Players extract one ZIP into the game folder, copy their two NVIDIA
DLLs, and start the game from Steam, Epic or a shortcut. No launcher
script is needed; settings live in d4r\d4r.ini.
- Shim player mode: when the launcher has not set D4R_HIP_ROOT and
d4r.ini sits beside the shim, derive the backend environment from it.
Codegen flags stay at the Windows-validated values. NVIDIA DLLs must
match an exact SHA256 in dll-pins.txt, with "you have X, you need Y"
errors. Rejects a vkd3d/Wine d3d12.dll and code objects built for
another GPU. [DLSS] Model accepts K or M and is applied by rewriting
the render preset hints.
- d4r.ini exposes only options that exist on Windows: Model, AsyncInterop,
ValidateOutput, Log, CacheDir. Invalid values fall back with a note in
d4r_nvngx.log.
- d4r_nvngx_loader: one _nvngx.dll for all GPUs. It matches the game's
adapter by LUID and loads _nvngx_<arch>.dll from the same folder.
- OptiScaler patch 0006: relative NvngxPath/NvngxDlssPath/
NvngxFeaturePath resolve against OptiScaler's folder.
- package-windows-release.ps1 builds the release from the per-target
game packages and refuses mixed targets or differing shared runtimes.
- Tests: test-player-config.ps1 (ini and DLL-pin decisions, loader
selection on the local GPU) and test-windows-release-package.ps1.
Adapt official LLVM 7a0829e41228 to the pinned LLVM 22 parser and ELF structures. Apply and audit the complete source delta before building, export its provenance, and package the source patch. Add 33 offline public PTX compilation checks across all eleven GPU targets without hardware execution. Preserve strict arithmetic and document RX9070XT K/M regressions.
Share explicit target metadata across build/runtime/package guards, preserve native gfx11 WMMA with a Windows LDS lane exchange, select HIP devices by D3D12 LUID, and reject wrong-target/vkd3d installations before changing game files. Review all issue #10 logs and document compile-only coverage plus RX9070XT regressions.

Add explicit gfx1200/gfx1201 builds, runtime selection and per-target
code objects. Guard staging, packaging and installation against mixed
architectures; retain gfx1201 compatibility and strict K/M arithmetic.
Adapt realdody's target configuration and MSVC binary16/BOOL portability
fixes from ae530b0. Do not import its forced gfx12 layout on RDNA3.
Add exhaustive binary16 and C++/PowerShell target contract regressions.
Validation: 20 CTest gates on RX 9070 XT; four software-only gfx1200 gates;
MSVC portability compile checks; exact 4K K async and M control outputs;
isolated package install/restore and mixed-target rejection tests.
No physical gfx1200 validation is claimed.

- Add default-off PreferAccuracy for all native kernel families,
including RDNA4 FP8 variants.
- Restore intermediate FP8 quantization, per-MMA FP16 rounding,
denormal handling and NGX synchronization in accuracy mode.
- Select separately marked accuracy kernels and use a separate JIT
cache; reject mixed sets and never silently substitute fast kernels.
- Add a pinned GLIBC 2.41 build environment for ZLUDA/LLVM, the DLLs
and both kernel sets, with ABI checks and toolchain provenance.
- Support parallel target builds and pre-extracted PTX; correct
ROCm header paths and Clang-CL input handling.
- Bump to 0.1.3 and update release notes, documentation and tests.
Validation: 11 tests passed; all 912 kernels built; E/K/M GPU harness
runs completed with accuracy off/on. Packaged libraries loaded under
GLIBC 2.41 and require no GLIBC version newer than 2.38.
RTX image-quality parity remains unverified.

- Fix Cyberpunk 2077 preset-K black artifacts by preserving FP16/FP64
denormal requirements while limiting denormal suppression to FP32.
- Fix stale direct-output redirects after array destruction, preventing
reused handles from inheriting an earlier feature's output buffer.
- Log rejected resource formats and dimensions, including failures after
startup, with rate limiting for repeated errors.
- Add opt-in blocking output synchronization with a dedicated bridge
export and fallback to context synchronization.
- Report output-wait CPU and wall time, and defer GPU timing queries
until asynchronous evaluation has completed. The CPU-overhead
mitigation for #7 still needs reporter confirmation.
- Reject release libraries requiring GLIBC newer than the configured
baseline, defaulting to 2.41, and document compatible builds.
Validation: shim and bridge builds pass; targeted redirect-lifetime and
format-logging checks pass.
