The visuals are a big draw for this game for me, too. I'll be happy with ultra settings if I can't have ray-tracing. From what I understand you can use ray-tracing on the 6800, but anything over 1080p will drop your fps to less than 30. Maybe by next December I'll actually be able to find a 3080.I'm pretty sure that the Radeon 6800 will be able to do Raytracing at 1440p in the future, similar to a RTX 3070 (DLSS disabled) and at least as good as a RTX 2080 (DLSS disabled) in newer titles.
Since Cyberpunk is sponsored by NVIDIA, it's possible that CDPR is not allowed to put names of AMD cards inside those green-lighted columns. Another simple reason could be that AMD-drivers are not ready yet.
Also, all the next gen consoles feature AMD graphics, so although RT looks outstanding from what we've seen so far, it just can't be that important for the game experience.
