Again, yes. D-u-h.You are simply buying into the branding, and ignoring the fact that every monitor marked as "Gsync Compatible" is using VESA Adaptive Sync or HDMI-VRR under the hood.
If Nvidia calls it G-Sync, then that's what it is - regardless of the iteration used.
I don't get why thats a hard concept to swallow. Actually, I'll just ignore further posts as you obviously don't get it.
