Also Koduri hinted that some desktop monitors might have the necessary support, but Petersen from Nvidia claimed no such ASIC exists, and that they would know if one did. AMD needs a DP 1.3 monitor with the right controller support, and DP 1.3 isn't ready until Q2, and no one knows when and if monitor manufacturers will bring out first DP 1.3 monitors and whether they'll implement the optional dynamic VBLANK capability.

Do not forget that AMDs stuff is reactionary. The real question is whether AMD would have released stuff like FreeSync or FramePacing if it weren't for Nvidia bringing Gsync and FCAT etc.


Neither Nvidia nor AMD are "good". They are just playing the cards that they are dealt. In the end both want to make money, it doesn't matter what mask they are putting on towards the buyers.


Thank you OP, this is a sensible post, I subbed because I wanted to know more about AMD's new development but a lot of posts in this thread is just trash and fanboy talk based on assumptions. It's just not pleasant to read. I just wanted info on freesync and it how it works. But all the offtopic posts and rants are on a level that is just too low. And I can appriciate a GOOD rant.

In short, he admitted that both Free-Sync & G-Sync will give the same result without one being superior to the other.

Come on??? serious? That's what you get out of that article?

I conclude that AMD (hopefully) is on the right track with this tech but have to do more reasearch and work to get it working on desktop monitors because of the scalers.

And I do hope they succeed. My previous card was a HD6950 but it died and I went for a 670 because the price was right (second hand) and no extra delivery cost. I don't mind buying another AMD card when upgrading if it gives me the features that I want.

Won't be possible since it's windowed. How the system treats a windowed process and a full screen is different.

When there are multiple windows, which one takes precedent?

The demo shows that AMD has made something which is already in the Vesa standard useful and not only that but has showed Nvidia up as they require you (currently) to purchase a module or a entirely new monitor. Unless Nvidia had no idea that there was a Vesa standard for controlling Vblank (Unlikely).
It won't work on current desktop monitors.

You can't use it with any existing desktop hardware.

How about a checkbox and a slider in the control panel?

Check box to allow user override of equal priority.
Slider to raise or lower the priority of a particular display.

That way you could have say 90% of your processing power on display 1, and 10% on display 2, and do what I do, and play a game in Windowed Mode on display 1 and have most of the power going there, and just a little bit on display 2 where I run a web browser, MP3 player, etc.

Also I guess monitor sales will go down with 4K on the way, so being a little late won't be that bad for AMD this time around.

Even if AMD's option is cheaper......is it really an apples to apples comparison, or is AMD just creating a passable option.

In performance? Who knows, it's certainly not apples to apples in implementation.

"That said, Nvidia won't enable G-Sync for competing graphics chips because it has invested real time and effort in building a good solution and doesn't intend to "do the work for everyone." If the competition wants to have a similar feature in its products, Petersen said, "They have to do the work. They have to hire the guys to figure it out."

This has to do with GPU-display syncing. You have to sync 100% to something... otherwise, it's pretty much pointless.


Also, splitting resources does not work like that. When you are talking about "processing power", you are talking the aggregate of dozens of steps in a pipeline. Each application has different bottlenecks in the pipeline so you can't grossly assign resources without possible large inefficiencies.

Can you share info from the article on how you came to that conclusion?

I wouldn't go so far as saying that. I imagine that if the panel (not the dvi scaler in the monitor) has a eDP receiver that supports PSR, then you'd have a good shot at getting it to work. You'd have to open your monitor up to find out, and you'd have to be lucky that the monitor uses the same receiver chip as a laptop panel (think small resolutions). I would be willing to wager that there are a rare few desktop models floating around that support it.
post #300 of 388

If laptops already use it a decent chunk of monitors, even if they are laptop monitors, that would make it much easier to get freesync into desktop monitors. I doubt more than a handful of OCNers (if that) could explain the difference between the workings of the two, so as to their comparative costs/ease of implementation/effectiveness, that is still out to the jury.

 

But please, there is no reason to think G-sync is better because it costs more. As of now, it's only true benefit over "freesync" is that it is possible to buy now, and likely be the only option for a while yet.

 

What makes me excited about freesync is that the presumably low cost and implementation into existing/upcoming standards is that makes it much more likely to turn up in 4K IPS panels - and Oculus Rift.
