What is GameMode?
GameMode was created by the Steam community to provide a lightweight way to boost game performance on Linux. It runs a small background service that temporarily raises process priority, locks memory, and disables power saving features while a game is active. The project has been maintained for several years, with regular updates across major distributions.
It targets gamers who want a quick, system‑wide performance boost without diving into manual tweaks. The tool is simple to use: launch a game, GameMode automatically detects it and applies the settings.
Compared to Xbox Game Bar, GameMode is more focused on performance than on UI overlays. It doesn’t provide a dashboard or streaming tools, but it does the job of keeping your CPU and GPU at full potential while you play.
Best for: Gamers who want a quick, system‑wide performance boost without extra UI overhead.

How to install GameMode on Linux
sudo apt install gamemodesudo apt install gamemodesudo dnf install gamemodesudo pacman -S gamemodesudo zypper install gamemodeTips for Windows users
If you’re used to Xbox Game Bar, GameMode won’t replace its overlay or streaming features. Instead, use GameMode for performance while keeping your usual Windows‑style tools for chat or streaming. GameMode works with any game format; just start the game and the daemon will detect it. No file format conversion is needed. You can also set custom profiles via a simple config file if you need specific tweaks.
Workflow: launch the game, GameMode automatically applies settings, you play as usual. If you want to stop it, simply close the game or use the command line to disable the daemon.
Shortcuts: there are no special shortcuts; you can enable or disable GameMode with the command gamemode on or gamemode off.
Overall, it’s a silent helper that keeps your system ready for gaming, but it won’t replace the UI features you’re used to on Windows.
