    Hi@ll, want to share this info:
    it´s the new Nvidia feature,replaces actual vsync;
    it was used before by John Carmack in Rage (under Opengl).
    what it does is to enable vsync when you´re running on 60fps or more,and disables it when its under that rate(59fps and down).
    for me its something like"adaptative Vsync"
    but looks like it is an exclusive feature of the new Kepler nvidia hardware release,
    my question is: is hardware only feature,or it can be enabled via control panel?,so the non Keplers owners can enjoy this...
    figure it out,:3eyes:
    (sorry for my english errors,im learning it)

    Rage is doing it via software so it should work for all cards, since all it does is checking the fps and switching vsync on/off in relation to fps below and beyond the monitors sync rate.
    If it is completely done by dedicated hardware, it will be faster since there won't be the same restriction as polling via software.
    Let's hope that it is hardware.

    And that in Rage made screen tearing, i forced vsync on and i had much better overall experience this way.

    I doubt its gonna be any different here, you can't eliminate tearing even if goes below refresh rate. Ok some game engines have almost none, but its still there. :)

    is for the people who are not total blindos, i.e. they cant live with the tearing,
    but who are also sensitive about the input lag.

    1. vsync-ed tripple bufferd when FPS is bigger than screen refresh(60Hz),

    2. no vsync to maintain low input delay, and smooth frames when under 60fps


    4. is very beatiful feature

    @METAVISOR no one knows what features will be enabled on previous GF.

    Adaptive + TXAA would be nice...

    I'm more interested in nVIDIA's new TXAA anti-aliasing feature, if it's going to provide 16x MSAA quality at the cost of 2x-4x MSAA without any blurred effects then I'm sold on Kepler for that feature alone.

    But we've had all this CSAA and other nonsense in the past and they all proved to be worse than good old MSAA in terms of quality. I'm currently sticking with 8x MSAA + 8x SS, or 4x MSAA + 4x SS in more demanding games but this still cripples performance quite a bit so if we could finally get some improvement in the anti-aliasing department without drop in actual quality I'm all for it!



    Does adaptive vertical sync mean you'll not see the horrid added input lag when you're below your monitors refresh rate? As it is basically disabling vertical sync whenever your below your monitors refresh rate.

    Might be interesting to see how this would work out if you combine FPS limiter with nVIDIAInspector to 118FPS (no input lag on 120Hz monitors with vsync) and this adaptive feature. Might we for the very first time see no performance hit from running vertical sync and at the same time get tearing free gaming without added input lag? Best of all three worlds?

    I read that first it is a kepler only feature and it will be added to 500 series later.

    :thumbup:

    That is exactly what adaptive will be doing.

    Adaptive Vsync is pointless when you have a good card . Double-buffered Vsync will just cause input lag anyway, so the only use for it (Online competitive Games) it's useless anyway.:3eyes:

    There is nothing special about it that is has to be Kepler only feature, its post process AA after all and any modern dx10+ NV gpu is capable of using it.



    Imo if they make it Kepler exclusive then they can go .... them self :p

    Unless its actually FXAA but they decided to call it TXAA for some reason, like in this picture

    Driver 300.65

    Edit: i see it has the same bug like all 29x.xx drivers >> Gamma correction ON.

    TXAA is _not post-processing AA



    TXAA, which we talked about a little earlier, turns out to be a super-efficient temporal anti-aliasing algorithm. It has two levels: TXAA(1), and TXAA2. TXAA1 provides the image quality comparable to 16X MSAA, with the performance-penalty of 2X MSAA; while TXAA2 offers image quality higher than 16X MSAA (unlike anything you've seen), with the performance-penalty of 4X MSAA. Since few games natively support it, you will be able to enable it through the NVIDIA Control Panel, in the application profiles, provided you have a Kepler architecture GPU.

    Ask S†v0r.

    He's the one who created confusion by posting random screenshots and throwing postprocessing AA, i.e. FXAA into TXAA discussion :D

    Yeah. TXAA is really interesting but if there's motion aliasing it's basically useless. I also wonder if it can offer as good subpixel quality than 8xMSAA.

    I didnt create any confusion, i said unless FXAA is TXAA. I didnt say it is :p


    Also how about a source to that TXAA, not some random quote ;)

    Agreed not necessary at all.

    Where is the damn leak of this driver hiding, why is it not here yet :p


    It's in Hardware and no other Series will support it, as they said its a Architecture feature a very interesting one seeing the major spread of PP AA (FXAA,SMAA,DAA) and now 1 new Hardware based again TXAA.

    As far as i know they are for the GTX 680 only (modded inf required), 300.99 drivers are out there too because of 300.65 problems.

    I tried this adaptive v-sync with RAGE but personally I don't find it especially useful. V-sync + triple buffering is far better IMO as there's no screen tearing at all and I've never been able to notice any input lag anyway (I mostly play PC games with an Xbox 360 controller). I guess it's nice to have a new feature though for those that want it.

    How did you try it? Did you get a copy of the new drivers? Post them if you did :p
