Not running, still here. When you ask a legitimate question I'll be happy to discuss it with you. You just keep making the same point that these things aren't available yet. We know that. It's not some great revelation. GSync isn't available yet either. We know it will be soon though, and that's good enough. Good enough when it's nVidia, that is. When it's AMD you call it empty PR. That's just a stupid argument that isn't even worth replying to. So keep making your empty points since it seems to be the limit of your ability to discuss anything.

Keep running...it suits you ;)

Actually I don't think you can get G-Sync right now as all the kits and monitors are sold out (falcon northwest and maingear might still have some, but there you have to buy an entire system to get one), there should be another batch in a week or so however.

You can buy the kits from nVidia.com.

Also to put it mildly it's a bit hyperbolic to call something that was announced 5 days and not as an actual product, vaporware.
If you're not able to show something then it is vaporware. They could have even used powerpoint slides. There would be no difference in the outcome.

The question isn't really how many OEMs make a statement of supporting freesync, the question is how many of them make a statement of (fully) supporting DisplayPort 1.3.
Why? DP 1.3 is not fixing any problems with VBLANK.
Look up the eDP specifications. You will see that eDP is using VBLANK - which is a standard feature of the current DP protocoll - for starting PSR.

If you use the term "variable VBLANK" you will find nothing with Google. With makes sense because something like this doesn't exist.

Yeah, I see where you are going to be able to buy them for $500 or have one installed on an existing monitor for $300, or the kit alone and do it yourself for $200. I assume Asus isn't going to be willing to warranty these modded monitors though?

Most monitors have a one year warranty anyway. How old to you believe this particular ASUS model is?

Next problem 3D.

Is it? That's good. All I saw was pre order. Which is fine. It's not like their was any doubt that it was coming. I'm sure FreeSync, or whatever it ends up being called, will happen too.

Looks like we'll just have to keep knocking down your false claims, one by one.
Hey, that's what these forums are for, right? :)

I think freesync is a combination of drrs and psr. The combination allows genuine refresh rate changes but not quite the same thing as nvidia because the GPU is telling the monitor its refresh rate rather than when to refresh. It wounds like a subtle difference but its really not, its going to make quite a big difference in practice to gamers as in theory it will produce uneven latency (and have more latency, a lot more).

Its not quite vapourware but AMDs purpose was to try and get monitor makers to add seamless drrs and psr into desktop monitors when implementing do 1.3 displays, maybe even to get it into the spec rather than it being optional. But it's far from a product launch, it was a basic capability demo and not really something targeted at customers.

It's this one. Brand new model that you can/would buy today, with a 3 year warranty. I'm not sure what you are trying to say? You think it's only for old out of warranty Monitors?

It's called making a mistake, and then realizing it and saying so. I can understand why that would be difficult for you to understand and see it as gloat worthy. Feel free though to correct me when I make mistakes. That's how we all learn. Try to keep the rhetoric down to a dull roar though, OK! It's petty.

Edit: Which, BTW, it is $300 to get one with the G-sync module pre installed and they are currently pre order. So, what I said technically wasn't incorrect. Just that you can buy the module for $200, so you could in theory you can have this setup for +$200. It's still too much, IMO. I'm wondering if people who have bought a 144Hz monitor really are interested in adding a module to it so it performs smoothly at less than 1/2 it's refresh rate. Doesn't really add up. At least from 120Hz gamers I've seen post on these forums who don't buy their monitors to play at 45fps. Which seems to be the target speed that's used to show G-sync at it's best (when vsync is at it's worse).

I think, that unless you already own this particular monitor, than you shouldn't go out of your way to buy one just for the sake up upgrading it with G-Sync. Otherwise just wait for the already built in G-Sync monitors. Don't you agree?
But anyway, all this talk about G-Sync, and this is a Free-Sync thread. Unless you folks feel it's right on topic? Because the two "technologies" couldn't be more different.

If you ask me Nvidia was out of their mind to release Gsync right now on 1080p TN panels.

They are sabotaging their own sales because I would imagine most gamers like me are married to a monitor for YEARS at a time. With the 4K onslaught incoming I think you would be nuts to buy 1080p anything right now. I think if the unveiling coincided with 4K going mainstream many would have gotten on board to get that resolution upgrade.

I'll be waiting for reviews on various 4k gsync monitors, freesync news, and reviews of 20nm GPU's before I decide anything about monitor and GPU upgrades.

A lot of people will still buy 1080p. All the polls on this site still show the vast majority are using 1080p, even if though there is a vocal minority that says otherwise.

That said, they have announced a few 1440p and even showing 4k monitors that will be available in spring and later. I don't see a problem.

I too am likely to go 1440p, but I want a 3D monitor, so I'm not certain those will be available or not.

