Haven't tried any native games. Proton works depending on the game. For example Cyperpunk 2077 works but RT in Witcher 3 doesn't yet work (for me).
Compared to Windows? Performance is worse but not by that much (for me on Nvidia). Depending on the game it is comparable. RT is very heavy on performance. You are going to want to enable DLSS or FSR.
From what I've read they both work.
As already mentioned in another post it can be hit or miss. I think it works in most games by now. When Cyberpunk 2077 came out it took a long time for RT to work on Linux. Now it just works on most games I've tried. Witcher 3 being the exception since the update that introduced RT functionality. I'm on Nvidia. AMD should also work now. But supposedly performance isn't great on AMD (just correct me if I'm wrong).
Are you on Wayland? Wondering if rt/dlss works on native games on Wayland or if it just works on x / xwayland
Yes, I'm on Wayland (Sway). I haven't tested any native games. But I think RT/DLSS doesn't care about Wayland or XWayland.
That being said, for now every game you run via Wine/Proton is running on XWayland (if one is on Wayland). They are in the process of merging code for native Wayland to Wine/Proton bit by bit. But it is going to take a while before everything is in place and Wine/Proton doesn't need XWayland anymore. But as I've said, from what I understand this isn't an issue for RT/DLSS at all.
