Video games within Gnu / Linux is a problem that worries many users. Not server administrators but developers and desktop users who think or need to run games on their computer. More and more advances are being made in this field and that means that some video games are already available for Gnu / Linux, Steam users know it very well.
But, for those who do not use Steam, a very interesting advance has been made, a daemon named GameMode has been released and that will allow the use of videogames to be more suitable within Gnu / Linux systems.GameMode is a library / daemon for Gnu / Linux that has been created by the Feral Interactive company. This company, concerned about the consumption and performance of Intel and AMD GPU boards, decided to create this demon that what it does is adapt the performance of the CPU according to the needs of the video game and always without damaging the rest of the computer's hardware.
GameMode is a daemon that makes us a frequency scaling of the CPU
That is, GameMode does CPU frequency scaling so that the video game has all the power that the CPU can offer, without any limitation and offer the best gaming experience for the user. GameMode is compatible with Systemd, so it can only be used in distributions that have this system.
Regrettably, GameMode is not by default neither in the company's games nor in any official repository, but we can install it in any distribution. For this we just have to go to official GitHub repository and follow the instructions that the developers have set. At the moment, GameMode only does this but it is not ruled out that a version will come out that also improves other facets of video games or that it is present in Feral Interactive video games for Gnu / Linux.
