DLSS-Updater

Cross-platform on Windows and Linux, with detection for the launchers below:

Linux specifics

• Scans Steam Proton prefixes (~/.steam/steam/steamapps/compatdata/)
• Supports Wine prefixes (Lutris, standalone Wine)
• Automatic Steam path detection
• Enable the DLSS Debug Overlay

• DLSS Super Resolution, plus Ray Reconstruction, Frame Generation and Streamline (Reflex Low Latency, etc.)
• XeSS / XeSS Frame Generation / XeLL
• FSR
• DirectStorage (Windows only)
• Update everything at once, or update individual binaries for a specific game

• Global presets (Windows, experimental) — the DLSS Settings card on the home page applies preset overrides to every game via the NVIDIA driver base profile (the same mechanism as the NVIDIA App’s global override). Shows the currently applied preset; takes effect at the next game launch.
  • Super Resolution (SR): Default / Latest / Preset J / K / L / M
  • Ray Reconstruction (RR): Default / Latest model
  • Frame Generation (FG): Default / Latest / Preset A / B
  • ⚠️ Per-game overrides set in the NVIDIA App take priority — set its DLSS override to Default/Off to let this global setting apply.
• Per-game presets (Windows, NVIDIA only) — the DLSS Settings action on any game (right-click a card, or its ⋮ menu) opens a per-game panel that overrides SR / RR / FG for just that title via its NVIDIA per-application driver profile — the same mechanism the NVIDIA App uses for per-game overrides. It takes priority over the global setting for that game and applies at the next launch. The action is hidden automatically on non-NVIDIA systems.
  • The game’s executable is detected automatically (NVIDIA driver lookup → folder heuristic → Steam manifest); when it can’t be determined, a Change executable file picker lets you point at the correct .exe. Your executable and preset choices are remembered between sessions.
  • The panel reads back the value the driver is actually applying and distinguishes NVIDIA’s predefined value from your own override. Reset to default clears the override (reverting to the game’s predefined value) in one click.
• DLSS SR Preset Override (Linux only) — configure SR presets (K/L/M) with GPU-based recommendations, and generate Steam launch options with copy-to-clipboard. Preset L is heavier and may reduce performance.

• Steam Web API integration (optional) — connect your free Steam API key for near-perfect game image matching.
  • Auto-detects your Steam ID from the local installation
  • Four-tier app ID resolution: Manifest → Steam API → Store Search → FTS5 fuzzy match
  • One-click re-resolution to fix images from previous scans
• Custom display — override any game’s banner image and display name via the pencil icon on its card.
  • Search the local Steam app list to find any game (no API key required; credentials improve results)
  • Overrides are stored separately from scanner data, so a rescan can’t revert them
  • Reset to default at any time

• Built-in backup system that snapshots game binaries before modifying them
• Restore any modified DLL from the Backups tab
• Build your own per-game blacklist to skip titles for any reason

# Ubuntu/Debian
sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

# Fedora — pre-installed

# Arch
sudo pacman -S flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

The Flatpak has read-only access to common game locations by default: ~/, /mnt/, /media/, and /run/media/.

To grant access to additional directories:

flatpak override --user --filesystem=/path/to/games io.github.recol.dlss-updater

Or use Flatseal for a graphical permissions manager.

• Steam Proton games: auto-detected at ~/.steam/steam/steamapps/compatdata/.
• Wine games: scans ~/.wine/ and Lutris games at ~/Games/.
• Custom paths: use flatpak override or the in-app dialog to grant access outside the sandbox.
• Windows-only features: DLSS Debug Overlay and DirectStorage updates are disabled on Linux (grayed out with tooltips).
• Logs: stored at ~/.local/share/dlss-updater/dlss_updater.log.
• libmpv issue: if you hit a libmpv error, your distro likely doesn’t bundle the library — see issue #125 for guidance.
