Which brings back up the issue of the DP 1.2 using Vblank and working with a DP 1.3 device to support FreeSync.....can it work that way?

As of right now it does look like it has to be in DP 1.3 for it to function, his statement was just a semi-educated guess on the matter, which is about all we are doing right now. As of my last righting it was a recognized possibility, it always has been. That possibility being DP 1.2 devices could work for FreeSync...

My, and others, understanding is the final DP 1.3 specification doesn't even have to have it, and it is just one of the options on the table to include in it. Which if it doesn't make it, pretty much kills Freesync before it gets out of the gate.

I swear, that AMD fans are really digging hard on this. Why else would they keep pushing this PR stunt to try to steal the thunder from G-Sync, which IS moving forward and manufacturers are ALREADY making monitors.
The Display Port 1.3 standard isn't controlled my AMD and isn't even FINALIZED. But more importantly, it is just the interconnection between the video card and the monitor ... basicallly the cable between the two. It doesn't magically do everything that is needed. That is why a custom ASIC has to be designed and put into the monitor, which AMD isn't making and relying on the monitor manufacturers to develop and put in. VERY VERY eDP connected panels (ie on laptops can do this ... hence why the demo was done on a laptop ... and NONE of the desktop panels can do this).
Also, since NONE of the AMD or nVidia cards support DP1.3 (because it isn't a finalized standard) ... and DP1.3 isn't the same as eDP ... you will STILL need to buy new hardware. So the whole "FREE Synce" is, just as I said, a PR stunt.
Please merge this thread with all the other "FreeSync" threads. This has been covered already.
Pretty much the point I was trying to get at yesterday, and I know you are simply repeating yourself as well Knuckle.
The only big question on the issue of new hardware is if DP 1.2 devices will work with DP 1.3 for this purpose! We know the cards in our rigs now can utilize VBlank, but the DP 1.2 specification on the interface can not, it is a bottleneck of a sorts.
So, if we connect a DP 1.3 device and cable, will it still work? Even though, technically, the card has a DP 1.2 interface sitting between the card and display itself.
NO ONE HAS BEEN ABLE TO ANSWER THAT QUESTION!
I spent hours online last night looking for a direct answer, and the most direct answer I found was "No". That devices that support DP 1.3 and its features aren't expected to market until end of 2014 or early 2015, because the specification isn't even final.
If this is true, every person sitting with a computer right now would need to purchase a new GPU with DP 1.3 on it to take advantage of FreeSync, even if display manufacturers got on board and started cranking out displays with everything needed to use it.Edited by PostalTwinkie - 1/9/14 at 10:05am
