Not knowing if you're right or wrong doesn't mean you're colorblind. The post itself is neutral, it comments on AMDs side based on what the poster knew, or thought he knew based on what MS and AMD had talked about (and at least not completely wrong based on the quick glimpse I've gotten on these, haven't actually sat down to watch the presentations or read papers on it yet), and for NVIDIA it specificly mentions he has no idea whether there's similar "fast path way" (real or not) or even if there's need for one. It doesn't try to paint one competitor in better light than the other, or vice versa, it doesn't downplay either one either.There is nothing implying anywhere that "DXR 1.0 is deprecated", for AMD or any other vendor, as well as that 1.1 is a "fast path" for AMD RT. 1.1 is an extension of 1.0 with additional options which may provide more efficiency depending on where and how they are used. It's very possible that some h/w will be more efficient doing things through 1.1 in the same place where the other h/w will be more efficient with 1.0 - but it may as be the opposite for the same respective h/w in some other case.
It's basically impossible to say something like what he has said before seeing this h/w in action on your own code.
People need to focus less on who's "supporting" who or what and ignore who's saying something until they've actually read what it is they're saying, focus on the matter at hand, not the persons talking about it.
