It depends on which method of AA to large varying degrees, But they all blur, as is literally their function. For whatever reason, at 1440p, my eyes and brain overwhelmingly recognize shapes and depth better and way faster with no AA. To me, applying DLAA is like another layer of filter over what I'm seeing. My goal is to have a level of pixel density per degree of field of vision where pixels or jaggies are indiscernible at any level - and then I'll enable AA as a kind of ultra fine dither. I know that sounds directly contradicting, but it makeS sense to me.

Edit: it's important to remember that this is a game and not a still photograph. If the game is less a game and more an interactive film, then maybe I'll leave aa on. But generally I like to play games when I want to play games, and watch stuff when I want to watch stuff. Good questions to ask yourself when playing a "game" is: "Is this actually a game? Does it have a fail-state? What is the fail-state?" A lot of "games" these days are barely or not even games, and even within the game category, there's a lot of what I'm now calling Darkslop, which is garbage games filled with dark patterns by the devs. Most "live service" "games" are Darkslop
