There's 1080p/60fps, 4k/30, and something in-between that's 1440p/60 i guess, in case you don't have 4k or something.
Also, doesn't 4K automatically reduce pixel size, reducing edges?

The problem is that no matter what you do to low resolution textures/low polygon count visuals, it'll still look low quality. Think of games on ps2 and playing them on a 1080p tv, the low resolution textures and low polygon get more exposed. Sure you'll get better anti-aliasing (non-choppy edges) but there are exponentially better ways to handle choppy edges that don't require us spending $800+ on a computer monitor.
The game looks and feels great, the only slight issue I noticed is in Limsa during peak times.
I'm just hoping the PS5 can handle even more, that is in case they will improve the game's graphics much in the future.
Hopefully it is future-proof enough for the game.
