DLSS Updater is a utility designed to automatically update DLSS (Deep Learning Super Sampling), XeSS (Intel Xe Super Sampling), and DirectStorage DLLs for games across multiple platforms.
Key Features:
Supports updating games from popular launchers, including Steam, Ubisoft, EA Play, Xbox Game Pass (PC), Epic Games Launcher, GOG Galaxy, and Battle.net.
Includes a soft backup system for restoring DLLs using DLSS Swapper.
Updates Ray Reconstruction/Frame Generation/Streamline (Reflex Low Latency) DLLs, as well as XeSS/FSR/DirectStorage DLLs.
Features a user-friendly GUI for managing updates and manually specifying folder locations.
Blacklist management to skip games with specific compatibility issues or unsupported DLSS versions.
Audience & Benefit:
Ideal for gamers and tech enthusiasts who want to ensure their games are using the latest performance-enhancing technologies without manual intervention. By automating DLL updates, DLSS Updater helps users achieve better visual quality and performance in supported titles.
The application requires administrative privileges to modify game files and can be installed via winget.
README
DLSS Updater
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.
<h3>🖥️ Cross-Platform</h3>
Runs on <strong>Windows & Linux</strong> and detects games from every major launcher — Steam, Epic, GOG, Ubisoft, EA, Battle.net & Xbox.
<h3>🔄 Updates Everything</h3>
DLSS, Ray Reconstruction, Frame Generation, Streamline, XeSS, FSR & DirectStorage — all at once, or one binary at a time.
<h3>🎛️ DLSS Presets</h3>
Apply global SR / RR / FG preset overrides on Windows, or per-title SR overrides with GPU recommendations on Linux.
<h3>🖼️ Smart Game Images</h3>
Optional Steam Web API matching for near-perfect banners, plus custom banner & name overrides that survive rescans.
<h3>💾 Safe by Default</h3>
Every binary is backed up before it's touched — restore any DLL in one click from the <strong>Backups</strong> tab.
<h3>🚫 Custom Blacklist</h3>
Skip (or force) any title with your own per-game blacklist, layered on top of the community list.

Update everything at once, or update individual binaries for a specific game
🎛️ DLSS Preset Configuration
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.
🖼️ Game Images & Custom Display
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
💾 Backups & Safety
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
# 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-updater
Uninstall
flatpak uninstall io.github.recol.dlss-updater
Custom game directories
The Flatpak has read-only access to common game locations by default: ~/, /mnt/,
/media/, and /run/media/.
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.exe
Linux
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_Updater
Blacklisted Games
The list of unsupported (blacklisted) games is maintained as a CSV in a separate
repository, so it can be updated independently of the application:
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.
Anti-Cheat
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.
Troubleshooting
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.
