Update every DLSS / XeSS / FSR DLL across all the games on your system — from one place.
Tip
Quick start (Windows): winget install "DLSS Updater" — then launch and hit scan.
Prefer Linux? Grab the Flatpak. Full options are in Installation.

DLSS Updater scans the games installed on your system, detects the upscaling and frame-generation DLLs they ship with, and replaces them with newer versions — with automatic backups so you can always roll back. It runs on Windows and Linux and understands games from every major launcher.
| Runs on Windows & Linux and detects games from every major launcher — Steam, Epic, GOG, Ubisoft, EA, Battle.net & Xbox. | DLSS, Ray Reconstruction, Frame Generation, Streamline, XeSS, FSR & DirectStorage — all at once, or one binary at a time. | Apply global SR / RR / FG preset overrides on Windows, or per-title SR overrides with GPU recommendations on Linux. |
| Optional Steam Web API matching for near-perfect banners, plus custom banner & name overrides that survive rescans. | Every binary is backed up before it's touched — restore any DLL in one click from the Backups tab. | Skip (or force) any title with your own per-game blacklist, layered on top of the community list. |
Cross-platform on Windows and Linux, with detection for the launchers below:
| Launcher | Windows | Linux | Notes |
|---|---|---|---|
| Steam | ✅ | ✅ | Includes Proton games on Linux |
| Epic Games Launcher | ✅ | ✅ | |
| GOG Galaxy | ✅ | ✅ | |
| Ubisoft Connect | ✅ | ✅ | |
| EA Play | ✅ | ✅ | |
| Battle.net | ✅ | ✅ | Keep the launcher open before updating (not required for custom folders) |
| Xbox Game Pass (PC) | ✅ | — | Windows only |
| Custom folders | ✅ | ✅ | Point at any game location manually |
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.
- 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
| Technology | Included version |
|---|---|
| DLSS Super Resolution | 4.5 (3.10.6.0) |
| DLSS FG / RR | 4.5 (3.10.5) |
| FSR | 4 (4.0.2.0) |
| XeSS | 2.0.2 |
| XeSS Frame Generation | 1.3.1 |
| XeLL | 1.3.0.5 |
See the Intel XeSS releases for per-game XeSS support details.
The MSI installer is the recommended way to install on Windows — it installs to Program Files with a proper Add/Remove Programs entry.
Winget (recommended)
winget install "DLSS Updater"Chocolatey — install from the Chocolatey package page.
Direct download — grab DLSS.Updater.X.Y.Z.msi from the Releases page and run it.
The Flatpak is the recommended way to install on Linux.
Install Flatpak (if you don't have it)
# 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.flatpakrepoInstall DLSS Updater
# Download DLSS_Updater-X.Y.Z.flatpak from the Releases page, then:
flatpak install --user DLSS_Updater-X.Y.Z.flatpak
flatpak run io.github.recol.dlss-updaterUninstall
flatpak uninstall io.github.recol.dlss-updaterCustom game directories
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-updaterOr use Flatseal for a graphical permissions manager.
Linux notes
- Steam Proton games: auto-detected at
~/.steam/steam/steamapps/compatdata/. - Wine games: scans
~/.wine/and Lutris games at~/Games/. - Custom paths: use
flatpak overrideor 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.
Prerequisites & build steps
Prerequisites
- Python 3.14 or higher (free-threaded build recommended)
- Git
- uv (Python package installer)
Windows
git clone https://github.com/Recol/DLSS-Updater.git
cd DLSS-Updater
uv sync --frozen
# Build the executable
uv run pyinstaller DLSS_Updater.spec
# …or build the MSI installer
pwsh build_msi.ps1
# Run it
.\dist\DLSS_Updater.exeLinux
git clone https://github.com/Recol/DLSS-Updater.git
cd DLSS-Updater
uv sync --frozen
# Build the executable…
uv run pyinstaller DLSS_Updater_Linux.spec
# …or build the Flatpak
./build_flatpak.sh
# Run it
./dist/DLSS_UpdaterThe list of unsupported (blacklisted) games is maintained as a CSV in a separate repository, so it can be updated independently of the application:
Games are blacklisted when they:
- Use their own version of DLSS for testing (e.g., 3DMark)
- Replace the DLL on launch (e.g., Warframe)
- Ship a DLSS version below 2.0 (non-updatable)
- Have known compatibility issues with updated DLSS versions
You can override the blacklist via the Manage Blacklist button in the GUI to skip (or force) games for any reason.
The tool does not globally block anti-cheat games, since some allow DLL replacement. Individual titles will be blacklisted as they're reported not to function.
Check the Issues section to see if your
problem has already been reported. If not, open a new issue with as much detail as
possible. Each release also ships detailed notes in release_notes.txt and on the
Releases page.
