This may be more relevant for steam-runtime instead of Proton's repository.
Hello @Tiagoquix, this is out of scope for the Proton project.
In general, the tuning of hardware is something for a distro / hardware vendor to decide (or your personal decision of course), not for individual games or a compatibility layer or Steam to micromanage.
Nothing extracted yet.
Feature Request
I confirm:
contain this feature already.
Description
Request GameMode by default in all games if available in the host system ( https://github.com/FeralInteractive/gamemode ). Maybe also add gamemode package as a weak (recommended) dependency when installing Steam.
GameMode optimizes PC performance when playing.
Justification [optional]
Risks [optional]
Desktop compositor will probably be disabled, killing desktop animations while the game is open, but I think this is already done even with no GameMode (compositors do this themselves for full-screen apps).
