DLSSync

DLSSync: DLSS, FSR, XeSS, Streamline and driver updater

One place for the whole graphics stack: DLSS, FSR, XeSS, Streamline, DirectStorage, NVIDIA/AMD/Intel GPU drivers and Windows device drivers. Every DLL or installer is hash checked, vendor signed, reversible and zero telemetry.

DLSSync is fully open source. To stay within Nexus Mods policies, the build distributed here is a dedicated Nexus Mods edition with auto-updates removed: nothing in it reaches out to the internet to update itself, so you update it manually from this page, for extra privacy and security. The complete source code remains 100% open source and auditable on GitHub.

What's new in v1.6.9

• Signed catalogs: manifest signatures are enforced before update metadata is trusted.
• Safer driver installs: elevated installer arguments are validated and quoted before launch.
• Vendor only downloads: GPU driver packages are restricted to official NVIDIA, AMD and Intel hosts.
• Cleaner rollback: backup restore is fenced to the game folder, with original DLLs kept ready for one click restore.
• Sharper UI: Library, Catalog, Drivers, Backups, Settings and About now share the minimal dark layout.

• NVIDIA: DLSS Super Resolution, Frame Generation, Ray Reconstruction, Reflex, Streamline sets, driver profile overrides and NVIDIA GPU drivers.
• AMD: FidelityFX Super Resolution, FSR Frame Generation, FSR 4 capable set handling and AMD GPU drivers.
• Intel: XeSS, XeSS Frame Generation, Intel GPU drivers and related runtime packages.
• Microsoft and shared runtimes: DirectStorage, Streamline families and Windows device drivers discovered through Windows Update.

• No guessing: scanned games are matched against a signed manifest with exact hashes and known vendor releases.
• No blind swaps: originals are backed up before replacement and restored from the Backups tab when a game needs rollback.
• No telemetry: DLSSync stores plain JSON and SQLite under your Windows profile. Nothing leaves your PC.
• No vendor lock in: NVIDIA, AMD, Intel and Microsoft stacks live in one catalog.
• No driver hunt: GPU and Windows device driver updates sit next to the game library, with official source checks.

• Library: detects Steam and manual games, groups update ready titles, hides noise and applies selected upgrades in batches.
• Catalog: browses tracked DLSS, FSR, XeSS, Streamline and DirectStorage families with version counts and vendor grouping.
• Drivers: checks detected GPUs against live vendor releases and keeps system component updates visible.
• Backups: stores every replaced DLL first, grouped by game, date, feature and restore state.
• Settings: controls detection, game art, update behavior, language and safety toggles.
• About: shows release notes, manifest state, data paths and project links.

Safety notes

• Anti tamper aware: protected games are flagged before risky swaps.
• Scoped writes: restore and scan logic is fenced so a bad path cannot target the whole drive.
• Driver channel aware: GPU support depends on your hardware and the vendor release channel available for it.
• Backup first: keep backups enabled if you test fresh DLSS, FSR or XeSS builds across many games.
