nerdzmaniaUpdate on my previous post regarding Bazzite on an old iMac:
I have had issues running some games, for example: I could not get the Rockstar game launcher to work so no GTAIV, can't launch Doom 64 either. Note that I didn't do any advanced tweaking, I assume it's possible to get those games to launch somehow.
I tried Wolfenstein: The New Order, it launched without any issues but even with the graphics set to Medium, the framerate is kinda choppy, so this computer is waayy underpowered for today's gaming standards.
But anyways, all things considered, Bazzite exceeds my expectations, I'll keep that OS on this computer and see how things go.
