    Except that TXAA is actually WORTH something and improves so much for so little cost.

    Minor blur=/= bad quality

    Look at SMAA's own Comparison video of SMAA T2x
    http://www.iryoku.com/smaa/downloads/SMAA-Enhanced-Subpixel-Morphological-Antialiasing.mp4

    SMAA remains "blur" free, but it's anti aliasing quality suffers as a result.


    It basically makes temporal aliasing only flicker slightly less than it does without it.

    Infamous Second Son uses it, and it still leaves a bit behind

    MSAA > all, yes it has big performance impact but no blur at all.FXAA/MLAA are the worst AA out there.

    Then you aren't touching shader and transparency aliasing... not a real solution.

    Doesn't remove shimmering, only temporal AA does like TXAA.

    As games use more complex pixel shader effects and fine surface details, the multi-sampling becomes less and less effective at countering the higher order specular/texture aliasing. CSAA was simply an ad-hoc for the MSAA to provide more accurate pixel coverage solution for the geometry, using only the depth buffer information. But as the MSAA itself, it simply bypasses the pixel shader and texture stages of the pipeline.

    With the advent of the various easy to implement and fast post-process AA methods, developers will definitely not bother anymore to twist the graphics engines to make them hardware multi-sampling compatible. And for some titles, there will be a high-quality option with a plain brute force super-sampling (Thief and Trine, for example).

    And how many games use TXAA, 3-4 max, right.. Just a Marketing thing to sell more 600 series.
    Also its still ****ty overall, you can defend it if you want, idc.


    Anyway they better make something better with Maxwell, usable in all games not strictly bound to game engine :laugh:

    I don't care about shimmering, i want crystal clear image.

    TXAA x2 does a LOT better job than MSAA x8. Period.

    At making a blurry mess you got it.

    To each their own. I don't like the blurry imagery.

    FXAA if done right I can handle.

    As for CSAA, it was nice as an option, but does not bother me to see it go if it infact does.

    MSAA is still my choice.

    FXAA blurs everything up in exchange of... what exactly? Pretty much everything is still horribly aliased. So in the end you have jagged blurry imagery. Wow, what a success.

    If post-process AA, then SMAA, not that ****ty garbage FXAA.

    As for MSAA goes, up to 50% of scenery is STILL aliased. How is that helpful?

    If only you knew what you talked about.

    TXAA blurs the image way more than FXAA will any day. Get glasses or something then take a look.

    Watch how textures and Tessellation blur into a clump.

    FXAA if built into the game and used correctly looks just fine.

    SMAA is best sure, and should be used more often.

    FXAA is pretty meh for diagonals too, SMAA has massive advantage there too. Though, sometimes I hope that SMAA would be tiny bit more aggressive (it tends to miss more edges, even with 0.01 threshold).

    It would be great to see more SMAA S2x, SMAA T2x or SMAA 4x implementations.

    So, games like Serious Sam 3, Trine 2, or BioShock Infinte looks fine with their built-in FXAA? Yes. Yes they do. But only with SSAA, which means BSI is just blurry mess. No matter how well used, FXAA still blurs everything, while 80% os screen has aliased edges. Again, how is that helpful EXACTLY?

    ^
    I dont use SS3 ingame fxaa its ugly, driver fxaa is better if i have to use it, but im happy with just 4xmsaa, also clearer image.

    I prefer game detail over blurry mess, even i have to see some jaggies and again how many games use TXAA again? Right, same like CSAA, it will die and be forgotten sooner then later.


    edit: Dont get me wrong, it looks good on paper and newer 2-3 games have better implementation, but its still kinda like fxaa+ msaa in the end.

    And to make it so limited is another bad example, although its possible on older Fermi arch.
    I could enable it in COD Ghosts and Batman Arkham Origin, but they patched it later xD

    its like sweetfx injector dll
    Txaa.win32.dll (~ 80kb)

    MSAA 4x killed my framerate in Crysis 3. TXAA 2x did not. And there was barely any aliased edges. Blur wasn't bigger than with FXAA, so win-win situation for me.

    Ill take MSAA+SGSSAA and turn on the LOD Bias to combat blurring. Ill take this over any other type of Anti Aliasing atm. Heavy hitter on the performance mind you but worth it.

    Exactly.

    MSAA/CSAA only handle Geometric elements. Which does tackle SOME Pixel crawl, but ONLY geometric.

    It doesn't do anything for the temporal aliasing thanks to shaders, specular lighting,moire,texture aliasing,etc.
