NEWARK, CA (12 May 2014) – The Video Electronics Standards Association (VESA®) today announced the addition of ‘Adaptive-Sync’ to its popular DisplayPort™ 1.2a video interface standard. This technology delivers several important capabilities to computer users: Adaptive-Sync provides smoother, tear-free images for gaming and judder-free video playback. It also significantly reduces power consumption for static desktop content and low frame rate video.
Read more here

BSN also reported the announcement as well as a Q/A with AMD on Adaptive-Sync and Project Free-Sync.

VESA finally accepted AMD's change request and finalized the standard.

Excellent. Now the question still remains - is this solution still inferor to G-Sync with it's high performance processer and framebuffer, e.g. will it have more input lag or not operate as smoothly as G-sync?
 
In before the Nvidia guys come in and say how bad this is. Open source is nice, even if it's not perfect it forces the competition to work harder.
 
For ppl who can't read articles past the op or click links

"eliminate visual artifacts that many gamers are especially sensitive to: screen tearing, input lag, and stuttering."

We won't know until this actually exists, but it will probably have lag and other issues relying on software/drivers.

This won't be a replacement for G-sync, but maybe it will be better than nothing. It could be a year or 2 before we see it though.

I love how you put down a new Vesa standard thats not G-Sync.

It's too bad its a new standard, now Nvidia has to follow the leader LOL

I don't know why I'm bothering to reply to you, but:

AMD's Q&A said:
Monitor vendors are now integrating the DisplayPort™ Adaptive-Sync specification and productizing compatible displays. AMD is working closely with these vendors to bring products to market, and we expect compatible monitors within 6-12 months.

Why are you poo-pooing a new video standard?

Initially it may be. But there's nothing stopping a video card manufacturer from making a module that can handle all of the Adaptive Sync on its own. Kind of like how AMD's audio DSP can handle audio. Now that it's a standard, we can actually have open competition over whose implementation is better. Kind of like how video card manufacturers compete over who can perform the best with Microsoft DX or Open GL API's.

Because It wasn't Nvidia's G-sync.

Anything to do with AMD Prime1 is totally against. Even if its better then anything out there he will try to swing it in Nvidias favor.

There is no way you can try to have a proper argument with him because of it.

I am shocked he hasn't said that Titan Z was worth the $3000 even if it was slower then AMD's offering.

That is just Prime1, been doing it for many years on this forum and Anandtech/techreport/overclock.net etc etc.

So mediocrity is a good thing because it works for "most people?" Not saying Adaptive Sync is going to be mediocre, just pointing out that people with opinions on both sides are equally as ridiculous in their arguments.

I will be interested to see if there are any performance differences between this and NVIDIA's hardware implementation. But this won't stop me from buying the PG278Q when it (hopefully) comes out next month.

Ummm... You do realize Nvidia had to support G-Sync in their drivers...

The Adaptive-Sync compatibility is old news to manufacturers, they simply need to do a little work to support external displays and get it certified. Will probably be quicker than how long it is taking for us to see G-Sync ASICs.

What? Can you guys stop trying to twist the meaning of my post? I said it can help make the competition improve their design which is a win-win for everyone. I'm fine with G-Sync and with this, I really have no preference there. I just don't understand why anyone would look down on this or try to bash it.

this.

He will marginalize anything AMD does that might make itself more attractive.

There are a lot of AMD marketing people here who will attack anyone who tries to discuss both sides of the issue.

They spread a lot of misinformation (read the Mantle threads) and will personally attack anyone who is not selling their product (see above).
 
I think having a set standard is beneficial to both companies and consumers. They don't need to worry about if this supports this/that. There will be less market segmentation. Bluray and hd DVD is a good example.
 
You're infamous for spreading anti amd and pro nvidia any chance you get (one just needs to scroll up to see this proven). I hope you are getting paid to do this because you are relentless. If you like g-sync then this is good news. It won't be proprietary tech anymore because of this new standard. They don't have to spend more time/money promoting it.

No, I'll interpret. He knew the usual bunch would be in here to deride this thing because AMD pushed for it to happen. He also openly admits that like anything that's fresh out of the oven, there will be some growing pains. It happens. But the fact that it's a standard and open means that we may see some truly remarkable implementations of it. I think you're misinterpreting his post a little to the extreme. Nowhere in his post did he applaud mediocrity. It's more like "I know that it may not be as good out of the gate, but because it's a standard, there's no one to hold back innovation on implementing a truly remarkable display. Nor are we now locked into one vendor." At least that's what I read.

Also, this thread can probably be moved to the Displays subforum, where people don't get into the whole Nvidia vs AMD bullshit.

FUD. Name names or don't say it.
 
Glad to hear this news. I like the idea of being able to having this feature without having to buy a specific monitor with specialized hardware integrated (ala G-Sync). This way anyone can just buy a regular DP 1.2a monitor and have the functionality supported without the inevitable upcharge or limited models, or locking themselves into a specific "ecosystem" (which often seems to be nV's goal)

And before somebody accuses me of being a paid AMD shill based on my name, I've been using this handle since before AMD bought ATI ;)

Funny, you fit this very example inside the Nvidia camp more than anyone on this forum...

But this isn't AMDs product any-more.

It is a standard, everyone has access to it.

How is this so hard for you to understand?
 
Nvidia fanboys sent packing

haha.gif
 
doubtful, hes probably just thinking of another way the marginalize the tech.

He always comes back.
 
How does freesync/gsync work when the framerate is above the refresh rate of the monitor? The way I understand it is it syncs the monitor's refresh rate to your framerate, so if you're getting 35fps you monitor will be refreshing 35 times per second. But if you go above 60 wouldn't that cause issues?
 
Displays still have a maximum refresh rate. They update non-isochronously when they can.

I wonder which will come first: the G-Sync displays announced months ago which have not yet shipped, another batch of G-Sync modules for the Asus which have been unavailable for weeks (months?) or displays integrating the new standard.

All of these products are vapor as far as I'm concerned.
 
... and no communication overhead. The last point is particularly important from a performance perspective, as Project FreeSync does not need to poll or wait on the display in order to determine when it’s safe to send the next frame to the monitor. Project FreeSync uses DisplayPort Adaptive-Sync protocols to pre-negotiate supported min/max refresh rates during plug’n’play, which means frame presentation to the user will never be delayed or impaired by time-consuming two-way handshakes.

Good interview thanks!

While comparing FreeSync to the proprietary g-sync this bit caught my attention, less overhead!

Yeah, Dave mentioned that at B3d the other day.

Actually, G-Sync has a small performance penalty (read the Anand or Toms review, IIRC). Adaptive Sync doesn't necessarily have that same issue.

While also correcting a common misconception due to forum BS.

The problem with Adaptive Vsync, as I understand it, is that the GPU has to guess in advance how long it will take to render a frame, and set the VBLANK interval appropriately.
Adaptive sync does not do this.

Oh crap, an Nvidia proprietary, paid-for product has a performance penalty compared to the free, open-standard solution pioneered by AMD!?

I hear the sound of millions of Nvidia fanboys taking positions for their final stand... Loading their 'denial cannons' and FUD bombs...
