I'd also much prefer a IPS 4k panel over a TN. Thing is i can't see it happening anytime soon so my hand will be forced. I can't wait, but im not exactly thrilled about the prospect of a TN.
It's perfectly reasonable to me that a manufacturer would not willingly undertake an action that can result in a rash of product failures, either through user action or an act of God. It's tremendously wise to avoid "exactly the same scenario."
Thanks for the reply, what I did mean though would the 'freesync' element of the driver require an update as new games etc... Come out to allow it to work on these titles or is it universal from the start?
Another question thought of from your reply...does this mean every time a new capable monitor comes out it will require the latest driver to function as a freesync monitor?
I don't know the answer to this question. I'll find out for myself, but I expect that I won't receive an answer for many months until these monitors are close to their production phase.
Can you explain how it works a bit better? Like why only GCN 1.1 Discrete cards will work with adaptive sync but all GCN APU's will?
If the reason is what I think it is, then, were you planning freesync before the release of the GCN 1.1 cards and you added the necessary controllers to the GCN 1.1 cards to work with adaptive sync monitors?

FreeSync is a driver update. It's not profile-based or anything else. Users will be able to turn it on or off in the driver. Driver updates won't be needed with each display, either.

G-Sync latency claims to be equal to V-Sync off (non existent) - Will Freesync be able to match this?
Caporegime
Is there an accurate way to test this?
I guess its possible if you use identical Screens with the exception of one being G-Sync while the other A-Sync, but other than that they do have to be identical as every screen has a different input latency on its own.
Also the systems, right down to the mouse / Keyboard used needs to be identical.
When you have that what do you do then? Record and measure the time between a mouse click resulting in an action on the screen, its a bit crude considering we are dealing with 10's of Millie seconds.

The thing is with 4K and this subject in particular is that with DP1.2 and effectively DP1.2a, you're using all the bandwidth. Hence my question to Robert as if you're looking for 4K, especially in a few months then at 4K I'm not sure how the use of adaptive sync will effect bandwidth. There is already a lot of issues with certain certified cables and non cert ones for this very reason

? Not from what I've seen - the claimed impact was 'minimal' latency increase.
testing examples: http://www.blurbusters.com/gsync/preview2/
not saying it's bad, not at all...
But doesn't appear to be like vsync off.

I agree with you, it would be foolish to think so...overtime as the industry begins to adopt the standard, I'd hope to see more and more displays in the market. The AMD person you're referring to is Raja Koduri, our Corporate Vice President - Visual Computing.

If that was an industry wide stance, being an enthusiast would be boring.
I'll leave it there, but it doesn't wash with me in the slightest.
That's good to know, as we all know latest drivers (regardless of vendor) can have issues that force the users hand to revert back to an older more stable driver for the best experience
I do hope it turns out as good/better then gsync, as the reviews I've read from reviewers and end users alike have nothing but praise for it, sounds like something all pc gamers should benefit from.
The reason is easy (explained here): certain products have newer display controllers. This is the silicon that interfaces with monitors. The 290/260/APUs have this newer IP level, whereas other products do not.
The conception of FreeSync ran roughly parallel to the design of this new display controller IP.

Well I am also watching Tom Peterson on http://www.pcper.com/live/ and that is exactly what he said. Is he telling lies you think? Same question to Sam and Robert
Yes, I understand perfectly and thought this was the case. I just wanted to have somebody from AMD tell me that my thinking was correct
I don't think it uses bandwidth. I was looking up how this works on eDP and it uses Aux channels for control functions, this is not included in the bandwidth of the cable. It's on the VESA website.

The reviews say it's not true, the company that sells it says it is, but in other areas of their own site talk of minimising.... I know which I'll chose to believe. What you believe is up to you. Also, given they normally say 'lowest input lag for a tear-free picture' are you sure he said what you think he said? As that doesn't mean the same as no input lag.
