Ubuntu 22.04 has ray tracing support for AMD RX 6000 graphics cards, but the performance is terrible. You can install Mesa 23.1 from a PPA and it will work much better. Be sure to take a backup in case something breaks and you need to revert to the stock version. I had some trouble getting the 32 bit Mesa libraries to install, which are required for Steam.
I can run Quake II RTX at 50-60 fps in 1080p on my RX 6700 XT using Mesa 23.1.3 and Linux kernel 5.15.
