    Phoronix: Radeon Vulkan Driver "RADV" Adds KHR_ray_query Support

    Back in Q4 the Mesa 21.3 release added Vulkan ray-tracing support for the RADV driver. That RADV ray-tracing support has continued to mature and see performance optimizations. The latest major achievement for RADV's ray-tracing support is implementing support for the Vulkan KHR_ray_query extension...

    Nice! Time to test if Cyberpunk 2077 works with ray tracing now.

      I hope they will publish their Stadia's Vulkan API too..

        Does Stadia support ray tracing? I thought they are using amdvlk which didn't have it yet.

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

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

                Yes, same with Nvidia.

                  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.

                    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.
