    Absolutely worth it to not have to put up with the buggy AMD stuff. I have regretted every single AMD/ATI purchase I have ever made over the last 20 years. I keep thinking, and people keep telling me, "oh, it will be different THIS time". Nope, never.

    Guys, I certainly appreciate all this effort and development. But, tell me, why do I need RT on Vega and Polaris?

    All the other problems have already been solved and now there is free time for this?
    It sounds like it was mostly something fun for him to work on, and it gives him a way to test out ray-tracing apps/tests on older hardware for testing and compatibility purposes.

    I don't want to speak for him, but I guess it is a fun? Not everythink need practical reason :-D

    but not fast

    Obviously that's very much a custom system that probably doesn't map too well to the APIs nvidia defined for their HW-assisted aspects, but it's still a pretty impressive demo of how far you can get just by offloading calcs to the GPU, even without dedicated RT processing cores built into the card itself.
    Wow, nice

    And ye olde i7-3770 with an RX 480 from 2017 came up with 3348 points and around 40 fps on 1920x1080 and "ULTRA RT" - I don't think it's too shabby for a tech demo.

    I now have hope for official raytracing on older cards.

    do you understand that radv is third-party software?

    i guess spirv is designed for (de)serialization, nir is designed for transformation
