OptiScaler DLSS-NR is an independently licensed project, not part of this application's MIT-licensed implementation: https://github.com/Dagherbou/OptiScaler_DLSSNR
A second, independently licensed project is offered per game: the pre-SR multipass fork of the same idea, pinned at the DLSS5-Feeder author's build of it. Everything below applies to both. https://github.com/wilsjo2/OptiScaler-DLSSNR-PreSR-Multipass https://github.com/jlrouzies-fr/OptiScaler-DLSSNR-PreSR-Multipass
The optional backend downloads the official archive of the build a game names directly from its release page, with a pinned SHA-256 checksum. No upstream executable, DLL or source is bundled with Swapper, and its setup/removal scripts are not executed. Upstream binaries remain unmodified; configuration and tracked deployment are performed by this application.
The upstream GNU GPL version 3 licence (commit 393e070) is downloaded and
checksum-verified separately because it is not included in Dagherbou's release
ZIP; the pre-SR fork carries its own copy inside the archive the pinned digest
already covers, and the fork's PeripheralWarp and FidelityFX v1 notices travel
with it.
The licence, RenoDX attribution, and supplied DirectX/FidelityFX/XeSS notices
are retained in the cache and copied into OptiScaler/licenses in the game.
Corresponding upstream source: https://github.com/Dagherbou/OptiScaler_DLSSNR/tree/393e070
Corresponding upstream source for the fork:
https://github.com/jlrouzies-fr/OptiScaler-DLSSNR-PreSR-Multipass/tree/v0.8.92
NVIDIA's Neural Rendering runtime is not supplied by this OptiScaler release.
This integration uses the existing Swapper payload's nvngx_dlssnr.dll; it
does not relicense that file or imply NVIDIA support for the integration.
The bundled client add-ons, 64-bit helper, shader and diagnostic verifier are from the official DLSS5-Feeder v1.17.0 release: https://github.com/jlrouzies-fr/DLSS5-Feeder/releases/tag/v1.17.0
The project's MIT licence is included in payload/feeder/licenses/DLSS5-Feeder-LICENSE.txt. Release archive and component checksums are pinned in src/core/feeder-release.js.
Two builds of ShortFuse's RenoDX neural consumer are bundled: the generic DLSS 5 add-on that every route installs, and the DLSS Tool build that the multipass route installs in its place. https://github.com/clshortfuse/renodx
Both are redistributed from the community release repository the upstream Feeder installer also draws on, and each is pinned by release URL and digest in src/core/renodx-release.js: https://github.com/RankFTW/rhi-repo/releases
dgVoodoo2 is a separately licensed runtime dependency for DX8/DX9 translation: https://github.com/dege-diosg/dgVoodoo2 https://dege.freeweb.hu/dgVoodoo2/ReadmeGeneral/
Its binaries are not bundled with this application. When a DX8/DX9 installation is requested, the application downloads the complete official v2.87.5 archive, verifies its pinned SHA-256 checksum and retains the original documentation and licence in its component cache. dgVoodoo2 remains under its author's licence, not this application's MIT licence.
The emulator profile table and parts of the Vulkan/Feeder installation model were adapted from DLSS5-Autopilot: https://github.com/Kizzuwatnaa/DLSS5-Autopilot
