Enable GameMode to Boost your Linux Performance on Demand

According to Gamemode's Github page:

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.

In my opinion, this is the kind of things that Linux ecosystem lacks the most. And I don't mean gaming, but quality of life kind of thing. Switching CPU governors back and forth just for juicing out the last bit of performance is no fun. Nevertheless, GameMode provides much more than just CPU tweaking but:

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

Usage

Run programs or games with GameMode:

gamemoderun path/to/binary
Bash

Or prepend gamemoderun to your shortcuts' command:

Verify GameMode is On

To see if GameMode is enabled:

gamemoded -s
Bash

gamemode is active
Output
