I started GameOpti for my own Linux gaming setup. I wanted one place to manage my games, their launch settings and the tools I use with them. The project has grown since then, but that is still the main idea: keep settings per game and make it easier to see what a change actually does.
GameOpti 2.2.0 Beta is available from GitHub Releases. The project is still in active development, so compatibility depends on the game, launcher, hardware, drivers and installed components. Screenshots below show the current interface; some views use sample data.
Report problems through GitHub Issues. Project updates and demonstrations are on YouTube.
GameOpti has its own per-game launch handling, performance analysis, Deep Compression and resource-management features. It also manages several external graphics and monitoring tools. Those tools keep their own requirements and compatibility limits.
| What it does | |
|---|---|
| 🎮 Game library and launchers | Finds games from Steam, Heroic and Lutris, including native and Flatpak installations. You can also add games manually. Library artwork, source filters and launcher backups are included. |
| ⚙️ Per-game profiles and launching | Keeps launch settings for each game instead of applying the same setup everywhere. GameOpti has its own Steam runner and can apply settings to Heroic and Lutris through their launch configuration. Profiles cover GameMode, display settings, resolution scaling, window modes and FPS limits. |
| 🧠 Smart GPU Scope | Monitors resource pressure during a game session using Linux pressure and cgroup information. When CPU pressure stays high, it can adjust CPU weights for the isolated game and background processes you have opted in to. It tracks its own changes so they can be handled safely afterwards. This is not a custom GPU scheduler and it does not create extra VRAM. |
| 🧩 GPU memory protection | On supported systems, GameOpti uses Linux dmem.low to give a game's GPU-memory allocations priority. This needs compatible kernel, driver and hardware support. It does not add physical VRAM or reduce a game's memory requirements. |
| 🧹 Deep Compression | Analyses a game for files that may not be needed, such as unused language data, language-specific audio, old logs, caches, temporary files and installer leftovers. The analysis checks what can be handled safely; protected or uncertain files are not offered as ordinary cleanup targets. Selected files are moved to quarantine first, so you can test the game and restore them or remove the quarantine afterwards. Deep Compression does not require Btrfs. |
| 💾 Btrfs compression | Uses Btrfs zstd compression for game folders on Btrfs. GameOpti helps compare compression levels, measure storage before and after, track jobs and handle updates. This is separate from Deep Compression: it changes how files are stored, rather than deciding which game files can be removed. A separate deep-recompression operation is available for eligible Btrfs files. |
| 📈 Performance measurements | Lets you record a baseline, test a change and compare the results in the same game and scene. Measurements include FPS, 1% lows, frame times, power and memory where the required data is available. You can keep the change or go back to the previous setup. Results depend on the game and system; GameOpti does not promise an FPS increase for every title. |
| 🖥️ Gamescope and Aqueous | Supports Gamescope and Aqueous as optional compositor choices for runner launches. Their settings are kept separate from the rest of the per-game profile. |
| ✨ Upscaling and FSR | Manages OptiScaler installation, configuration, repair and restoration. Available FSR modes and variants include FSR 4 INT8 Lite and compatible community variants, subject to their own hardware and version requirements. |
| 🧩 DLSS Enabler | Provides a separate per-game backend with configuration and diagnostics. Switching between DLSS Enabler and OptiScaler/Lite is explicit and reversible. |
| 🎞️ Frame generation | Per-game backend selection for Off / lsfg-vk / MAKO Renderer / afmf-linux, with separate settings, on-demand component setup and compatibility checks. |
| 🎨 Post-processing | Manages vkBasalt and ReShade presets, effects, effect order, parameters, shortcuts and per-game restoration. |
| 📊 MangoHud | Per-game configuration with a custom layout, colours, metric selection, placement, preview, FPS limiting and performance logging. |
| 🛠️ Proton tweaks | Per-game compatibility options applied through the launcher that starts the game. |
| 🛋️ Interface | Desktop Mode is available in both editions. Couch Edition also has a full-screen controller interface, controller settings and automatic switching to Couch Mode. Light and dark themes; English, Polish and Spanish translations. |
A few requirements are worth checking before using these features:
- Btrfs compression and deep recompression need the game files to be on Btrfs. Deep Compression does not.
- GPU-memory protection requires compatible
dmemsupport from the kernel and hardware/driver stack. - Gamescope, Aqueous and the graphics backends need their own host or runtime dependencies. Availability can differ between native and Flatpak launchers.
- lsfg-vk and MAKO require a separately purchased copy of Lossless Scaling and compatible files. afmf-linux is an independent project, not AMD's official Linux driver feature.
- Graphics backends can conflict with each other or with individual games. GameOpti checks for known conflicts before applying settings, but it cannot guarantee compatibility with every title. Anti-cheat is not bypassed.
GameOpti 2.2.0 is available as two Flatpak editions. They use the same App ID and user data, so you can switch editions without losing your profiles. Install only the edition you plan to use.
| Couch Edition | Desktop Edition | |
|---|---|---|
| Desktop Mode (mouse and keyboard) | ✓ | ✓ |
| Couch Mode for controller and TV | ✓ | — |
| Automatic switch to Couch Mode when a controller is used | ✓ | — |
| Controller settings | ✓ | — |
| Library, launchers, graphics, storage, MangoHud and measurements | ✓ | ✓ |
Choose Couch Edition for a living-room or handheld setup. Choose Desktop Edition if you use a mouse and keyboard and do not need Couch Mode.
The game pages keep launch settings, Deep Compression, Btrfs tools, graphics options, MangoHud and performance measurements together. Each section has its own settings and status, so it is easier to see which component is being used and what can be restored.

GameOpti is distributed through GitHub Releases, not Flathub. Flathub provides the runtime used by the Flatpak builds.
Add the Flathub remote if it is not already configured:
flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepoDownload one of the 2.2.0 bundles from the release page, then install the edition you chose. The filenames are:
# Couch Edition
flatpak install --user ./Game-Optimization-Linux-2.2.0-couch-edition-x86_64.flatpak
# Desktop Edition
flatpak install --user ./GameOpti-2.2.0-desktop-edition-x86_64.flatpakStart GameOpti with:
flatpak run io.github.DevVoidPL.GameOptimizationLinuxFor Steam profiles, install the user-level host runner:
flatpak run --command=game-optimization-install-runner \
io.github.DevVoidPL.GameOptimizationLinuxHeroic and Lutris use Apply to launcher and their existing launch configuration. Tools must be available in the environment that runs the game, including launcher Flatpaks.
To update, install the newer bundle over the existing one with the reinstall option. To switch editions, install the other bundle; your application settings are retained. To remove the Flatpak version, use:
flatpak uninstall --user io.github.DevVoidPL.GameOptimizationLinuxThe 2.2.0 release also includes an AppImage build. Download it from the release page, make it executable and run it:
chmod +x ./GameOpti-2.2.0-x86_64.AppImage
./GameOpti-2.2.0-x86_64.AppImageGameOpti LXB is a separate project for controller and TV use, with LineXinBar integration planned. Work on the main GameOpti application continues alongside it. See the roadmap for current work and later ideas.
