No, there's a big gap between "variable refresh is possible within the confines of this standard" and "we have a working implementation of variable refresh" It's possible to implement variable refresh over displayport WITHOUT eDP or adaptive-sync. You just need cooperation between the display manufacturer and gpu manufacturer. That's what NVidia did, using DP 1.2.Adaptive-sync ONLY removes the requirement for direct cooperation between the display manufacturer and the GPU...
When I sayThat was the assumption everyone made at CES, and it's wrong. Those devices implement panel self refresh, and adaptive sync is NOT based on PSR. Adaptive sync is based on a much earlier version of eDP that didn't even mention changing refresh rates. If you don't believe me, check the spec, there's a copy of eDP 1.1 on baidu. This has all been covered before. Repeatedly.
It didn't really recognize a feature, variable refresh wasn't a "feature" until g-sync, it was just something that was possible for display manufacturers to implement, with the cooperation of gpu manufacturers. The VESA standard defined an interface for it, so the people making graphics cards don't have to negotiate a new interface with each different monitor manufacturer that wants to implement variable refresh.
a-sync can be as good as g-sync, that part of the implementation is up to the people making display controllers, not AMD, and if they wanted, they could make it work the same way g-sync does. As for the Freesync side, Robert Hallock is either lying or clueless. AMD does need triple buffering in order to prevent a loss of GPU performance when repeating previous frames. AMD also needs to ignore that third framebuffer when it isn't repeating a frame, in order to avoid excess...
Support for variable refresh from big display manufacturers was inevitable once Nvidia created a market for it(and not a second before). AMD's PR led to unrealistic expectations, you just need to read some of the old CES and Computex threads to see that. If you want a realistic estimate on when we'll see a-sync monitors, assume the chip manufacturers started working on new designs immediately after the g-sync announcement, and ask how long it would take to get those...
AMD owns freesync, VESA owns adaptive-sync. They may be compatible with each other, but they're not the same thing.Adaptive-sync is a set of requirements for DP interfaces and display controllers. Freesync is AMD's implementation of variable refresh GPU hardware/drivers. Freesync requires Adaptive-sync, but Adaptive-sync doesn't necessarily require freesync.
Hopefully we see high refresh rates at 1440p. I'm not sure why the limit is 144hz at 1080p, from the display controller perspective.
Yes, and not quite. DP 1.2a existed before freesync, and adaptive sync was added to the spec. Freesync is still an AMD proprietary term.
Freesync is the proprietary software and hardware AMD uses to drive an adaptive sync display. Intel and Nvidia can't use freesync without AMD's permission, though they can do their own work to support variable refresh through adaptive sync. It might not be an important distinction right now, but these technologies already have enough confusion.
I haven't seen anybody criticize AMD because they were too competitive.
