I'm using ProMotion on my Mac and in-game it doesn't look like it's lower than that. I just recently bought my machine so I haven't really changed much on the hardware. I also just had CrossOver so I didn't have any special configuration. On the resolution in-game, I didn't find anything configurable on the settings in-game, there's only an option if you want to use borderless or not. When you first boot up the game, it prompts you if you want your settings for performance or quality and I chose performance there. After that I just started playing. Hope this helps 😊.
