    Phoronix: Intel Begins Their Open-Source Driver Support For Vulkan Ray-Tracing With Xe HPG

    Intel's open-source developers have begun publishing their patches enabling their "ANV" Vulkan Linux driver to support Vulkan ray-tracing! This is in preparation for next year's Xe HPG graphics card that will feature hardware-accelerated ray-tracing...

    Now that AMD has announced their RX 6000 GPUs with open source Radeon Rays 2.0, also present in the new Xbox and PlayStation, Nvidia has no choice other than to try and forward their closed ray tracing before it becomes obsolete like G-Sync.

    But hey, there will always be people willing to pay two or three or four times as much for the same things, so Nvidia will never go out of business.

      From my reading some of the Vulkan spec, the NVidia ray tracing extension isn't that different from the preliminary Khronos raytracing extension, so I'd expect it to be relatively trivial to port games to the KHR extension. Jason Ekstrand suggested someone write a Vulkan-layer-based translation layer for GSOC.

        Hopefully Intel has a control panel ready to release when its pci-e cards start shipping to end users.

          Huh? AMD's prices are about the same as Nvidia's overall and the performance won't be special. One looks to be definitely better but the other two aren't special in any way lol.

          The way I see it is that AMD alone isn't going to be great though that might spark some lower prices between Nvidia and AMD. However, throw Intel into the mix with similar hardware at the mid and high end and it should get interesting.

          If you want to throw words at Nvidia, words can be thrown at AMD and Intel as well lol. Anti-Nvidia people are funny.

            YESSSSS!!! Intel becomes the definitive solution for graphics!
            Now let's hope that DG2 (or the upcoming high-end desktop card) has ray-tracing support as well...

              Is there anything like softpipe or llvmpipe for Vulkan Raytracing?

                I for one welcome more competition to force prices down, I just hope competition authorities make sure there is no hint of cartelism which has blighted the component industry over the years and other shady practices that force competition out of the market. Is the fine still hurting Intel, it should have been larger.

                  That is not how it works at all. Nvidia supported orginally vendor specific raytracing, but after Vulkan and DXR finalized vendor agnostic version of raytracing, Nvidia started supported it too. So only problem is for games that were written using old vendor specific extension for Nvidia, new games shouldn't be written using that.

                  Also Radeon Rays are not competitor to Vulkan raytracing. Radeon rays are supposed to be competitor of Nvidia Optix, and Radeon Rays 2.0 is equalivent of older Optix stuff that are OpenCL/CUDA based. Radeon Rays 4.0 is closed source similary to Optix and theoreticly is supposed to be utilizing dedicated RT hardware. Problem it is hard to say efficiency of it (optix is implemented at least by Blender by Nvidia devs).

                  Consoles dont' leverage radeon rays or optix. For Xbox it will be DXR (Vulkan competitor), for PS5 i don't know. And here Nvidia supports same DXR that Xbox will be using.

                    Thank you for the detailed information piotrj3. I wasn't aware of the history and intricacies of ray tracing. Do you have any thoughts on the chances of Vulkan prevailing over DXR?.
