Padded DLSS input fix — v0.6.1

Complete OptiScaler package built from runtime commit bab959eb. Packaging documentation is updated
for this release. Promoted from preview without changing the binaries. The NR integration remains
experimental; this is not a verified Dawnwalker-specific fix.

What changed

• NR can stay before DLSS Super Resolution when an origin-zero active image is smaller than its
  colour texture allocation. For example, 2558x1439 inside 2560x1440 no longer automatically sends
  NR to the post-upscale 4K path. This is not a whitelist of specific resolutions.
• Only the active image is copied in/out; padding is preserved. This also handles game colour
  textures without UAV support. Model resolution still follows the active size and WorkingScale.
• Includes the earlier per-pass controls, optional skin/environment controls, external FG-owner
  mode and candidate Onimusha state-restoration fix. See the included compatibility documents.
• Includes the pinned Streamline/FG downloader, official sources and installation instructions.
  No NVIDIA NR or FG runtime DLLs, or RTX 40 unlocker binaries, are bundled.

Update an existing installation

1. Close the game and launcher. Back up the current OptiScaler files and INI.
2. Extract the entire ZIP into a temporary folder first. Follow INSTALL-DLSSNR.md to update the
   installed files while preserving your configuration, separately supplied NR runtime and other mods.
3. Replace the DLL the game actually loads. If OptiScaler was installed as dxgi.dll, for example,
   use this package's OptiScaler.dll to replace that OptiScaler-owned proxy. Merely adding an unused
   OptiScaler.dll beside an old proxy will not update the running mod. Do not overwrite a proxy
   owned by ReShade, another mod or the game.
4. Keep the package's backend directories and forwarder together. New features remain off by default;
   preserve/merge existing INI settings rather than blindly replacing a working configuration.
5. Enable Apply before Super Resolution, start with one NR pass and 100% model resolution, with
   FG/RR off. Switch DLSS modes and inspect OptiScaler.log for the active/target/model dimensions.

Non-zero colour offsets and invalid layouts still fall back after SR. RR still uses the separate
post-RR path. Frequent dynamic-resolution changes can cause model rebuilding overhead.

Checks and limits

Release x64 DLL and forwarder built successfully. Headless D3D12 WARP tests verified every copied
pixel and preserved padding for 2558x1439, 2227x1253 and exact 1920x1080 inputs, including no-UAV and
simulated failure cases. Existing skin shader tests passed. The system D3D12 debug layer was unavailable.
Existing compiler/linker warnings remain. Dawnwalker, 1507x847 model evaluation and NVIDIA's acceptance
of these exact odd-sized model inputs still require in-game confirmation.

The release includes SHA256SUMS.txt for its contents. ASSET-SHA256SUMS.txt beside the download
contains the ZIP checksum. Verify your download and keep antivirus enabled.
