@Gue1: I'm just posting what the dev said.. According to him, DX12 would boost the performance of his game (Project Cars) on Xbox One by 30-40%
This, THE BOLD, was never said lol.
The only reference he made was about "his game" "Direct X 12" and a "30% - 40%" increase.
Users were actually trying to get him to confirm that this was for xbox one but the Dev got ghost and never answered it because he knew the game was going to be 900p for xbox one.

Hi Ian, is this 30-40% only PC or this % will be possible on X1 too? Do you expect similar % of benefits using Dx12 on X1?. In other words, about your point of view and your experience, ¿Could Dx12 on X1 a 30-40% boost?
And If X1 architecture is prepared to use efficiently tiled resources, Will be possible to see this technique in Project Cars 2?

DX12 doesn't 'add' power, it improves efficiency and the working environment.On Xbox One API improvements have been ongoing, on PC not so much, hence PC will see larger improvements.
John Hable, formerly of Naughty Dog, eloquently explains the situation in the article linked below. Many PC titles are CPU limited, so will see the 30%-40% gains referenced earlier. On the console side of the equation the GPU is more often the limiting factor, so gains with be negligible beyond standard efficiency gains.
Unfortunately some on social media and the more dubious sites aren't interested in the nitty, gritty details. I've already seen people simplistically stating "we'll get 40% from DX12, 20% from improved ESRAM performance etc", and before you know it they'd have you believe these consoles are as powerful as top of the line PC's!

I'd be interested to hear from Ian what he thinks of the potential of GPGPU compute. I've seen a number of presentations where this is proclaimed to be the next big leap forward for console development. Is it something we could see utilised in Pcars 2, or will these be reserved for 1st party titles, without the complications of multi-platform development.

Well, he is the first developer working on a Xbox One game that has put a number on the performance improvement brought by DX12. This is world exclusive news. I think it's sensible to ask for confirmation.

The 'number' is related to specific areas, bottlenecks exist in other areas, ie the GPU's ability to shade more triangles.
Basically PC's are more CPU bottlenecked, so will benefit greatly from DX12, consoles are more limited on the GPU side.
Two articles explain it here.
