gsync/vsync simulation for real life gaming on any monitor??

[bennyrodrigues]

So, it seems like it's now possible to use freesync on nvidia gpus simply by copying the output from the nvidia to the amd in which is connected the freesync monitor.
And that got me thinking.
In that post an example of how gsync works it's shown, in a way that it can be viewed on any monitor.
Can't an application be created with the goal of outputting always, let's say, having a 60 hz monitor, 60 vsynced frames on a secondary gpu in which is connected the said monitor, with these frames mixed together creating the same effect?
Like: GPU 1 is outputting 40 frames > Application takes these 40 frames, mixes them like the example of how gsync works, making a stable 60fps > outputs it to the GPU 2 that outputs it at the said monitor.
Isn't this doable?

It's already done in TVs. It's called motion interpolation. It creates huge amounts of input lag. This is why TVs offer a "game mode" which disables this feature.

So it's not suitable for games.

Yes, the VRR animation at TestUFO -- www.testufo.com/vrr -- is accomplished using an interpolation technique that requires rewriting part of the game engine because of the way the algorithm works. And would also have a bit of lag as RealNC said.

The animations are excellent in explaining to the average laypeople how VRR can smooth stutters, but would require intentional purpose-written apps with this algorithm.
