Admittedly, I don’t use game mode as often as most. I do gamedev on this, so it’s almost always in Desktop mode, even when I’m actually playing games.
Having said that, the handful of times I have used it on Cachy felt no different at all to SteamOS. The UI is identical. They did a great job recreating the Valve-specific parts of SteamOS that aren’t just part of KDE or Arch.
The only downside, and it’s just a minor inconvenience for me, is that Cachy doesn’t have the option to boot into Desktop mode by default (yet). It always boots up into game mode first.
EDIT: I was wrong, the game mode on CachyOS is actually one in the same as SteamOS game mode. That is something built into a special release of the Steam client for Steam Decks, and Cachy just uses that instead of reinventing the wheel. It should be a direct 1:1 experience when it comes to game mode.
