[HELP] Option for Variable Refresh is gone after installing new graphics card (PowerColor 6750 XT)

EDIT: The audio issue on Wayland seems to have magically resolved itself after several reboots, so while I never figured out why the option for VRR disappeared in the Xorg session, I’ve resorted to using Wayland and everything seems to be as it should.

OP: Howdy. I just installed a new graphics card in my gaming rig, and now the option for Variable Refresh Rate is gone from the Display Settings when I log into a Gnome Xorg session. I swapped out my trusty Vega 64 for a new PowerColor 6750 XT. Before the swap, I always signed into an Xorg session and the option for Variable Refresh Rate was there. After the swap, the option for VRR is there only in Wayland. So why don't I just use Wayland, you ask? The problem is, on Wayland, the audio is distorted and I cannot figure out how to get clear audio. This audio issue seems specific to Steam b/c I can listen to music videos on YouTube crystal clear.

So now I have this dilemma where I have to choose between clear audio (Xorg session) vs variable refresh (Wayland).

Is this a known thing where Xorg doesn't support VRR for newer graphics cards? Is there some trick for getting clear audio in a Wayland session? Do I need a newer kernel or something?

What I've tried so far:

  • I've tried all three DP outs on the new graphics card.
  • Double checked that VRR is toggled on in my monitor's settings, and I can tell if VRR is working or not by turning on the monitor's FPS overlay. I know it was working in Xorg sessions before I swapped out the Vega 64.
  • Updated my motherboard to the latest BIOS.
  • Searched the interwebs for nobara 38 xorg vrr option gone, but alas, not much is coming up.
