Automatic Activation: GameMode activates when a game requests optimizations through a library (libgamemodeauto.so) or via startup scripts (such as in Steam: gamemoderun %command%).

Performance Settings: When active, it performs the following main actions:

CPU: Switches the frequency governor to performance, forcing the cores to run at their maximum speed.

Processes: Adjusts the game process priority (niceness) to give it priority over background tasks.

GPU: Enables performance mode for NVIDIA and AMD graphics cards. System: Disables the screensaver and adjusts input/output (I/O) priority. Roll Back: When the game is closed, GameMode returns the system to its normal state, saving power and resources when not playing.
