From the outset, when g-sync was announced, everything was laid out in terms of plans to market:

Panel vendors.
Release date.
Partners.
Potential cost.
Benefits.
Tech site previews.

In fact you can buy g-sync panels NOW.

Meanwhile AMD has:

Nothing.


What they said:

"We have no plans to product-ize this"
"We don't have a go to market strategy"

If someone doesn't see a difference between this and how g-sync was announced, one would have to be freaking blind. This all goes back to the fact that Nvidia is going to deliver on g-sync. G-sync is about to hit the ground running. Now. Q1 2014. Free-sync? I wouldn't get my hopes up. Sounds like marketing proof of concept and nothing more.

So how does their basically hard launch of gsync have anything to do with what my post said?

You're misquoting and you know it. This is the actual quote:

"AMD’s demo isn’t quite as nice as NVIDIA’s swinging pendulum, and we obviously weren’t able to test anywhere near as many scenarios, but this one is a good starting point. The system on the left is limited to 30 fps given the heavy workload and v-sync being on, while the system on the right is able to vary its frame rate and synchronize presenting each frame to the display's refresh rate. AMD isn’t ready to productize this nor does it have a public go to market strategy, but my guess is we’ll see more panel vendors encouraged to include support for variable VBLANK and perhaps an eventual AMD driver update that enables control over this function."

AMD reportedly said (paraphrase by Anandtech):
- we're not ready to productize it yet
- no public comment on market strategy

You said:
"We have no plans to product-ize this"
"We don't have a go to market strategy"

See the difference? See why people think you're trolling? If you quote something, you need to quote them accurately.

Does it say it doesn't support it in the default EDID or do you simply don't have the line though?

According to this site: http://www.playtool.com/pages/dvicompat/dvi.html*, most monitors built after 2004 should support CVT. Also interestingly it mentions that some older Nvidia cards had problems with their DVI transmitter. This might have something to do with the previously mentioned speculation, about Nvidia cards not supporting the standard, being the reason behind them creating the hardware solution GSYNC.

*I have no idea if the site is accurate or not

There are 7 entries.
ACR0255 [Real-time 0x0011]
ACRO255 [Registry-Active]
ACRO256 [Registry-Active]
GSM5694 [Registry]
NVD0000 [Registry]
NVS0000 [Registry]
SAM0194 [Registry]

All of them specifically state:
CVT standard............. Not supported
GTF standard............. Not supported

Then there are a 5 samples, which also state the same thing.

Guess that largely settles it in your case then, mine has 17 entries (no idea why I have that many):

LEN40B1 [Real-time 0x0041]
LEN40B1 [Real-time 0x0100]
LEN40B1 [Registry-Active]
ACR1501 [Registry]
DELF017 [Registry]
LEN40B1 [Registry]
NEC798D [Registry]
NVD0000 [Registry]
SAM01FF [Registry]
SAM0586 [Registry]
TAA279D [Registry]
ZMT2400 [Registry]
ABC8014 [Sample]
ABCF201 [Sample]
ABC0D1D [Sample]
ABC8114 [Sample]
ABC3D3D [Sample]

Like yours, some of them state:
CVT standard............. Not supported
GTF standard............. Not supported

Some (including all the ones starting with LENxxxx aka. Lenovo) of them only state:
GTF standard............. Not supported

And one of them (one of the [Sample]) doesn't state anything.

Interestingly I also have the NVD0000 like you and mine only says:
GTF standard............. Not supported

PS. GTF is the old standard that was superseded by CVT

I dont know what u guys think but in IMO
Nvidia really i always find a way by Hardware Solution and than AMD try to be competitive with Software Solution

Example
G sycn(nvidia) than AMD(Free sycn)
Nvidia Frame metering(SLI) than AMD frame Pacing (CF with limited features, Res and no DX 9 support)

FreeSync is not a software fix. Frame pacing is off topic so I'll resist commenting, as we have too much off topic discussion already. Suffice it to say you are posting FUD.

It's a software solution.
I guess the driver tries to predict the next few frames and set the display at this Hz.

So it would be only working with a nearly static frame rate.

BTW: nVidia supports variable V-Blank. They uses it for G-Sync:
G-Sync works by manipulating the display’s VBLANK (vertical blanking interval). [...]
he G-Sync module inside the display modifies VBLANK to cause the display to hold the present frame until the GPU is ready to deliver a new one.
With a G-Sync enabled display, when the monitor is done drawing the current frame it waits until the GPU has another one ready for display before starting the next draw process. The delay is controlled purely by playing with the VBLANK interval.

Wrong, HFR say that it s exactly the same thing but you are
free to believe otherwise.

Perhaps in another eight years AMD might have given us freesync other than at a Popsicle stand, perhaps not.

The two techs are fundamentally different, the only thing they have in common is syncing the monitor refresh to the GPU, how is why AMDs solution is pointless as an alternative to G-Sync.

A driver is not enough , actualy it must be implemented
within the GPU engine according to Hardware.fr , it s just
that AMD made the move long ago while it seems that
Nvidia has not implemented it in their hardware, hence
an external solution they call Gsync.

Writing is good enough for google translate to yield
a valuable translation.

In fact you can buy off the shelf products right now which will support FreeSync; that Toshiba laptop is one of them. (Of course, AMD have helpfully not actually told us which devices will support it. Sigh.)

Care to elaborate on how they are different? :confused:

If I understand this correctly, then FreeSync and G-Sync are not the same thing, but the result might (!) be similar.

From an engineering point of view, G-Sync is a lot more refined. When you push a frame, the driver also signals the G-Synv module to "redraw" the screen.

FreeSync on the other hand, seems to play with the frequency so that you can force or delay a redraw if you need/want.

In a best case scenario for both methods, a normal user should not see a difference (no input lag, no tearing). But because of how it's implemented, it should be more difficult to fine-tune FreeSync (GPU-Driver-Screen synchronisation is kinda tricky).

But, this could give nVidia an idea for a future "G-Sync Lite" version, an entry-level version of G-Sync ...

Fundamentally different, except for the fact that they do the same thing? :colbert:
