
Keep NVIDIA binaries, derived models and private optimized kernels out
of distributable packages. Native RR evidence remains synthetic;
game validation, FSR RR dispatch, installer integration and Linux
performance parity remain incomplete.
Add native K/M/RR inference engines, HIP kernels, replay and validation
harnesses, and Windows DLSS setup and runtime support. Include GPU
profiling tools, build and packaging scripts, platform integration
patches, and implementation documentation.
- Shim: reuse VRAM interop buffers across features instead of freeing them;
ROCm 7.2.x's hipExternalMemoryGetMappedBuffer retains its view twice, so
freed buffers never released their memory (~130 MB per quality change)
- Bridge: close the exported fd after hipImportExternalMemory
- Shim: accept R16G16B16A16_TYPELESS motion vectors and convert 4-channel
motion vectors to RG16F on the GPU, keeping VRAM interop (Dying Light:
The Beast rendered black)
- Harness: D4R_HARNESS_RECREATE=N quality-change cycles,
D4R_HARNESS_MV_RGBA16=1 motion vector format
- Supported games: TLOU, Control, Cyberpunk 2077, Rift Apart, HZD Remastered,
Subnautica 2, Alan Wake 2, Silent Hill 2, Dying Light: The Beast; general notes
