AMD FreeSync LCD displays to be available in 2015
AMD's Richard Huddy shares word that the first LCD displays that will support FreeSync will sample next month with retail availability in early 2015. Multiple vendors are said to be incorporating the technology.
"Multiple" vendors are preparing displays based on the technology, though Huddy declined to name names. Interestingly, he suggested there's more excitement surrounding adaptive refresh mojo than there is for 4K resolutions. You'll certainly need a lot less graphics horsepower exploit the benefits of a dynamic refresh rate than you will to run games at 4K.
Huddy expects entry-level models to start at 24Hz, which is the most desirable update frequency for typical video. Higher-end implementations could scale up to 144Hz and beyond.
Similar to G-Sync, AMD FreeSync will get rid of screen tearing and tiny sync stuttering/pulsing. The protocol FreeSync / Adaptive Sync will be embedded into DisplayPort 1.2a and eDP (embedded Displayport), there is a catch though, manufacturers of monitors are free to decide wether or not to support the technology. At Computex there are supported monitors on display, AMD however will not reveal the manufacturers just yet. The Video Electronics Standards Association (VESA) already announced the addition of 'Adaptive-Sync' to its popular DisplayPort 1.2a video interface standard.

As you guys know AMD announced a competitive and may I say very cheap solution to tackle Nvidia's Gsync recently, it goes under the name FreeSync. The problem thus far is that monitors need to suppor...

Well it was bound to happen sooner rather then later, but Nvidia spoke about AMD FreeSync. The interview is with Tom Petersen who spoke with the guys from techReport. So the credits and everything re...

This isn't an "AMD only" feature. It's part of the DisplayPort 1.2a spec.

ive never had a big problem with nvidia and stuttering but hell anything to make it better is a win especially if it can added for free. glad we have amd or nvidia would gauge us hard.

You mix 2 things:
- Freesync: the AMD technology included in the driver for control the Adaptative sync.
- Adaptative sync: who is the standard included on DP 1.2 (a ) who let the monitor sync to be controlled externally ( by the driver. )
Its clear its not AMD who will develop the Nvidia driver .. Nvidia and Intel will just develop their own driver for include it... And with g-sync, Nvidia have nearly all the work done for take use of adapative sync. ( i suspect their add-in card, outside store the frame in the memory packed, is basically doing what the Display port standard is doing )
I will not be surprised to see Nvidia moving from their actual G-sync scaler card replacement system to a global G-sync system for every Nvidia GPU ( at least for the latest and future generation. )
But i can imagine G-sync + adaptative sync will be available on some specifc model first. Models with the scalers who have been updated to DP 1.2a.
When the DP 1.3-4 will become the connectors used on both GPU output and replace the actual DP on monitors, you should get adaptative sync possible in every monitor of the market who have a Display Port connection. And with new models for 4K etc this could be really quick.
Lets not forget, adapative sync is bringing a range of vertical state from 24hz to 144hz ( and higher ).. G-sync dont work under 30hz / 33.3ms in his actual state, it is so absolutely not usable for real 24 i/s movies... and you can imagine that at this moment, even for peoples who dont care about gaming, this could be helpfull.
On the end of the day, this is a little bit like eyefinity, surround... It should end as a standard feature on monitors.. Maybe some brand will add things on it ( lightstrobe etc ) for differentiate them, or who know what in future, but i see really it as a feature who can be completely normal in some years.

wow not one person yelling lies lies like other forums lol
I will never lock my self into a nv monitor , if I have to pay a nv tax or not.
I too hope this comes standard on all monitors.
-also if amd has hardware on die for this feature , you then have to wonder if on paper/designed into the r9 xxx so they would of had this 3 years ago and did not come out with it after nv came out with gsync imo.

From what I saw vblank is supported by nv too for some time now, at least in openGL.
The __GL_SYNC_TO_VBLANK (boolean) environment variable can be used to control whether swaps are synchronized to a display device's vertical refresh.
Setting __GL_SYNC_TO_VBLANK=0 allows glXSwapBuffers to swap without waiting for vblank.
Setting __GL_SYNC_TO_VBLANK=1 forces glXSwapBuffers to synchronize with the vertical blanking period. This is the default behavior.
When sync to vblank is enabled with TwinView, OpenGL can only sync to one of the display devices; this may cause tearing corruption on the display device to which OpenGL is not syncing. You can use the environment variable __GL_SYNC_DISPLAY_DEVICE to specify to which display device OpenGL should sync. You should set this environment variable to the name of a display device; for example "CRT-1". Look for the line "Connected display device(s):" in your X log file for a list of the display devices present and their names. You may also find it useful to review Chapter 12, Configuring Multiple Display Devices on One X Screen "Configuring Twinview" and the section on Ensuring Identical Mode Timings in Chapter 19, Programming Modes.

edit:
Ah ok, guess we will see soon. And what kind of monitors, if its more TN then no tnx.
I think g-sync is great too, but Im not very fond of that extra price premium and its HW which atm looks kinda buggy - seems to be driver depended.
To be honest I thought its just plug and play, not that it can conflict with some games and cause visual glitches. That's why I kinda find this freesync more interesting, no extra hw, it uses gpu vblank to manipulate with vsync refresh rate..
