I'm using 4070 Ti with open kernel module on Wayland.
It's MOSTLY painless. Some GNOME extensions seem to randomly hang everything on startup (I'm currently investigating which ones, I believe Dash to Dock and/or Unite are to blame) and there's a weird issue with VR when streaming via ALVR: SteamVR launches, but games crash unless I disable the second monitor (no such issues with WiVRn, so not entirely sure if it's a driver problem or not)
Besides that in my daily driving I saw no other issues.
