From what I understand everybody will have to buy it. Of course it’s nice to get things for free (especially if they previously stated it would be). But if it’s good DLC rich of content I don’t mind paying. It was the same for me with the two expansion sized DLCs in the Witcher 3.
Yes, RT Overdrive works. But it is VERY heavy on performance. I’ve got a 3080ti and had to sacrifice resolution in addition to turning down DLSS quality to get barely playable frame rates. But yes, it works and looks incredible. Edit: RT Overdrive really isn’t meant for graphics cards which are weaker/older than the upper spectrum of the 4000 GPUs. There is a mod on Nexusmods, which reduces the rays which are being cast. With it you can get a few frames back and you won’t really notice the visual difference unless you know what to look for.
Does the game have to be native or does it work through Proton?
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).
Is the performance comparable? Better? Worse?
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.
Is it only working for AMD? Only for Nvidia? Both? (Neither?)
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).
Yep, thanks for letting us know. On another note: How many of you had the annoying screen flashing on Wayland and had to downgrade anyway? Apparently it happens in Wayland sessions while using a high refresh rate. I’ve had flashing in Sway with Nvidia for a while unless I use a very specific version of sway-git. But this (after upgrading the Nvidia drivers to 535) is way worse.
