I'm playing Magic: Arena on my M1 MacBook Pro. It's a game that's available exclusively through the Epic Games Store. There is no way to show the frames per second inside the game. There used to be, but the developers disabled the feature at some point.
The reason I would like to see the frame rate is to help me choose the ideal graphics quality level for my machine.
I tried the Count It app, but it just stays at zero when trying to measure it. Also, it's authors say it's unstable and it hasn't apparently been updated in the last four years.
