# Native Windows RDNA4 game development package
|
|
|
|
Validated hardware: Windows 11 x64 / Radeon RX 9070 XT / gfx1201. Native K and
|
|
M transformer kernels pass standalone D3D12 + OptiScaler checks. Silent Hill 2
|
|
K now renders real menu frames and M renders a saved gameplay level with
|
|
GPU NaN/Inf checks. Resolution coverage and performance are still being
|
|
validated. This is a local
|
|
development package; no NVIDIA proprietary DLL is included.
|
|
|
|
Build the shim/diagnostics, corrected ZLUDA, K/M native objects and patched
|
|
OptiScaler using the scripts in `scripts/windows`, then run:
|
|
|
|
```powershell
|
|
.\scripts\windows\package-windows-game.ps1
|
|
```
|
|
|
|
The package pins TheRock 10.2.0a20260929 because its Windows external-memory
|
|
mapping lifetime passes the repeated import/release test. Stable HIP 7.2 has
|
|
a reproduced mapped-view leak; see `docs/windows-rdna4-port.md` for the source
|
|
fix, exact dependency versions, validation and complete build commands.
|
|
|
|
Run a D3D12 game without anti-cheat using your locally supplied NVIDIA DLLs:
|
|
|
|
```powershell
|
|
.\dist\windows-rdna4-game\windows-game.ps1 -GameExe "D:\Games\SILENT HILL 2\SHProto\Binaries\Win64\SHProto-Win64-Shipping.exe" -NgxCore "C:\Users\Administrator\d4r\_nvngx.dll" -DlssDll "C:\Users\Administrator\d4r\nvngx_dlss.dll" -Preset 11
|
|
```
|
|
|
|
Use `-Preset 13` for M. The validated manifest requires DLSS 310.9.1 with the
|
|
recorded SHA256; other feature DLLs require regenerating and validating the
|
|
native manifest. Select an upscaler supported by OptiScaler in the game.
|
|
The script installs `dxgi.dll`, an explicit DLSS configuration and a private
|
|
`d4r` runtime directory, and captures stdout/stderr, an external debugger log,
|
|
crash dump, loaded DLL paths, driver information and OptiScaler logs. A local
|
|
ZIP bundle is printed at exit. `-RunSeconds 120` bounds a diagnostic run;
|
|
the normal default allows you to play until you close the game.
|
|
|
|
For the Silent Hill 2 startup black-screen investigation, add
|
|
`-DiagnosticResolution 1280x720`. This backs up its two graphics configuration
|
|
files, temporarily selects a window at that resolution, and restores the
|
|
original bytes after the test. It does not change progression saves. First-use
|
|
PTX compilation can be slow; `-CacheDirectory <existing-ZLUDA-cache>` reuses
|
|
modules with matching GPU, codegen switches and ZLUDA binary fingerprint.
|
|
|
|
Add `-ValidateOutput` to scan the entire RGBA16F DLSS output for NaN/Inf on
|
|
the GPU before returning it to D3D12. Only two diagnostic counters (8 bytes)
|
|
are read by the CPU; image data remains in VRAM. Validation failures are
|
|
reported explicitly. Disable this diagnostic when measuring production speed.
|
|
|
|
Original files are backed up before replacement. Restore with:
|
|
|
|
```powershell
|
|
.\dist\windows-rdna4-game\windows-game.ps1 -Action restore -GameExe "D:\Games\SILENT HILL 2\SHProto\Binaries\Win64\SHProto-Win64-Shipping.exe"
|
|
```
|
|
|
|
Restore refuses to overwrite files changed since installation. Backups and
|
|
diagnostic results are retained. The script does not change progression saves,
|
|
system DLLs, driver settings or security settings. All runtime work is native
|
|
Windows. Colour, depth, motion, exposure and output cross APIs through VRAM
|
|
and shared D3D12 fences; the backend waits for the current frame and never
|
|
uses a previous-frame fallback.
|

OptiScaler source modifications are GPL-3.0 and exported under
|
