Providing support for an unknown feature set that (possibly) directly competes with an in house developed first to market known product does not make Nvidia more competitive. What it does do is lend value to that competing feature set that appears to only be supported by Nvidias only direct competitor in the space.
This is not good business and it will not be good business unless freesync becomes the defacto implementation.
And regardless of your statement all indications are active sync was developed by AMD and gifted to VESA (likely on an effort to undermine an existing similar implementation created by a competitor - which is good business!) This makes it AMDs standard by virtue of creation and by virtue of being the only graphics manufacturer who is actually utilizing the process.
I really don't even know what to make of this mess.
Let's make this clear, adaptive sync, being a part of the DP spec means any VESA member can get access to the info. It is in no way unknown to IHVs. What is unknown is how freesync, AMD's support for adaptive sync, functions. Nvidia does NOT have to follow AMD's implementation, they can (and in any case, will) come up with their own implementation to support adaptive sync.
What isn't good business is giving your main competitor an exclusive feature by failing to support third party monitors. When adaptive sync monitors launch AMD cards are going to have incentive added against Nvidia cards exactly like what happened when G-sync monitors launched.
"Active sync"? Please, if you don't know something, keep your mouth shut.
Adaptive-Sync is a proven and widely adopted technology. The technology has been a standard component of VESAs embedded DisplayPort (eDP) specification since its initial rollout in 2009. As a result, Adaptive-Sync technology is already incorporated into many of the building block components for displays that rely on eDP for internal video signaling. Newly introduced to the DisplayPort 1.2a specification for external displays, this technology is now formally known as DisplayPort Adaptive-Sync.
By nature of being a VESA spec, any member should be able to view and use the technology as they see fit.
This means that it is in fact not AMD's standard, at all or in any way, since VESA is the one in control of its design, implementation (in DP), and ultimately usage. Nor is AMD the one implementing the feature, that's the monitor manufacturers. AMD is providing a feature that makes use of adaptive sync. Nvidia supporting it as well in no way gives AMD an advantage, in fact failing to support it provides AMD with an advantage by handing them an exclusive feature.
