Yep, archlinux with gnome 48-testing with experimental features enabled to allow VRR, as well as fractional scaling. I prefer using my 2.8K display at 150%. Appears to be working fine with everything I've used. I have had some issues with wifi cutting out intermittently, but I think that might be a misconfiguration of roaming on my APs kicking the laptop too eagerly.

power-profiles-daemon works well, I didn't like how much the battery drains overnight on the s2idle suspend mode, so I've set up a systemd unit to hibernate after 30 minutes of sleep.
