GameMode is a daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process.

It was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is now host to a range of optimisation features and configurations.

Currently GameMode includes support for optimisations including:

• CPU governor
• I/O priority
• Process niceness
• Kernel scheduler (SCHED_ISO)
• Screensaver inhibiting
• GPU performance mode (NVIDIA and AMD)
• GPU overclocking (NVIDIA)
• Custom scripts
