GameMode for Linux consists of a daemon/lib combo that allows games to request a specific set of optimizations to be temporarily applied to the host operating system and/or a game process. This can help improve the gaming experience by optimizing system resources for better performance while the game runs.

GameMode for Linux was initially developed as a temporary solution to address issues with the Intel and AMD CPU power save or on-demand governors. Over time, it has evolved to offer a wide range of optimization features and configurations tailored to enhance performance on Linux systems.
