Yes, and they did in fact do that. We were all theorizing that Nvidia half-assed their VRR implementation by not doing LFC, but they managed to use their entire ass, both lobes.
As for HDMI, you aren’t going to see many TVs with displayport ports, and I want VRR in the living room too. I want VRR everywhere. Even in the bathroom, where I do my poopies.
It’s up to the algorithm in the driver to determine whether to double frames or not. A driver also will have trouble averaging out inconsistent frame times, where a G-Sync module can cope with inconsistent frame times, cause it’s not the driver, it’s the GPU sending refresh rate directly.
NVIDIA Vulkan Beta drivers have been updated to 418.31.03, enabling FreeSync.

Took the chance to install this on my system using a Cinnamon DE, and unfortunately, Cinnamon constantly forcing composition means FreeSync is a no go on Cinnamon. You’ll have to switch to Kwin which has the ability to fully shut off the compositor.
