    You can eliminate the black outline around textures for example. I personally think the game looks better without it.

    That worked. We should add that as a sidenote to the AA/HBAO guide since we don't have a "making games look better overall" thread. I don't see anyone finding the grey tone appealing. Not in fable anyway. Sweetfx looks a little better still, however i tweaked the red tone from the ini files, and now it's colorful/neutral. Much nicer. Disabled sweetfx since I'd rather not use it unless I have to. (Performance hit is huge while using DSR)

    What? Nvidia doing more than the bare minimum?

    Like that will happen!
    Because Nvidia didn't even do any of the work. They just took what a community like this did and copypasta it.

    There is a thread that combines pretty much all of it, here

    I did 2520x1575 to 1680x1050 so an exact 1.5x and the result was very good. Yeah, there was shader aliasing in certain scenes with bright lights behind solid metal, but overall it was a drastic improvement.

    Maybe try going for a bit more.

    almost perfect

    but these kind of scenes are where it won't help much.

    World of Warcraft changed their AA in 6.0 and it's not very good with the jaggies. Anyone come up with a way to force AA in it yet?

    With regard to downsampling, you get much better AA if your render resolution is at a factor of 1.5 or 2 of the display resolution rather than 1.25 or 1.75 or something random. So on a 1920x1080 screen, you will get better AA at 2880x1620 than with 3200x1800.

    Well, to be fair, they did the work of developing some pretty sweet GPU's ;)

    Well yeah, that is certainly implied. I meant mostly just regards to this AA and stuff. We are all the ones figuring out what works and whatnot. Their own Flags are only for MSAA 9/10 times. And not very good at that.

    I have mentioned this many times.

    But it's not just 1.5 or 2

    It's any even multiple of your monitor.

    Which is why I recommend people use 3264x1836 for 1080p instead of 3200x1800

    @MR Bonk

    I agree it's silly for nVidia to leave it to the community to find compatible SGSSAA flags for games via trial-and-error. You'd think it would be to their benefit to provide these compatibility bits, as the quality of the effect is so good and would help them to further differentiate their product line.

    As for downsampling, I defer to your expertise on this, though it seems to me that one would achieve superior results at integer and half-integer multiples (i.e. 1.5x, 2x, 3x) just from the way the rendered pixels 'line up' with the displayed pixels. Again though, I confess I am completely n00b.

    For 1920x1080, wouldn't 3840x2160 be the preferred option (i.e. exactly 2x?)

    World of Warcraft - Warlords of Draenor

    The Bit:

    0x000012C1

    Compatibility:

    MSAA
    MSAA + SS - Does work quite well, but some aliasing is still apparent
    MSAA + SGSS (SGSSAA) - Removes almost all aliasing at 4x/8x (duh)
    SSAA - Shadows in game must be turned to Low (same with any Hybrid mode)


    Miscellaneous:

    The full screen glow effect in game causes blurring -- Disable it via the command:
    Code:
    /console ffxGlow 0
    There are currently two things to know about ffxGlow:

    1) It may re-enable itself after changing characters or after reloading the in-game UI (a bug that may be corrected at any time in the future).
    2) Disabling the ffxGlow setting also disables the ffxDeath, ffxNetherWorld, and ffxSpecial effects as well (Blizzard stated it's staying this way for now).

    More information (including some comparisons) in my video - http://youtu.be/jlRTZWKxw-s

    Any ratio that is uses whole decimal (1.10,1.20,1.30,etc)multiples of your display is preferred.

    So 1.20x1.20=1.44 (SSAA) your resolution = 44% more resolution (This is the ratio from 1600x900 to 1920x1080 and why you see the ~40% number thrown around so much when it comes to console games using 1600x900 instead of 1920x1080. )

    1.30x1.30=1.69 SSAA
    1.40x1.40=1.96 SSAA (Closest to a whole 2xSSAA you will get with an even whole ratio without only using one axis over the other)
    1.50x1.50=2.25 SSAA (This is the difference between 720p and 1080p. An even 1.5 per axis)
    1.60x1.60=2.56 SSAA
    1.70x1.70=2.89 SSAA (Closest you'll get to 3xSSAA)
    1.80x1.80=3.24 SSAA
    1.90x1.90=3.61 SSAA
    2.00x2.00=4.00 SSAA (Is 4xSSAA)

    And so on and so forth.

    This makes it easiest.

    Any other ratios introduce rounding.

    an even 3xSSAA isn't actualy even at all.

    The closest whole integer ratio of both axis you can get to this is

    1.732050808...etc

    So the only way to get 3xSSAA without error/rounding is increasing one axis over the other. Same with 2xSSAA.

    Aah, that makes sense, thanks for the 'splaining! It also helps makes sense of why downsampling from 2880x1620 to 1920x1080 works so well, as it also benefits from the 1.5 per axis ratio.

    My 780m doesn't like to push 4K for any modern games, but it will handle '3K' for FFXIII with some goodies on top -- as a 'casual enthusiast', I couldn't be happier :D

    I had to edit my post, but you get the gist.

    I actually don't know what the exact correct terms would be. But the point is we don't want rounding and tons of extra numbers that aren't needed.

    (Hence why X.Y X X.Y always ends up with a numerical result that is X.YY)

    Great video :) ANd yeah, Youtube kills video quality horribly . Representing games and AA over youtube is near pointless because of the compression.

    I wish I knew of good video editing software that doesn't introduce motion blur of it's own (Sony Vegas) for windows.

    Got any recommendations?

    I'd also love to be able to make videos like this, which means I need to buy a new audio interface and mic. which I need to do anyway

    Did anyone manage to play Dead Space 2 with GeDoSaTo? DS1 and DS3 are working just fine. DS2 on the other hand freezes when I move mouse.

    So, VSync is the culprit. Though I have no idea how can be those two things causing freezing.
