So if you want your gameplay to be as detailed as possible, then you'll want the 4K / 30fps mode, but if you want it to be smooth, then there's a 60fps option that can drop its resolution down as far as 1440p.

God of War PC runs in native (not upscaled or checkerboarded) 4K 60Hz with ease, and we've noticed framerates very close to 120Hz, as well.
