    They are saying that TXAA is a MORE EFFICIENT form of AA which gives you the effect of 8xMSAA but the performance hit of 4xMSAA. This isn't rocket science. If it can be used on prior generations, there is no fundamental reason there should not be a similar PERCENTAGE wise increase in performance.

    No bro, it's true.

    It blurs textures, and well everything.

    It's best used on lower end hardware since its a faster method of AA.

    Depending on the game it's more noticeable than in others.

    In the latest drivers (304.79) it doesn't. In fact, it sharpens textures a bit, and leaves almost no jaggies @1080p. AND it costs as much performance as 2x MSAA, and gives the quality of 6x or more. I tested it in Skyrim, Mass Effect 3 and other games, and now I don't use MSAA anymore. Also, I really believe MSAA is an inefficient method, since the frame-buffer workload increases exponentially as you increase the samples.

    You may not like FXAA, but it's the future of Anti Aliasing.

    In this case, rocket science is called MARKET SCIENCE! :)

    I'm only glad nVidia gave me the FXAA option, it's good enough for me and my 1080p 23'' display!

    It may blur fonts and other stuff, but it's getting better at each release. FXAA is designed to detect the limits of each polygon and remove the jaggies there. It doesn't mess with the textures, just applies where needed. Check the nvidia documents.

    It makes things blurry man. Known fact. That's why its known as the poor mans aa where as other forms of aa will cripple lower end cards

    Dude it BLURS everything. Only games designed with it does FXAA not apply to HUD or other on screen things.MSAA looks at edges and polygons. FXAA does not and affects ALL pixels on the screen.

    Doesn't blur anything on my system, at least. Images are crystal clear!

    I'm glad then... :banana:

    True... I know you guys are trying to justify your big investment in your SLi setups using 16x MSAA...

    Sorry, but I find FXAA cool, and it DOESN'T blur game graphics in my system, in fact it looks SHARPER and removes a great deal on the jaggies. :stewpid:

    Calling me ignorant wasn't a polite move, but I'll ignore that.

    It blurs things a little bit, if it didn't then Nvidia wouldn't be spending so much money and time pushing this (TXAA) so much, Nvidia even mentioned that FXAA caused the textures to blur in the previous driver when they added MSAA compatibility for Diablo3.

    I use it nearly all the time as it tends to deal with aliasing better than MSAA does, especially with new engines, and i will only be ocd about the blur if i spend too much time comparing it to the image without it enabled.
    With it disabled i will always notice the aliasing, so FXAA is the lesser of two evils.

    sapo_joe might mean FXAA makes things look sharper as sometime an detail can be lost when you have an overly aliased image.

    If it blurs, it's really barely noticeable and on very certain scenes. You got me right, it looks better IMO, because of the way it acts. MSAA just divides the number of jaggies, FXAA REMOVES them by intelligently detecting them, as a post processing shader.

    TXAA is another evolution in the anti aliasing tech, as you can see here: http://www.geforce.com/landing-page/TXAA

    TXAA combines MSAA and post-processing to remove the jaggies and shimmering on the moving images. Of course, it's an engine-level anti aliasing technique, and won't be supported by older games unless developers want to get on board.

    I actually have a 10/10 sight. Maybe the problem is with yours.

    ORLY

    Syndiacte: A game with pretty low texture quality in areas that would by ALL MEANS BLUR SO MUCH (Generally such is the case. The stigma is that low quality textures get blurred)

    But look

    Syndicate: No FXAA
    [​IMG]
    Syndicate: FXAA
    [​IMG]

    No texture blurring at all. The only thing that gets affected is aliasing.


    Using FXAA with other forms of AA like OGSSAA(Downsampling) and Injected SMAA, or MSAA+TrAA is the perfect way to get near aliasing free picture quality without the performance hit of SGSSAA.

    (And in this case of Syndicate, that is with 4XMSAA+4XTrAA. And then that + FXAA)


    Just look at Binary Domain w/OGSSAA+FXAA
    [​IMG]
    [​IMG]
    Yeah it's sooo blurry! /Sarcasm


    Just for the record: FSAA=Full Scene AA, basically Supersampling, processes the whole scene. SGSSAA is also a form of FSAA.

    MSAA was a hack that derived out of necessity because of the performance crippling nature of FSAA back in the day. It only Anti-aliases Polygon edges and does nothing to combat shader aliasing, or alpha tested objects like sprites and other stuff.

    And in Today's market of Games MSAA just doesn't cut it in a lot of games. ESPECIALLY UE3 games.

    In fact I do. But I'm too tired to explain it to you now, so go google it yourself.
