The pinned upstream notice identifies vitruvian_head.glb and the
vit_*.png character textures as CC0 assets derived from the "Vitruvian"
base of the CharMorph Blender add-on. It credits Vitruvian to Sean Buckley and
Olaf Delgado-Friedrichs, relicensed from "Antonia Polygon," with contributions
credited in the CharMorph data. No attribution is legally required under CC0;
this notice preserves the upstream provenance as a voluntary credit and does
not imply endorsement.
Only the head GLB and six texture files listed above are included. No
VitruvianGodot code or shaders, vitruvian_body.glb, source .blend files,
Mixamo source clips, or Mixamo-derived body animations are included. Upstream
describes its Mixamo animations as subject to Adobe's license; they are not
part of this CC0 asset import and must not be treated as CC0.
The public DLSS5-Feeder implementation was inspected to understand the ordinary same-device documented NGX feeder contract. ChromiumRTX does not compile, link, redistribute, or copy that project. It independently implements a controlled WebGPU resource-registration and NGX DLAA path.
The separate renodx-dlss5.addon64 used by the packaged reference setup is not
part of the public feeder source, is not linked or staged by ChromiumRTX, and is
not covered by the following MIT notice.

When CHROMIUMRTX_ENABLE_NGX=ON and a valid
CHROMIUMRTX_NGX_SDK_ROOT is supplied, ChromiumRTX includes NVIDIA's public
NGX headers and links its Windows x64 NGX import library. The SDK is not fetched
or stored by this repository.
When a user supplies CHROMIUMRTX_NGX_RUNTIME_DIR, the local build may copy
that directory's nvngx_dlss.dll beside the experimental executable. The
file remains user-supplied. No NVIDIA runtime is part of the ChromiumRTX source
distribution.
ChromiumRTX also contains an experimental manual Streamline adapter for private
feature 1004 / NGX feature 18. When CHROMIUMRTX_ENABLE_DLSS_NR=ON and a valid
external CHROMIUMRTX_STREAMLINE_SDK_ROOT is supplied, the build compiles
against that root's Streamline headers and stages these four user-supplied files
from its bin/x64 directory beside the local test executable:
sl.interposer.dllsl.common.dllsl.dlss_nr.dllnvngx_dlssnr.dll
The single locally exercised package identifies its public header ABI as
Streamline 2.12.0 while the signed binaries identify themselves as
2.13.0.0. ChromiumRTX uses the supplied header's sl::kSDKVersion; this
notice does not claim that those independently numbered artifacts are
interchangeable with another Streamline distribution.
The repository does not fetch, embed, or store those files. They must not be committed, attached to issues, or redistributed in ChromiumRTX source or binary releases without separate permission from NVIDIA and compliance with the applicable NVIDIA terms. Each developer is responsible for lawfully obtaining the SDK/runtime and reviewing its complete license. This notice is not a grant of rights to any NVIDIA material.
Before loading the feature-1004 path, ChromiumRTX requires all four files and
uses Windows WinVerifyTrust to validate each embedded signature. The check is
cache-only, performs no online revocation lookup, and does not create
redistribution rights. Missing or signature-invalid files fail closed to the
ordinary provider/fallback path.
To expose NGX feature 18 to that signed runtime, ChromiumRTX temporarily changes
a feature-name pointer only in the current WebView2 GPU process. It first
requires an exact match for the known preceding feature-name table and the
empty feature-18 slot, restores the original pointer after slShutdown and on
failure, and never patches _nvngx.dll on disk. This guarded mapping and the
feature-1004 options/tag contract rely on unpublished, private NVIDIA ABI. They
may break with any NVIDIA driver, Streamline, or DLSSNR update and are not an
officially supported integration surface.
The closed renodx-dlss5.addon64 is still not included, linked, staged, or
loaded. ChromiumRTX's feature-1004 adapter is an independent experiment and
does not confer any right to use or redistribute RenoDX or ReShade components.
If ${CHROMIUMRTX_NGX_SDK_ROOT}/license.txt exists, the build copies the full
NVIDIA RTX SDKs License to the output as nvsdk_ngx.license.txt. That staged
file is the authoritative license for the SDK and associated NVIDIA materials.
Among other requirements, the license restricts the SDK to compatible NVIDIA
GPU systems and imposes distribution and attribution conditions. Review and
accept the complete license before enabling or distributing an NGX build.
ChromiumRTX's bounded feature-1004 option structure, resource-tag sequence, Streamline lifecycle adapter, and guarded process-local NGX feature-name mapping were adapted from the repository owner's existing ThreeBrowser work in the MIT-licensed threepp codebase, then integrated with ChromiumRTX's distinct D3D12 provider, command slots, fences, and browser protocol. No ThreeBrowser binary or NVIDIA payload is included by this attribution.
