DirectX 12: The future of it within the console gaming space (specifically the XB1)

[Cyan]

Phil Spencer agrees with the article linked below, and he says that Xbox One games must be written on DirectX 12 to benefit from it.

100% processor utilisation at 100 Watts yields 100 Game Units of Fun

100% utilization on DX11, is it a sarcasm?
Wait, are you talking about CPU utilization?

Well smart move to offer Win7 users a free upgrade (inside year one) to help drive DX12 userbase. Will only help the console, not like where it took years to move people off of XP to start seeing DX10/11 games.

"To get the full support of DX12 will users need to get a new graphics card?"

To get the "full benefits of DX12," Ybarra replied, "the answer is yes."

"There will be DX 11.1 cards that take advantage of a lot of the driver and software tech that we're bringing in Windows 10, but if you want the full benefits of DX12, you're going to need a DX12 card."

We’re more than ready. GPUs built on our Maxwell GPU architecture – such as our recently released GeForce GTX 970 and GeForce GTX 980 – fully support DX12. - See more at: http://blogs.nvidia.com/blog/2015/01/21/windows-10-nvidia-dx12/

they say this with every new DirectX-Generations. They always mean compatibility and not hard-supported features.

The "fully support DX12" does link to their September blog post, though, at which time McMullen himself said that not all features of DX12 are yet public and that there are no tests for hardware manufacturers to confirm 100% feature compatibility yet

So what you're saying is that all NVidia GPUs older than Maxwell will not fully support D3D12.

Just like DX11. (DX9c and DX10 GPUs were supported trough compability layers.
New DX11 features required a new hardware.

I'm not even sure if maxwell supports all directx12 feature set either. It's why I've held off for a while. Until dx12 is released I'm not planning to buy.

Yes, I am glad I caught that slight of wording, because I was getting ready to make a purchase. AMD R9 380x maybe? Edit: Dave don't post anything in this thread if it is fully DX12. LOL

@XboxP3 Hey Phil huge fan. If DX12 requires new hardware for all tweaks to be present how will the X1 have full DX12? Care to elaborate?

@ExploderMouse We knew what DX12 was doing when we built Xbox One.

lol, oh the shade. I suppose under this notion if X1 is full dx12 compliant, it's quite possible that Maxwells should be as well. But I guess that depends on how long they were in development before X1 was released.

Will be interesting to follow. On a side note is there proper english that we can used to denote (in 1 word) the difference between being full DirectX 12 compliant, and fully DirectX12 compatible? If you know what I'm getting at.

That's the big problem - we know that "advertised capabilities" of Maxwell gen 2 surpass those of GCN 1.1, but then what the XB1 guys claim about "knowing what DX12 will be and using GCN1.1 - then there's the fact taht some of Maxwell gen 2 new features are what were advertised as DX12's new features, but at the same time it was said that not all DX12 features are public yet and that there's no compatibility tests for hardware manufacturers yet - it's all a damn big mess at the moment, one saying something, other saying something else and third saying something that contradicts both

edit: excuse the alcohol, I hope you can make out what i was trying to say

If Phil's statement is true then it is kind of funny considering we had people "in the know" telling us that Dx12 wasn't involved at all with the Xbox one's design.
I don't 100% believe though that all of Dx12's added features are fully supported by the Xbox One. Who knows?

What does a CPU need to be DX12 compliant?!

I assumed they were talking about Iris.

It's likely requirements for the integrated GPU in these processors. If you have a discrete GPU you can ignore the above.

Microsoft emphasis on integrated GPU requirements is telling. Discrete GPU marketshare will (sadly) continue to diminish in irrelevance
