Where is the "Game Mode" notification?

[MBX]

Hey isn't there a notification when MacOS Sonoma goes into "Gaming mode" that utilizes more power?

So far I haven't seen any notification when launching Steam or other apps utilising a lot of power.

I tried with Minecraft and got a notification. Maybe try to launch a specific game rather than steam? I wonder if the game has to be Apple silicon native to enable game mode

It works with Intel games too. It works with all App Store games I installed, but only with some games I downloaded from GOG. One common thing I found so far is that those games that trigger Game Mode have this in the Info.plist file:

<key>LSApplicationCategoryType</key>
<string>public.app-category.games</string>

(It might be something more specific too, such as public.app-category.adventure-games.)

However, this is not enough. I searched the developer documentation, but have not found any clues.
