    Phoronix: Intel's OSPray 2.0 Ray-Tracing Engine Released

    An area where Intel continues striking with rhythm and near perfection is on the open-source software front with their countless speedy and useful open-source innovations that often go unmatched as well as timely hardware support. Out this weekend is their OSPray 2.0 release for this damn impressive ray-tracing engine...

        I'm curious about this, too. I followed the link to the osprey website and looked at some of the imags in their gallery. That led me to https://pcon-planner.com/en/ which is some kind of interior layout software. I happend to be planning on doing some work in my basement to build it out a bit and I've needed something like this. Being able to make photo-realistic images to share with the spouse will be very useful.

        But, the machine I intend to do this on is an AMD Ryzen 3700X. Given their history of sabatoging performance on AMD chips, I was pretty skeptical of this. I look forward to Michael's testing results. Thank you in advance, Michael, and for providing us a good place to have respectful, thoughtful, and productive technical discussions.

          I'm not too certain about Ryzen 2 and 3, but optimizing for Ryzen 1 is almost exactly like optimizing for Haswell. In fact when using a Ryzen 1, GCC produces slightly faster binaries with -march=haswell than -march=znver1. So I don't think there's much Intel could do at this point without filtering by manufacturer and there is already case law established to prevent that from happening again.

            Can we stop talking about that other thread and talk about OSPray or Intel for once?

                What is so impressing about OSPrey?
                When I looked at the renderings on the website it looks like absolute shit.

                  Unfortunately a rather big issue crept into OSPray 2.0.0 release builds (unintentionally requiring the Intel compiler libraries to run the binaries), so won't have benchmarks until OSPray 2.0.1
