    It means they can, but they won't do it.
    The guy basically just confirmed despite the "lack of DP 1.2a" certification, they can implement VESA A.S. for Maxwell and Kepler, yet they have "no plan" to do so.
    Technically, maxwell and kepler are 'DP1.2a compatible'.

    I think you're reading too much into it. AMD originally listed the 7000 series as Freesync compatible then pulled it - later they pushed DP1.2a into VESA spec for the 200 series and got flack because some of the rebrands (280x) didn't support it. There's clearly something required about 1.2a hardware to do freesync. If it was just a firmware update or something they would have at least supported it on 280x.

    The original Bonaire HD 7790 (the second generation GCN) before being rebranded as R7 260X did support Freesync and it was released in March 2013.......
    I agree there is certain requirement for 1.2a VESA A.S, but considering GTX 650 Ti BOOST was also released in March 2013........plus all big three gpu makers (including Intel) have access to the DP specification and draft........plus both GPU are capable of VRR........and confirmation from both Nvidia and AMD that their VRR made use of VBlank 'feature'..........am I really reading too much into it?

    AFAIK the 7790 doesn't support Freesync. Bit-Tech reported it did back in the day but other sites were unsure. AMD doesn't list it as compatible and there is a reddit thread of someone not being able to get it working. The R7 260x has DP1.2a and thus supports it.

    Why does it matter who had access and when? The card doesn't physically have 1.2a. Probably because it was an interim release with only one purpose - and Nvidia was already filling that with G-Sync.

    FWIW he further clarifies it here.

    Again, if there was just a firmware update or something then AMD would have done it back with the 280x and whatnot.

    Technically Nvidia able to do it, just do not want to do the job done.

    NVidia clearly holds their own customers in high regard.

    /s

    I don't need the support since I have a g-sync display, but goddammit nvidia. That's borderline contempt for your customers who bought into Team Green, giving them a corporate platitude response. "We don't have plans." Really? You could at least have said "it's not possible, unfortunately." Even if it was a lie, you would not come off as ditching your customers.

    I can imagine Nvidia will consider it an incentive to encourage people to upgrade. In the end Nvidia won't gain anything from a person buying a Freesync screen, but they will from a person buying a new Nvidia video card. While 980Ti is an able card still, in general there are already two newer generations of GPUs from Nvidia, so Maxwell is old. From AMD there's only one new generation after those times, so relatively AMD cards from back then are still fresher, in a manner of speaking (in a stupid manner of speaking).

    Here is the thing. HD 7790 does not support True Audio either. Flash in vBIOS from R7-260X and there it is... ready to serve.

    I like how everyone saying that Nvidia could do it, but offer no proof how, no logical thought about why AMD didn't do it back when freesync launched, nothing. It's just magic, they just magically do it with a leather jacket wand.

    The 7790 is GCN2. Does the same vBIOS update enable Freesync? Why didn't AMD enable Freesync on 280x despite public outcry about it? Like where was the "Technically AMD can do it but they want people to upgrade from 280x's to 290x's!" arguments then?

    Even maxwell in laptops able to do adaptive sync long time ago. Here is the key why and able to do it to the rest of the maxwell users.

    Because eDP has supported variable VBlank prior to DP1.2a becoming a thing? It was used for power savings in laptops for years prior. The regular DP standard never supported it until 1.2a. Strangely every card that supports it happens to be 1.2a or eDP.

    The response was "no plans", not "it's technically not feasible."

    "No plans" translates to "we don't want to" instead of "we can't."

    Maybe he misspoke though. I don't know. But in any event, "no plans" is like a middle finger.

    That is why working nvidia in the back on hdmi support.... or so. They can do it if they want to do it. Simple. So technically able to do it but do not want to.
    Same story as Fermi DX 12 suport. Lot of users said here , no official driver will come out because it is impossible. Guess what, after the pressure of users they have released it.
    Sad part, users just accept what company's saying.

    Read the rest of the thread.

    HDMI specification permits vendor specific addons and has a protocol for enabling them.
