Warning
OptiTux GUI is an independent, community-built tool and has no affiliation with the official OptiScaler project. OptiScaler is developed and maintained by its own team. This tool simply provides a graphical interface to manage OptiScaler installations on Linux. All credit for OptiScaler itself goes to its developers — see Credits.
OptiTux GUI lets you install, configure, and remove OptiScaler across your Linux game library — without touching the terminal or manually copying files.
It scans your Steam and Heroic library, detects your GPU, picks the right upscaling backend automatically, and handles everything from downloading OptiScaler releases to writing the correct configuration into OptiScaler.ini.
What you can do with it:
- Browse your installed games and see which ones have OptiScaler active
- Quick Install — one click, done. Detects your GPU, picks the best upscaler, downloads if needed, installs and configures
- Custom Install — choose the exact OptiScaler version, upscaler backend (FSR, DLSS, XeSS), whether to include the FSR4 INT8 addon, and optionally enable Frame Generation
- Download and manage OptiScaler releases from both the official repository and the OptiTuxDB
- Uninstall cleanly, with automatic backup and restore of the original DLLs
OptiTux GUI is built with Tauri and runs on Linux.
Runtime dependencies (required):
- A working desktop environment with WebView support (WebKitGTK)
Optional but recommended:
OptiScaler releases ship as .7z archives. OptiTux GUI includes a fallback extractor, but the native p7zip binary is significantly faster — especially noticeable on large archives.
| Distro | Command |
|---|---|
| Arch / Manjaro | sudo pacman -S p7zip |
| Fedora / RHEL | sudo dnf install p7zip p7zip-plugins |
| Ubuntu / Debian | sudo apt install p7zip-full |
| openSUSE | sudo zypper install p7zip |
Used to accurately detect your GPU model and architecture. Without it, GPU detection falls back to sysfs, which may be less precise for certain cards.
| Distro | Command |
|---|---|
| Arch / Manjaro | sudo pacman -S pciutils |
| Fedora / RHEL | sudo dnf install pciutils |
| Ubuntu / Debian | sudo apt install pciutils |
| openSUSE | sudo zypper install pciutils |
All installation files can be found on the GitHub Releases page. Choose the format that best fits your Linux distribution.
Ideal for Debian and Ubuntu-based distributions.
- How to install:
- Download the
.debfile. - Double-click the file to open it with your interface's package installer (such as GNOME Software or GDebi Package Installer).
- Alternatively, install via terminal:
sudo apt install ./optitux-gui_amd64.deb
- Download the
Ideal for distributions that use the RPM package manager.
- How to install:
- Download the
.rpmfile. - Double-click the file to open it with the Software Center (GNOME Software, Discover).
- Alternatively, install via terminal:
sudo dnf install ./optitux-gui.rpm

Flatpak is a universal format that runs in a sandbox, ensuring the program works regardless of the libraries installed on your main system.
- Requirements: You must have Flatpak support enabled on your distro. If you don't have it, follow the instructions at flatpak.org/setup.
- How to install:
- Download the
.flatpakfile. - Since this is a local package (bundle), it should be installed via terminal to ensure that permissions and runtime dependencies are correctly pulled:
flatpak install ./optitux-gui.flatpak
- Follow the on-screen instructions and confirm the installation of dependencies (GNOME runtimes) if prompted.
- Download the
- How to run: The app will appear in your system menu.
⚠️ Troubleshooting (Missing Icon): On some distributions (especially Arch-based like CachyOS, Manjaro, or EndeavourOS), the app icon might not appear immediately after installation. To fix this:- Restart your session: Log out and log back in, or simply reboot your system. This forces the desktop environment to refresh the Flatpak export paths.
- Manual Run: You can always launch it via terminal while the icon doesn't show:
flatpak run optitux-gui
This is a compressed file containing the program's binary. It can be run on any Linux distribution as long as the system has the base libraries installed.
- Requirements: Make sure you have the runtime dependencies listed in the Requirements section (such as
webkit2gtk,p7zip, andpciutils). - How to install:
- Download and extract the file:
tar -xzf optitux-gui.pkg.tar.zst
- Enter the extracted folder:
cd optitux-gui - Give execution permission to the binary (if necessary):
chmod +x optitux
- Run the program:
./optitux
- Download and extract the file:
- Tip: You can move the extracted folder to a permanent location (like
/optor~/.local/bin) and manually create a.desktopfile so it appears in your menu.
You will need Rust and Node.js installed.
# Clone the repository

npm run tauri dev
# Build a release binary
npm run tauri buildRunning a community hub with version hosting and infrastructure costs time and money. If OptiTux GUI has been useful to you, consider supporting its development:
OptiTux GUI would not exist without the work of the OptiScaler project.
OptiScaler — the upscaling compatibility layer that OptiTux GUI manages. All upscaling functionality, DLL injection, and INI configuration logic belongs to the OptiScaler team and its contributors.
If you find OptiScaler useful, consider supporting its developers directly through their repository.
