DLSS Updater

What if you could update all the DLSS/XeSS/FSR DLLs for the games detected on your system?

Features

• Cross-Platform Support: Works on both Windows and Linux
• Supports updating games from the following launchers:
  • Steam (including Proton games on Linux)
  • Ubisoft
  • EA Play
  • Xbox Game Pass (PC) - Windows only
  • Epic Games Launcher
  • GOG Galaxy
  • Battle.net (Note for Battle.net: Please ensure that the launcher is open before updating this launcher (this does not apply if you are entering a custom folder))
• Linux Support:
  • Scans Steam Proton prefixes for Windows games
  • Supports Wine prefixes (Lutris, standalone Wine)
  • Automatic Steam path detection on Linux
  • Custom folder support for any game location
  • Enable the DLSS Debug Overlay
• DLSS SR Preset Override:
  • This is currently bugged within the Nvidia driver, not the software, if it doesn't apply, use the Nvidia App for now
  • Configure DLSS Super Resolution presets (K/L/M) with GPU-based recommendations
  • RTX 20/30 → Preset K recommended, RTX 40/50 → Preset M or K
  • Preset L is heavier and may reduce performance
  • Windows: System-wide registry override for all games
  • Linux: Generate Steam launch options with copy-to-clipboard
• A built in backup system for restoring game binaries if needed.
• Support for updating Ray Reconstruction/Frame Generation/Streamline (Reflex Low Latency etc) DLL's.
• Support for updating XeSS/FSR/DirectStorage DLL's (DirectStorage is Windows-only).
• A GUI!
• Support for manual folder locations.
• Backups of updated games to be restored.
• Individual game updates for specific binaries.

The current supported DLL included is DLSS 4.5 (version 3.10.5), and DLSS 4.5 for FG/RR (version 3.10.5). The current supported DLL included is FSR 4 (version 4.0.2.0). The current supported XeSS DLLs include XeSS 2.0.2, XeSS Frame Generation 1.2.2, and XeLL 1.2.1. Please see the Intel XeSS releases for game support details.

Blacklisted Games

The list of games that are not supported (blacklisted) is now maintained in a separate repository as a CSV file. This allows for easier updates and potential future expansion of game-specific information without requiring changes to the main application. You can view the current list of blacklisted games here:

DLSS-Updater-Blacklist

The blacklist includes games that:

• Use their own version of DLSS for testing (e.g., 3DMark)
• Replace the DLL when the game is booted (e.g., Warframe)
• Are using a DLSS version <2.0 (these are non-updatable)
• Have specific compatibility issues with updated DLSS versions

The games that are blacklisted can be disabled manually by clicking the "Manage Blacklist" button in the GUI. This will allow you to skip games for whatever reason.

Restoring modified DLL's

• You can find these in the Backups tab.

Execution Instructions

Windows

Running the Pre-built Application

1. Download the latest release from the Releases page.
2. Extract the downloaded DLSS.Updater.X.Y.Z.zip file.
3. Run the DLSS_Updater.exe executable as an administrator.

Winget

winget install "DLSS Updater"

Chocolatey

Download DLSS Updater from Chocolatey.

Linux

Flatpak (Recommended)

Prerequisites: If you don't have Flatpak installed:

# 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

Install from Flathub:

flatpak install flathub io.github.recol.dlss-updater
flatpak run io.github.recol.dlss-updater

Or download from GitHub Releases:

# 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:

• ~/ (home directory)
• /mnt/ (secondary drives)
• /media/ (mounted drives)
• /run/media/ (removable 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 interface to manage permissions.

Linux Notes

• Steam Proton Games: Auto-detects Proton prefixes 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 to game directories outside the sandbox.
• Windows-Only Features: DLSS Debug Overlay and DirectStorage updates are disabled on Linux (shown as grayed out with tooltips).
• Logs: Application logs are stored at ~/.local/share/dlss-updater/dlss_updater.log.
