    Not really although I suppose there may be some HDR-related cases where that would be true. Generally 4x SGMSAA = 4x SGSSAA for polygon edges.

    I just enabled 2xSGSSAA with 8xQ MSAA on LA Noire. Huge difference in IQ. (Drop of 5-10 fps, even more with 4xSGSSAA). Looks great but obviously 4xMSAA+SMAA is going to give me better performance but it will be a little blurrier (I use it for Skyrim).

    How do I enable SGSSAA with nvidia inspector? All I see is 1x2 SSAA, 2x1, etc. I'm playing source engine games.

    Under "Antialiasing - Transparancy Supersampling" you should have options for 2x, 4x & 8x Sparse Grid Supersampling.

    You obviously havent seen the new MLAA 2.0, better than FXAA
    See this

    Been testing it in BF3 & its great. Less fps hit than SMAA (3-4fps vs 6-8fps), IQ almost on par (SMAA still a tad better), no blurring
    I love it now.

    For me im find running x4MSAA with Adaptive (Transparency) enabled, combined with either SMAA or MLAA 2.0.
    = great IQ & no blurring.

    Noob question: Is there a webpage that can actually tells you the differences of all these AA modes?

    I'm confused. Why is SGSSAA under Transparancy Antialiasing? Reading responses, it sounds like SGSSAA cleans up everything (full scene), not just alpha blended textures.

    Depends on the game, and MLAA is ATI/AMD only.

    Top Quality is still Full Screen Super Sampled AA, everything else is a cheaper AA method.

    MLAA 2.0 is the same as MLAA 1.0 quality wise and as for comparing it to FXAA anyone who's interested can do this themselves in DXHR. I prefer FXAA quality.

    Every post-AA solution have blurring because that's the essence of post-AA. Also every post-AA solution have settings which allows to get "less blur/less AA" or "more blur/more AA".

    SGSAA is (personally) one of the best AA methods.

    Unfortunately the FPS is quit daunting if set past 2x

    It does however induce bluring but if you have the GPU power, definitely set SGSAA.

    Seemed to have fixed my issue without format. I ran the un-installer from control panel then re-booted twice. I have to cards and it must be retaining something from the 2nd. Weird, however that's the only thing I did differently and now 301.10 are working for me as before. Phew.. !!!

    After reading all this I decided to start using MSAA + SGSAA as a couple, forcing MSAA 2x(4x)(8x) with SGSAA 2x(4x)(8x) thx to inspector, also adjusting LOD bias.

    Question is, when it goes to x8, should I pair SGSAA 8x with AA 8x (CSAA it says) or AA 8xQ (MSAA it seems)? I use 8xQ so far.

    I really didn't like the FXAA. The blurring is shocking imo, it removes all details from the screen so it looks like PS2 haha. But yea, I confirm, SGSAA actually adds some blur, but just a few.

    But you like SGSSAA blur because you read that it's high-end, while FXAA is a ghetto solution, is that it?
    This is from Mr. AA himself - T. Lottes:

    Anti-aliasing is always a trade off with sharpness, even when done correctly by super-sampling and a proper down-sampling filter.

    Not to mention that SGSSAA with improper/non existant AA bits may clash with post-processing, resulting in additional blur.

    Now tell me where do you see this PS2 blur?

    Nothing but FXAA is used

    I'm in the same boat as the O.P. here, a big wtf over all the letters n such. After reading the thread, well... it could be the medication.

    Hi Noisiv, plz don't get me wrong. The PS2 thingy was a bit sarcastic I agree.
    Tbh I would have welcomed FXAA if I wasn't killing my eyes on the title I tried. I don't rely on company screenshots but I can tell you that in Mass Effect 3, the difference is huge on my 46" screen. On Skyrim indeed I tried to combine FXAA with MSAA and it looks good and cheap, but SGSSAA is definitely sharper but much heavier.

    And wait, I just bought myself a new 680 GTX right? So let's go :) Imo FXAA is a good solution for low/mid rigs (I actually use it on my laptop 9800 GTS 17" with low def 1440x900 and I love it) but when you're running a high end rig you want all the eye candies you can get, and SGSSAA so far is the winner. But I may be wrong heh, I discovered SGSSAA one week ago lol

    Regards

    with you there Noisiv - some people talk about fxaa as if it's like looking through frosted glass. just don't see it myself - what i do see is great anti-aliasing (better than MSAA in some ways) with almost zero performance hit.

    replaying the Bioshock's at the mo - they looking amazing with fxaa enabled.
    tip for those who get a sudden urge to replay these games - tweak the ini's to disable the built-in software AA and texture filtering (UseSoftwareAntiAliasing= and LevelOfAnisotropy= in Bioshock2SP.ini), then force/set as many quality options as possible in the NVCP.
