So I don't know what subform this should be posted in but I'm guessing this is mostly a OS issue so we try in this forum.

For the record this is on a M1 Mac Mini

So I have a monitor that has Adaptive-sync and allows some degree of variable refresh rate. In monitor settings I also have the option to use variable refresh rate so I have used it (in my case it says it will vary between 48-60 Hz so the variability of my monitor is limited).

I recently started to play Path of Exile (PoE) and there I noticed that having v-sync on and the variable refresh rate option in monitor settings (of MacOS) turned on it capped the FPS in the game to 30 FPS. Turning off v-sync of course gave me a higher FPS that varies a lot and results in a lot of tearing.

But here is the kicker setting the monitor to just 60 Hz in monitor settings (of MacOS) and running the game with v-sync on gives me the result I expect from variable refresh rate. When not too much is happening on the screen the FPS varies (as a result of v-sync) between 48-60 FPS, no tearing. Of course in intense scenes the FPS can drop further (BTW PoE is fully playable and enjoyable on M1 Macs if you can live with a bit lower graphical fidelity, you don't even have to run everything on min settings)

I have no idea if this is a result of PoE itself or it being run through rosetta. And I have no idea how to try this with something else.

Anyone else noticed this or maybe knows why it is like this?
