Support all the the features on showcase today, doesn't equate to support full feature set. Two very different statements.

I’m pretty sure Cerny mentioned Primitive Shader and not Mesh.

That would also explain why third party's are raving about the ps5 development tools calling it the best there has ever been. 

I'm gona agree with redgamingtech here and say that ps5 is more custom and Xbox is more of the shelf.  And it would make sense as ms wants to blend their console market with the pc. So it would be beneficial for it to be as close as possible. 

Same thing :)

Godfall is on PC as well.

Will be interesting to see how Godfall on ps5 compares to Pc and whether difference in tech the AMd/microsoft colloborated with will result in advantages to the pc version, or if it's too early to see games to take on the full set of advantages. 

It would only matter if PS5 had all the RDNA 2 features and Xbox Series X was missing features.

You might be correct in saying that the PS5 might have features of their own not included in RDNA2, but it is not Microsoft's job (nor interest) to talk about that. They are only interested in letting people know that their console has the full RDNA2 set of features.

As to which are the features pertaining to X series? This Anandtech article about RDNA2 might give us some clues:

"AMD has previously disclosed that RDNA2 would be a DX12 Ultimate-level architecture..
Overall, DirectX 12 Ultimate focuses on 4 major features (and some minor spec changes): Ray tracing, tier 2 variable-rate shading, mesh shaders, and sampler feedback."

"Finally, AMD today is also confirming that they will offer support for Microsoft's DirecStorage API. Derived from tech going into the next-gen consoles, DirectStorage will allow game assets to be streamed directly from storage to GPUs, with the GPUs decompressing assets on their own. This bypasses the CPU, which under the current paradigm has to do the decompression and then send those decompressed assets to the GPU."

I think it would have been a major talking point, had Cerny not spent the majority of his presentation talking about these exact features.

Seems like a bit of a misleading info that only serves a purpose for teh console warz.

I'm more curious if the DirectML upscaling could actually render games running on the Series S to 4K resolutions without looking choppy. If it can, then it might make the console a much more popular thing, even if some games skip on some features (I'm looking at you Vergil!)
