Read that yesterday
As you can see from my post I was referencing the mobile lineup. VESA Adaptive Sync has been in eDP standards for years.
From the
VESA 1.2a announcement last year
"Adaptive-Sync is a proven and widely adopted technology. The technology has been a standard component of VESA’s 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."
This is how PCPER could magically access
G-SYNC feature without an adaptor using just a driver. Adaptive Sync is already available in many mobile GPU it just needs a driver and a compliant panel.
This is why I said Freesync (hardware free adapative sync) would win the market. How long will Nvidia justify charging a G-SYNC hardware premium to desktop users only; I guess that depends on how many value added features they can enable with their hardware.
