It's not an issue, but maybe this is anyhow possible: ProMotion Display: 25fps (M1max)

Hey Guys and Gals,
I have no Idea about programming, but I wonder if it's possible to set Apple's ProMotion display to a certain frequency, which is not in the list. I do live renderings - currently on 50 Hertz - but I have the feeling that I could save performance - and energy - if the refresh rate of the display (and with it all the displayed things) - are live-rendered/refreshed at/with just 25 times a second, instead of 50 times. The final live rendering has a target fps of exactly 25 fps. Sometimes I'd need the same but for exactly 30fps.

Thank you so much for considering and/or thinking about (this maybe weird) thought.

Thx so much,
Jo
