I can get VRR via Thunderbolt with my gaming PC through a couple of different docks, but it’s flaky. Running a display through TB on that machine is kinda flaky even without VRR enabled, though…
I think it’s either Nvidia drivers or the card itself (3080 Ti FTW3) that is to blame, because the results are the same regardless of the OS I’m booted into (Windows or Linux) and Intel/AMD iGPU-equipped machines have no such problems. It wouldn’t surprise me if the Nvidia driver dev team does little to no testing of TB3/TB4 passthrough with their desktop card drivers.
