I was referring to "Steam games" not (obviously) "the Steam client". a) Not all Steam games are on Proton [https://www.protondb.com/ https://www.protondb.com/] b) Not all Steam games that are on Proton run efficiently without tweaks e.g. one that I found unplayable due to overheats (on MacOS) was Sid Meier’s Civilization VI [https://www.protondb.com/app/289070 https://www.protondb.com/app/289070] c) Not all Steam games where you had the pre-Proton version installed, download the right version update. See Steam's forums, people saying disable Steamplay; and have to do that globally, not per-game. d) In addition, I found the Steam updater daemon (interacting with MacOS Mojave Quarantine) also burned power like no tomorrow.
