We all want to get the best performance out of our Linux games and Feral Interactive's GameMode tool continues to help towards this. While the initial release of GameMode was quite limited, they haven't stopped working on it.
They've just announced the release of GameMode 1.3, which adds in a bunch of pretty useful features including: disabling the screen-saver, a "gamemoderun" helper script to do the necessary setup (set LD_PRELOAD) to enable GameMode on games which do not support it themselves and increase I/O priority of game processes.
All of that sounds quite nice but there's two other pretty huge features added in this release. For those with either an NVIDIA or AMD GPU, there's now experimental overclocking/performance level configuration.
They also noted "Various other minor fixes and improvements". See the release notes on GitHub here.
I really hope this tool keeps on advancing, I've no doubt there's plenty more ways for them to keep pushing Linux gaming performance further to benefit everyone. The fact that Feral aren't keeping this for themselves, is also another reason to love what they do, it also means others can help make it even better like with this release having multiple authors.
One of the contributors, Marc Di Luzio, who previously worked for Feral Interactive and now Unity (while also doing tooling for Valve) teased on Twitter "More cool things to come, now that some foundations have been laid..." which sounds interesting.
