    AMD has released its 6XXX cards for a couple of months, since then, you could find a new feature called
    ”Morphological filtering” in CCC control panel. Everybody knows it’s the newest AA solution for fashioned
    games, but it may cause some problems in some circumstances.
    In my opinion you take the advantage and you suffer its drawback, that’s all.
    Below is my little test of MLAA and excuse me if the games are a little older then you expect,
    also I am not a devout win7&dx11 enthusiast~~


    You can set “Morphological filtering” enabled by clicking the check box in CCC panel.

    1、ABOUT PERFORMANCE
    set 4aa/8af in driver or built-in options to run all tests,
    set morphological filtering on/off to see the difference

    MY PC:E6500, 4GB RAM, ASUS HD6850
    DRIVER:CCC 11.8
    BENCHMARK:3DMARK05、3DMARK06、CRYSIS、LOST PLANET 2

    3DMARK05 MF:OFF

    summary
    [​IMG]

    Several months ago when I enabled morphological filtering, there was a dramatic performance drop,
    now it has reached a reasonable level, and you could just set it on and not to worry about the performance.
    Not all games are so pleasant though, due to different 3D engines or other technologies used in games…





    2、ABOUT Anti-Aliasing
    All pics below are 4AA/8AF screenshots captured by FRAPS.
    You could discover when facing light source MLAA does a great job,
    and it improves normal AA as well.

    3、ABOUT TEXTURE
    When MLAA is enabled, textures become a little blurring,
    details are lost due to calculating method of MLAA.
    Texts on screen also suffer the same problem and may become illegible because of small fonts.

    CRYSIS:shadows are more stereoscopic when MLAA is off
    the right pic(MLAA on) is a little out of focus.
    [​IMG]

    CRYSIS:take a close look at the surface of the plank, the dust on the left is more vivid, isn’t it?
    [​IMG]

    FALLOUT - New Vegas:textures on the right(MLAA on) are a little vaugue,
    the wood planks and soil reveal more details when MLAA is disabled.

    I disable it now, as you have mentioned, I get blurring of the visuals plus text, for me, the cons outweight the pro's. nice comparisions though!

    I enjoy MLAA in Starcraf2. A good solution that cleans up an game nicely, but the effect on in-game text is a bit of a deal-breaker for me. And if you happen to forget to switch it off after a game... you have pretty messed up text in just about everything.

    The positives do outweigh the negative effects though. Good shader/compute AA algorithm, minimal performance hit, and forced AA in all games...

    Try supersampling in New Vegas, you won't be disappointed, I find the only good use for MLAA is GTAIV, any other game the text gets too blurry.

    MASSIVE PROBLEM WITH FIREFOX it plays havoc with Firefox because of the filtering on the text.

    Use RadeonPRO to set profiles for each game.

    I have used it and low and behold that if you check the "use application settings" unless firefox or other apps are requesting AA it isn't used.

    It does suck for games like Morrowind though, it blurs it som uch at high settings that it is useless.
