NVIDIA Confirms It Has No Plans to Support Adaptive Sync

During an interview that we streamed live with NVIDIA's Tom Petersen this past Thursday, it was confirmed that NVIDIA is not currently working on, or has any current plans to, add support for the VESA-based and AMD-pushed Adaptive Sync portion of the DisplayPort 1.2a specification. To quote directly:
There is no truth [to that rumor of NVIDIA Adaptive Sync support] and we have made no official comments about Adaptive Sync. One thing I can say is that NVIDIA as a company is 100% dedicated to G-Sync. We are going to continue to invest in G-Sync and it is a way we can make the gaming experience better. We have no need for Adaptive Sync. We have no intention of [implementing it]."
To be clear, the Adaptive Sync part of DP 1.2a and 1.3+ are optional portions of the VESA spec that is not required for future graphics processors or even future display scalar chips. That means that upcoming graphics cards from NVIDIA could still be DisplayPort 1.3 compliant without implementing support for the Adaptive Sync feature. Based on the comments above, I fully expect that to be the case.

With that new information, you can basically assume that the future of variable refresh monitors is going to be divided: one set for users of GeForce cards and one set for users with Radeon cards. (Where Intel falls into this is up in the air.) Clearly that isn't ideal for a completely open ecosystem but NVIDIA has made the point, over and over, that what they have developed with G-Sync is difficult and not at all as simple as could be solved with the blunt instrument that Adaptive Sync is. NVIDIA has a history of producing technologies and then keeping them in-house, focusing on development specifically for GeForce owners and fans. The dream of having a VRR monitor that will run on both vendors GPUs appears to be dead.
When asked about the possibility of seeing future monitors that can support both NVIDIA G-Sync technology as well as Adaptive Sync technology, Petersen stated that while not impossible, he "would not expect to see such a device."
The future of G-Sync is still in development. Petersen stated:
"Don't think that were done. G-Sync is not done. Think of G-Sync as the start of NVIDIA solving the problems for gamers that are related to displays...G-Sync is our first technology that makes games look better on displays. But you can start looking at displays and make a lot of things better."

So now we await for the first round of prototype FreeSync / Adaptive Sync monitors to hit our labs. AMD has put a lot of self-inflicted pressure on itself for this release by making claims, numerous times, that FreeSync will be just as good of an experience as G-Sync, and I am eager to see if they can meet that goal. Despite any ill feelings that some users might have about NVIDIA and some of its policies, it typically does a good job of maintaining a high quality user experience with these custom technologies. AMD will have to prove that what it has developed is on the same level. We should know more about that before we get too much further into fall.
