High-resolution gaming reduces the need for anti-aliasing?

  1. May 26, 2011 #1
    I have a 1920x1080 monitor and a powerful enough rig to playably run any of my games on that resolution, even Crysis. I heard that AA (anti-aliasing) isn't necessary at high resolutions. And that adding AA at high-res is almost completely unnoticeable, and it only murders your framerate.

    The only function of AA is to make jagged edges appear smoother. I believe high resolutions has this same effect, eliminating the need for AA. Although high-res AA might have some effect if you look very close. But otherwise it is mostly unnoticeable.

    I play games on 1080p with 0x AA and I do not see any jagged edges. But when I reduce the resolution, the jagged edges become very obvious.
    Anisotropic filtering (AF) is a different story.

    So low resolution + AA or high resolution - AA?

    Not to mention that turning off all AA (especially at high-res) significantly improves your framerates.

    It appears to boil down to how sharp your eyesight is. If you don't notice the aliasing, you don't need the AA software.

    I don't notice any jagged edges at 1080p, so I disable all AA. Doing this can mean the difference between getting a silky smooth 60+ fps, and getting <25 fps. Especially in games like Crysis.