That's the thing, most of us are using 1080p. Why upgrade to crap TN 1080p? Very little reason to.

If you use the term "variable VBLANK" you will find nothing with Google. With makes sense because something like this doesn't exist.

Who said there was any problems with VBLANK?. what we need is variable/dynamic/adaptive/whatever VBLANK, which is already present in eDP in the form of seamless dynamic refresh rate switching. Apparently this is coming to DP in version 1.3

eDP does not "use" VBLANK to start PSR as such, eDP uses a self-refresh entry sent using a secondary data packet, which is sent during the VBLANK interval, but again I don't know why people keep talking about PSR unless you know something I don't know, as I can't see how it is relevant to freesync.

Also if you type "variable VBLANK" in to Google, you will most definitely find something, namely the anandtech article on freesync ;)

I'll be waiting for reviews on various 4k gsync monitors, freesync news, and reviews of 20nm GPU's before I decide anything about monitor and GPU upgrades.

Also it's more that you're nuts wasting money on gsync for a 1080p monitor. With the glut of GPU power we have now, easily overwhelming 1080, that $200 premium is better sunk into more GPU power letting you run high FPS at 1080p never seeing sub 60fps.

So many gsync reviews said it mainly shines at sub 60fps and shows the most impact there, between 30 and 60fps. It seems suited for making setups that can't manage 60fps minimums feel better. Only makes sense to me to put it on a 1440p screen or higher and even then 1440p/1600p are tamed with a dual GPU setup of current halo cards. I never go below 60fps in any game at 1600p. 4K is really the best usage case for gsync, a resolution where you can't maintain 60fps with any GPU setup if you are pushing maximum settings.

1440p/1600p/4K in IPS/IGZO panels and gsync is worth getting. 1080p is just pointless with how easy it is to crank frames over 60fps all the them at that resolution with just a single powerful card. There is a reason the demos used to display the tech are running at sub 60fps...

Don't be silly, gsync will be great all the way up to 144fps/hz.

So what you are saying is....we have a glut of GPU power that "overwhelms" 1080p, but people should sink another $200 into the GPU? I'm not following.

The market will decide if it is worth it or not. I can't think of a reason anyone would be against G-sync.

With the 4K onslaught incoming I think you would be nuts to buy 1080p anything right now. I think if the unveiling coincided with 4K going mainstream many would have gotten on board to get that resolution upgrade.

I'll be waiting for reviews on various 4k gsync monitors, freesync news, and reviews of 20nm GPU's before I decide anything about monitor and GPU upgrades.

Most people own $230- 1080p monitors, but there is about to be an onslaught of 4k purchases, because there are a couple sub-$1k 4k monitors?

Free-sync doesnt exist...G-sync reviews are available....and 20nm GPUs are a different market altogether.

Why would I want to upgrade to a crappy IPS monitor?

It's all about perspective. A gamer is going to want high FPS, low motion blur, and ideally no tearing. A 144hz 1080p G-sync monitor would fit the bill.

Now, I won't likely go IPS, but 1440p does sound interesting to me. IPS panels are really bad for active 3D. They are less than good at high hz. I require high hz and like 3D.

Except even if you went two $200 gpus, that's what two 760s and synced 60 fps in every game (unpossible) it still wouldn't be as good of an experience as one 760 with G-Sync.

They buy them mostly because they are cheap. How many $500 1080p monitors do you think are purchased? Also, finally when 1440 starts to get affordable with the Korean models we are back to $800 for a G-sync model, and it's not even IPS.

I honestly think that in the next year or two 4K is going to be fairly ubiquitous. 1-2 years is not a long time in display terms. I usually keep a monitor until it no longer works. If you're waiting 1-2 years for 4k to get cheaper why wouldn't you wait for 4k gsync, freesync news and possibly reviews, and 20 nm gpu's?

Stop thinking I have some hidden agenda and attacking my post. Read what I said instead.

So you believe 760 sli at 1080p is not as good as a single 760 at 1080p with gsync...alrighty then.

Yeah it looks good, but that's getting swept away on nvidia marketing.

Based on V-Sync, MGPU frametime issues, min FPS hardly affected, power consumption, heat, yeah I'd take single 760 with G-Sync over 760 SLI all day everyday and believe I'm getting a better experience too.

Another issue with V-sync, is that it results in 17ms of latency when you are at 60 FPS on a 60hz monitor. If you aren't maintaining your hz in FPS, then you get stutter and latency is erratic. Latency wise, V-sync with 60 FPS on a 60hz monitor, is the same as 30 FPS without V-sync. Granted, it isn't as smooth, but the latency is the same. G-sync doesn't add the latency that V-sync does.

Look man, TN panels are just fine for gaming. Actually better than IPS panels. And that it what we're talking about here. G-Sync/FreeSync whatever sync is for gamers.
Nuff said.
