NVIDIA To support VESA Adaptive-Sync Technology, GSYNC Compatible
It has been a topic of long discussion but in a short and a bit of a confusing explanation, NVIDIA seems to be making a move to support adaptive sync (aka FreeSync). The feature will be enabled in future drivers, however, will only work on selected monitors.
From the looks of the monitors that are going to be supported need to be tested by NVIDIA and thus certified by NVIDIA. We're sure that is a partner certification program that needs to be paid for by the monitor manufacturers to get that new 'GSYNC Compatible' logo. So in one way or another, that might invoke a price premium. According to Nvidia this works on the 10 and 20 series.
Merely (a handful of the current 500+ monitors will be enabled support to Adaptive Sync on GeForce graphics cards. That number should expand over time. Multiple monitors have been tested and certified including monitors from Acer, ASUS, AOC, Agon and BenQ. These will get driver enabled for adaptive sync on January 15th. The certified monitors will be called ' GSYNC Compatible'.
Updated: we reached out to NVIDIA. Not certified monitors will work as well by manually enabling the mode.

Once your FPS drops below your monitor refresh rate, you will see same frame 2 or more times ( called "stutter" ). FastSync is basically VSync that pulls latest processed frame.
FreeSync or Gsync adjust monitor refresh rate to GPU, so you don't see same frame twice and as GPU done rendering new frame, it will be shown on the panel.
So FreeSync or Gsync shines if you FPS drops below your panel refresh rate, otherwise, it's not that great.
Advanced users adjust game settings, so they have stable fps above panel refreshrate and cap FPS with software to match refreshrate, without relying on Vsync or other solutions.
I don't get why people care about Adaptive sync on monitors. Nvidia Fast sync or setting the window mode on borderless completely eliminates tearing or stuttering without requiring any specific hardware. can someone explain to me why adaptive sync is needed?

I don't think it has much to do with them. I'd say it's much more to do with all the gripping over the internet these last few years. All of it warranted mind you.
Thanks AMD. You are the best.

Nobody ask if frame doubling work when game fps is below VRR range?
Cause in Gsync case, frame doubling/tripling etc is done by the custom Gsync Altera chip in the monitor.
Meanwhile, in AMD Freesync case, frame doubling is done by the GPU. Technical name is Low Framerate Compensation.

This is bad news for AMD. Freesync screens were far more numerous and far cheaper than Gsync screens, despite Nvidia boasting some 70-80% of the gaming video card market. So, there would have been people who liked the AMD side because they could actually afford a screen with adaptive sync. Furthermore, if they already had a Freesync screen, they would be somewhat more likely to stick to AMD. Nvidia's decision to support only their own Gsync this long is because they had such a giant market share and maintaining the strict policy brought them money directly from screen manufacturers who wanted to have Gsync. But practically speaking they were voluntarily limiting themselves out of some potential market, so this move was something that could have happened at any time. Ironically enough this turned the tables because now Nvidia video card owners can use great many more screens, but there's no way for AMD to support existing Gsync screens. But at least Gsync screens will most likely become even more scarce in the future. However, a screen can work for many years.
