    I know it's the end of summer, and christmas is still a little far, but i have something to share with you guys.
    So what i'm gonna show works both on nvidia and amd, but since i have an R9 290X i'll post the thread here.

    We all have some preferred anti-aliasing method, some people preffers the fxaa method (fast but blurry),
    others msaa (sharp but often implemented with feets i guess), but Downsampling anti-aliasing stays the king (in quality of course, but you will have to do a lot of compromises to play at 60fps).

    Long story short, i found a way to get the sharpness quality of downsampling with the performance of fxaa.
    so first we will not use any ingame aa, because they are rarely optimised.
    Instead, we will use Sweetfx to applly smaa, but also fxaa at the same time, and we will add to it lumasharpen at it max to get rid of the fxaa blur.

    if you want to try it out, i uploaded this "ready to apply" .rar, Enjoy!!

    I have tried that and it ends up being too grainy for my taste.

    you can try to lower the lumasharpen strength and see if it's better for you, but this AA method let you save a lot of horse power to play every game in ultra settings!! :)

    I was not expecting much scrolling through the images, but damn that's one hell of a result.

    Thanks OP, you should drop this info into the Nvidia thread also.

    You link is dead btw, can we please get a reup or settings please.

    sorry but your downsampling picture is not 1080p resolution but 1600p...
    thats why it looks worse than your enb/sweetfx solution.

    pls try again.

    btw. try the combination of both... OpieOP!

    if you open the 3 pictures in the post by: right click>"open picture on a new tab" you will see the picture donwsampled.

    I think this just applies to GTA V cause finding an AA solution that works is just plain hard. MSAA is too taxing and only viable at 4x, SMAA doesnt do do a great job and FXAA is decent.

    I never thought to try FXAA and SMAA together though. I started playing again last night and will be trying this right now. If its similar to 4X MSAA : ill be very happy. The i can crank up some other settings.

    You will still get shimmering edges with post-processing AA.

    Maybe, but anti-aliasing takes too much resources, this solution let you turn off ingame AA (they are often poorly optimised) , also to let down downsampling (since it takes to much resources), so you can spend all your gpu power on graphics quality

    I have been doing FXAA and SMAA together for the past couple of years now.
    Never thought about posting about doing it.
    I used FXAA for the areas where SMAA seemed to miss.
    And used a little luma sharpen to clear it up with a touch of vibrance.

    Not bad, although I still prefer the quality of RGSSAA/SGSSAA. ;)

    yes, downsamping is the best, but in some games if you play on ultra with let's say 1440p, the fps can drop from 60fps to 22fps.
    in the other hand, this solution can save you all resources that you usually spend on antialiasing. also, it gives you sharpness very close to downsampling with performance of an optimised fxaa. :)

    None aa method can be compared to downsampling/supersampling/vsr/dsr as these just render image in much higher resolutions and that's essence of their quality.

    Personally i prefer post-process methods as they are not killing performance that much and i'm combining various methods since long time and to do so i'm using sweetfx. This means i'm combining fxaa and smaa since as long as possible.

    GTA 5 is curious case. IMO it has more aliasing than most other games. Usually i'm satisfied with look of games at 2560x1440 resolution but gta 5 is the only case of a game in which i still see aliasing at that high resolution.

    Ok, back to topic... This combination is not better than downsampling/ssaa/vsr/dsr because it is still combination of just post process methods of aa which doesn't add any quality to image but smoothing a bit of some edges. Also it would be nice to try to combine more methods together and look at output of such combination. SMAA, fxaa, mlaa, nfaa, dlaa... and many other post-process methods, anyone knows how to combine them all? I'm able to combine up to three methods together: fxaa+smaa with sweetfx and mlaa via ccc.

    BTW, in bf bad company 2 mlaa forced via ccc causes changes to look of fonts in the game.

    There are few universal AA recipes.
    When fiddling with AA it should be done per game, per resolution/screen size basis.



    In above example Smaa+FXAA is not better than that Downsampling.
    Look at the fence in SMAA+FXAA - its smudged all over.

    Also it's not a very good comparison:

    Add SMAA(or FXAA) to that downsampling and for a tiny perf. hit it ends up better than SMAA+FXAA. Even in stills. And SMAA/FXAA are good in stills

    Ingame, in motion, Downsampling is much better because it gets rid of pixel crawling too.

    Specifically for GTAV, 2560 VSR @1080p(24'') all the way.

    There is no doubt that downsampling is the king, but it needs a lot of ressources. that's why we try some postprocessing solutions. We are looking for a SMART way to get rid off jaggies, BTW there is some Project cars creenshots:

    I use negative lod instead of sharpening along with driver fxaa. Been using it for several months now. I like the effect better than luma sharpen, or any other sharpening filter.

    Skyrim is the only game where I use a +ve lod bias(no fxaa). No clue why, but whoever made that body texture (yes its a weird japanese blogger) said it will give the best results, and it really does.

    Edit, tried your prepackaged stuff, works great for GTAV :D
