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, DirectSR, NIS, etc.)
• DLSS 5 Neural Rendering — runs alongside Super Resolution rather than replacing it (RTX 50 series only; the DLL is ~158 MB, so expect a longer first download)
• XeSS / XeSS Frame Generation / XeLL
• FSR — Upscaling, Frame Generation, Ray Regeneration, plus an FSR 4 upgrade for games that ship only FSR 3.1 (RDNA 3 / RDNA 4 only; skipped on other GPUs, where FSR 4 cannot run)
• DirectStorage (Windows only)
• Update everything at once, or update individual binaries for a specific game
• Choose what "update everything" means — the caret beside Start Update (and beside the Hub's Update all) opens a menu of technologies. Untick the ones you want left alone and the run skips them; the caret shows a count whenever the run is narrower than everything. The choice applies to that run only and then reverts to your saved preferences, so a one-off "only DLSS this time" never quietly becomes permanent — use Make this my default to write it to Update Preferences instead. Both menus share one scope, so narrowing on the Hub shows up on the Launchers bar and vice versa
• Update a hand-picked set — hover any game card in the Games view to reveal its checkbox, tick the games you want, then hit Update selected. Select all takes every game visible in the current launcher tab, so "update just this launcher" is one click away. The selection carries across launcher tabs and filters, and the run reports one summary rather than a dialog per 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 / Preset D (DLSS 4) / Preset F (DLSS 4.5 Gen 2)
  • 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.
• Proton Upscalers (Linux only) — the Proton Upscalers panel generates per-title Steam launch options (copy-to-clipboard; the same variables work in Heroic/Lutris environment settings):
  • DLSS (NVIDIA) — SR presets (Latest / J / K / L / M) and RR presets (Latest / D / F) plus a Frame Generation override via DXVK-NVAPI, matching the Windows per-game dialog. Works on any Proton, including Valve's.
  • DLL upgrades (GE-Proton / Proton-CachyOS / Proton-EM) — one-toggle PROTON_DLSS_UPGRADE, PROTON_FSR4_UPGRADE (RDNA3/RDNA4 aware) and PROTON_XESS_UPGRADE launch options with optional on-screen indicators. The panel reads each game's Proton build from Steam's compat-tool mapping and disables toggles that build doesn't support.
  • GPU vendor is auto-detected (NVIDIA / AMD / Intel) to show the relevant sections, with RDNA3 mode recommended automatically on RX 7000 GPUs.

• 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
• Card size — the ⋮ menu in the Games header switches the grid between Compact, Comfortable and Large. Compact fits noticeably more of a large library on screen; the choice is remembered between sessions.

• Built-in backup system that snapshots game binaries before modifying them
• Restore any modified DLL from the Backups view
• 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.
