DLSSync-Manifest

DLL catalog consumed by DLSSync — an open-source Windows updater that keeps DLSS, FSR, XeSS and DirectStorage DLLs in sync with NVIDIA, AMD, Intel and Microsoft publisher releases.

This repository holds nothing but the catalog data. The application code, manifest builder, and tests live in the DLSSync repository.

What's in here

File	Purpose
manifest.json	Canonical catalog. Generated hourly from upstream sources by CI. Do not hand-edit.
manifest.schema.json	JSON Schema (Draft 2020-12) that the manifest must validate against.
.github/workflows/poll-upstream.yml	Hourly cron that rebuilds manifest.json via the Rust manifest-builder from the DLSSync app repo.
.github/workflows/validate.yml	Schema validation on every push / PR.

Public endpoint

The catalog is served via jsDelivr, which mirrors GitHub raw content over a global CDN with a 12-hour edge cache:

https://cdn.jsdelivr.net/gh/xt0n1-t3ch/DLSSync-Manifest@main/manifest.json

DLSSync consumes this URL by default. Override at runtime via the DLSSYNC_MANIFEST_URL environment variable.

The cdn_url field on every release points to the upstream GitHub release asset or NuGet flat-container URL. This repo does not mirror DLL binaries — DLSSync downloads them directly from the publisher, verifies the SHA-256 against the manifest, and verifies the Authenticode publisher subject at install time.

Schema

The manifest validates against manifest.schema.json (Draft 2020-12). The current schema version is 2. Each release entry carries:

{
  "version": "310.6.0",
  "version_packed": 87169138736103424,
  "filename": "nvngx_dlss.dll",
  "sha256": "<64-hex SHA-256, or 32-hex MD5 for dlss-swapper-sourced entries>",
  "size_bytes": 1234567,
  "signed": true,
  "released_at": "2026-04-15T00:00:00Z",
  "source": "NVIDIA/DLSS@v310.6.0",
  "cdn_url": "https://github.com/.../release/asset.zip",
  "release_notes": "...",
  "signature_subject": "NVIDIA Corporation",
  "channel": "stable",
  "is_dev": false,
  "min_driver": null
}

Why a separate repository

1. The manifest rebuilds on an hourly cron. Keeping it in the app repo would pollute the git log of the application code with hundreds of chore: rebuild manifest commits.
2. jsDelivr caches per commit SHA. Refreshing the catalog should not invalidate the app's CDN entries.
3. The catalog is a public service — other tools (Vortex extensions, CLIs, mod managers) can consume it without depending on the app codebase.

Build locally

The builder lives in the app repo, not here:

git clone https://github.com/xt0n1-t3ch/DLSSync.git
cd DLSSync
cargo run --release -p manifest-builder -- --out manifest.json

Then validate against the schema:

npx --yes ajv-cli@5 validate -s manifest.schema.json -d manifest.json --strict=false --spec=draft2020 --all-errors

License

Apache-2.0 for the catalog metadata, schema and workflows. Each linked DLL retains the EULA of its original publisher (NVIDIA, AMD, Intel, Microsoft). The manifest does not redistribute DLL binaries; it indexes their authoritative upstream locations.
