Found an article I thought would be of general interest here:

http://gamingbolt.com/id-software-dev-puzzled-by-devs-choosing-dx12-over-vulkan-claims-xbox-one-dx12-is-different-than-pc

DX12 on Windows is fairly pointless, but obviously it's the way to go for XBox One. Vulkan on PS4 would make Vulkan a clear winner overall, although it's not clear if that will happen.

It'd say Vulkan on PlayStation would be good for Sony and developers, but they just announced their new console, and showed no sign of any Vulkan support there.

The wish could have been expressed and sorted out better but its clear to me it was made with intention to inform CDPR. Even spelling is wrong. I might make a new one, in games section and with more info if it doesnt get much traction. Im sure if the wish gets enough votes it GOG will inform CDPR.

Ah yes, DOTA!

I just finished reading an article by one of the lead engine designers of id Software's DOOM who said that the DirectX 12 on Windows and the DirectX 12 on Xbox One are two completely different things so the idea that writing for DirectX 12 and automatically getting Windows 10 and Xbox One support in one codebase isn't how it works. I have no idea myself and I assumed they would be the same too, however id Software seems to disagree. Assuming they're right, it takes one more argument away from anyone thinking DX12 is the way to go.

If this is indeed true (and I have no good reason to doubt it), then it's pretty funny because not only can Microsoft not use standard cross platform APIs and have to write their own, but they design interfaces for their own differing platforms with the same name but completely different API. That's funny if true. :)

If DX12 on X1 and PC are significantly different then ill lose more faith in devs.

the problem with these "discussions" over twitter (oh, why do people do this?) is, that there is barely any substance to it. It's just a bunch of thrown away sentences, shortened as much as possible to fit into the character limit.

basically all he says is that for full performance you need a different code path on the XB1.
Given that DX12 (like Vulkan) is
a) all about low level, close to the hardware programming
b) XB1 hardware is different to PC hardware
it doesn't seem that strange that you would use different code to get the maximum out of either hardware, no?

There just isn't very much information in here to talk about actual API differences between PC DX12 and XB1 DX12 that would put up additional road blocks when porting from console to PC.

CryEngine scheduled to get Vulkan support in November:

Good. May be Kingdom Come Deliverance can start using that now. But personally I'm more interested in Star Citizen, and they use forked version of Cry Engine which can't draw from the source anymore, so I wonder when they plan to do that.

I pray Warhorse studios gives Linux edition proper attention, and doesn't cut corners.
For Star Citizen it seems the developers are taking right approach and are delayed because of transition to Vulkan and DX12.
Have you watched this?

Yes, I saw that. It was a while ago, and there was no word about Vulkan and Linux progress in SC since then. Or may be I missed it?

Both games fill the top 2 positions on my "most anticipated" list currently, so if either or both support it that will be very good news indeed that would breathe a little more life into my HD7850 for sure. Hopefully both do pick up Vulkan support for sure though.

I can't find any more news about SC in relation to Vulkan. Deliverance is a game I anticipate as well. Sci fi isn't my cup of tea though but SC is looking sweet.
It's strange that No Man Sky got hyped so much but a game like SC, which is similar genre, and seemingly equal quality fi not better has been ignored.
Must be the gaming "journalism" at play.

No Man's Sky had some high profile visibility in a few places, but I've seen much more info/content/details of Star Citizen over time personally. Most of it on Youtube or via gaming mag links or game conf presentations/demos etc.
