I think Pillars Of Eternity on Macs is not reading the OS resolutions list properly. The game shows me 1920x1080 with 60 Hz but the result in fullscreen is in real only 1080i which is blurry and looks all jittery. The game immediately forces interlaced mode at the 1080-resolution and this looks awful. Even with 1600x900 it looks better. Got this problem with the game „Divinity: Original Sin“, too but the developer fixed it after I told them
