    I haven't checked recently but does DLSS and RT work in CP2077 with a NVIDIA card or are there issues there also? It just seems NVIDIA is making more progress in getting RT/DLSS stuff working under Linux while AMD users are stuck with fundamentally borked RT support.
    I'm about 90% certain that AMD's existing raytracing support is IP-encumbered, and they can't release it as is under open source. And they haven't cared enough about it on linux yet to rewrite it in a manner that could be opened up.

    I know. But it isn't Stadia that renders the game, but game. Stadia only grabs framebuffer(or something liek that), encodes and send to client(which sends input back) in simplicity.
    Stadia is that cloud. It consists of the servers containing GPUs and encoding chips (the encoding on the AMD GPU is sh!t) and running the games. The software grabs the framebuffer, encodes it and sends to the user.

    Tested CP2077 - it hangs when enabling ray tracing in it. I assume vkd3d-proton still needs some work.

    it obviously renders everything itself, just on the server, not on the client. So not sure what your point is.

    Michael Sorry to say that, but this small(maybe, because it's so small/downsized) screenshot look like sh^H^H very early OpenGL demo. It's so uninspiring that I would never guess Ray Tracing is involved there.

    WTF?

    You know what's Stadia is? It's like RDP/VNC, kind of remote console(like telnet/ssh) + streaming(youtube).
    It sends to rendering host input, and fetches rendered graphic. Stadia doesn't render anything itself(only encodes video), it's all dependent on game settings and hardware/drivers capabilities on rendering host.
    Client machine grabs input, sends it, and all CPU/GPU intensive work is to decode video.

    Yes, same with Nvidia.

    Thanks for the info about Cyberpunk.
    What about Doom Eternal? Does it work now?
