The record

What it does: GameMode is a daemon and library that lets games request temporary optimisations to the Linux host operating system or game process.
Optimisations: Supported optimisations include CPU governor, I/O priority, process niceness, scheduler policy, screensaver inhibition, GPU performance mode, CPU core pinning or parking, and custom scripts.
GPU support: GPU performance mode is supported for NVIDIA and AMD, and GPU overclocking is listed for NVIDIA.
Game integration: Games and launchers with GameMode support activate it automatically; other games can be started with the gamemoderun command or Steam launch option.
Linux distributions: The project lists packages for Ubuntu, Debian, Solus, Arch, Gentoo, Fedora, OpenSUSE, and Mageia, with possible availability elsewhere.
Configuration: GameMode uses a gamemode.ini file, and its example configuration documents options including GPU, CPU, filters, supervisor access, and custom scripts.
GPU settings caution: The example configuration warns that GPU optimisations such as overclocks are used at the user's own risk and that resulting hardware damage is the user's responsibility.
System requirements: The project says its build depends on Meson and its internal communication uses systemd; development also requires a C development environment.
Limit: hybrid graphics: The README says GameMode cannot automatically integrate hybrid GPU commands such as optirun after the game has started, but describes using a wrapper with gamemoderun.
Support route: The README asks users to report GameMode issues in the repository's GitHub Issues section rather than directly to Feral.
License: GameMode is available under the BSD 3-Clause License (Revised).
Maintainer: The repository identifies Feral Interactive as the maintainer of GameMode.
Maker history: Feral Interactive says it began in 1996 with a mission to bring games to Mac.
Founded: 1996
