I'm saying that you like many others have misunderstanding about how such tech works, even if you might see device that claim any VRR/freesync/gsync/etc.. pass thru feature in the future, that's not how such tech is designed to work and that fully kill the purpose of such tech.
VRR/freesync/Gsync/etc... is made to work optimally between SOURCE > DISPLAY directly, there is not any device in the world that, today, can be inserted in between and allow such feature to work optimally and there might never be any.
When working directly source > display, the fps fluctuating range is maximum and optimal based on what source can offer and what display can accept. for ex: min:40 max: 140.
There is some AVR planned in the future with pass thru for such feature, but their range is for ex: 40-80 or 100-140 or even less +/- 10fps, so you effectively go from a 100fps range to 40, 20, 10 or none. > thus this killing the purpose of such tech.
Now to really use such tech as intented and have optimal results there is 3 options:
1) SOURCE > TV DIRECT and you split sound at source level if possible
2) SOURCE > TV DIRECT and you use TV ARC back to AVR for max DD+.
3) SOURCE > TV DIRECT and you use TV EARC back to AVR for up to any audio format. > that is actually the way the industry is going to, TV will soon be the main hub in AV setup and audio system will retrieve full sound via EARC for any connected sources to TV or any TV apps.
That is what HDMI2.1 allows: HDMI2.1 source to HDMI2.1 display works optimally for max fluctuating range and HDMI2.1 display offers eARC to HDMI2.1 AVR.
So to really use VRR/Gsync/Freesync as intended, above 3 are the only correct options.
Sure, you can wait for a device in the future that would claim passthru for such tech, but you will then limit such tech to whatever such device accepts as fluctuating range and may be in a few years they would be good enough to support the worst source and display of today
Except may be our version of it but that's not before end of 2020 at earliest.
If you bought HDMI2.1 TV today without eARC > you are an early adopter and you just get screwed by the industry, like they always screw early adopters.
If you have a pseudo or real HDMI2.1 source with Gsync/VRR/Freesync/etc... and a display that accept such tech but don't have 2.1 and eARC then you are good to get a new TV if you want full audio and you cannot split sound from source AND even if you have a new TV, you still need new AVR for eARC, this is where our devices can help, they will extract eARC from any eARC TV and forward any audio format to any AVR input that support such format.
