    I'll add a comparison either tonight or tomorrow. Busy day :p

    It manages to sharpen the image a bit.

    Are there any documented cases where the AA fix is detrimental?

    I'm just thinking its better to keep it on all the time in case it doesn't do any harm.

    Would save some time when you start a new game and don't have to check if it needs AA fix or not.

    Made a report on Alien Isolation.
    The game includes FXAA, SMAA T1x and SMAA T2x.

    No AA: http://i.cubeupload.com/qImKJ3.png
    FXAA: http://i.cubeupload.com/2Q4KgZ.png
    SMAA T1X: http://i.cubeupload.com/00iqFi.png
    SMAA T2X: http://i.cubeupload.com/DnQJYz.png

    None of them seem to provide satisfactory AA method, but SMAA T2x is definitely the most desirable.

    Personally I'm using 1.5x SSAA (through downsampling from 1620p to 1080p) combined with ingame SMAA T2x.

    1.5x SSAA + SMAA T2x: http://i.cubeupload.com/sJUBIt.png

    There still is some temporal aliasing left, and since the game is DX11 only then there's no chance for SGSSAA.
    I can't try 4K downsampling since my monitor doesn't go higher than 1620p.

    All screenshots at max possible settings, taken at FOV of 75 (maximum allowed by the game, but it seems that's vertical FOV so it's good), film grain and chromatic aberration turned off since I don't find these effects desirable.

    Good to see more AA offered, but in all 3 cases that i've seen anything more than standard SMAA 1x, SMAA T2x and SMAA 4x are both crap compared to SGSSAA. But still better than nothing.

    SMAA 4x in Crysis 3 in particular is only OK. And leaves tons of temporal aliasing behind even when downsampling and doesn't do anything for harsh specular aliasing. Of which Crysis 3 has a ton of. Not to mention there are some crazy flickering issues when looking at certain angles with it.

    SMAA T2x in Dead Rising 3 is downright bad. Not only does it not reduce much if any at all temporal aliasing. It's even worse than SMAA and FXAA in a lot of ways. And has ghosting/smearing issues.


    Even with 1.5x1.5+SMAAT2x in your shot, it's shocking but not surprising how much aliasing is still left.

    1.5x1.5+4xSGSSAA would decimate just about everything.

    What do you use for that? Old method with fake resolution modes or DSR? Or something else?

    Custom resolutions in Nvidia panel.
    I also managed to get 4K working after all.

    I updated the post with the info you requested. Also, since you are good with AA bits, if you think there is a bit to improve the blur (most likely unavoidable), please share haha.

    No, that will probably be the best you can get.
    Personally, I think it looks good. Very CG like to my eyes.

    If the game doesn't scale UI with resolution> You can always do slight downsample+SGSSAA (IE. 1.2x1.2 downsampling) and maybe add a little sharpening if the blur is an issue for the individual.

    Thanks for updating though. I know trying to manage through work and life to get it done can be a chore.

    Very nice comparisons Canzah :)
    I just picked up the Digital Deluxe edition of Alien Isolation yesterday.

    I'm simply using 3840x2400 downsampled to 1920x1200 and FXAA in AI.
    SMAA T1X once again barely eliminates any temporal aliasing, and unfortunately SMAA T2X is unavailable to SLI users :(
    And thank god you can disable Chromatic Aberration and Film Grain using simply ingame settings :)

    Btw I don't recommend setting the ingame vertical FOV higher than 55, since this can cause your characters body to disappear when looking down.

    EDIT:

    I wrote a small SLI/tweaking guide for Alien: Isolation, which explains these aspects in more detail:

    So, the original Sleeping Dogs , I have it. Never played it. Was it DX11 only?

    Oh well you aren't missing much. SMAA T2x is pretty unimpressive in every example i've seen it used and in my own testing with Dead Rising 3 and Crysis 3.

    Yes, SD is DX11-only :)

    Sleeping dogs works on dx 10 cards as well.

    "0x200002C1" works very well for SGSSAA in this game, but is limited to 16:9 resolutions.
    I have found no other combinations of AA bits, that work in non 16:9 aspect ratios.
    This is the same with "The Wolf Among Us" and the "0x204002C1" AA flag.

    Crysis and Crysis: Warhead are some more examples of where the AA fix actually hurts SGSSAA quality (0x000002C1).

    Done. :) It was a rather large image.
