Microsoft and partners from Nvidia, AMD, Intel and Qualcomm have officially revealed the next version of DirectX gaming API, DirectX 12, at this year's Game Developers Conference in San Francisco.
Speaking to a crowd of about 300 developers and press, Anuj Gosalia, development manager of DirectX at Microsoft, described DX12 as the joint effort of hardware vendors, game developers and his team. Our work with Microsoft on DirectX 12 began more than four years ago with discussions about reducing resource overhead. For the past year, NVIDIA has been working closely with the DirectX team to deliver a working design and implementation of DX12 at GDC.
According to Microsoft, DirectX 12 will offer a number of major improvements to developers across all Microsoft platforms: Windows, Xbox One and Windows mobile OSes. The new API also seeks to enhance graphics efficiency for modern games by allowing developers to more easily spread tasks across multi-core CPUs, all the while reducing CPU "bottlenecks" that can hinder performance from dedicated video hardware.

The newly announced DirectX 12 will also provide new tools for developers to access "lower-level" functionality of hardware, better known as "coding to the metal." This will eliminate some of the performance hits caused by the API's communication between a game engine and system hardware. Microsoft gave examples using 3DMark benchmarks, where estimates of as much as a 50 percent improvement in CPU performance were found, though of course real-world results will likely vary.

A relief to many, Nvidia revealed that a majority of video cards currently running DirectX 11 are already compatible with DirectX 12, including the company's Fermi, Kepler and Maxwell series of cards. A tech demo was demonstrated at GDC with Forza Motorsport 5 developer Turn 10 Studios showing off a version of the racing title utilising Nvidia's GeForce Titan Black, with the studio claiming that the new API allowed the game to run at a locked 60 frames per second.

Sadly no specific date was given for the DirectX 12 API, but an estimated "holiday 2015" window was offered for games to ship using the API. Developers will have it sooner, with an official SDK later this year and an early access program before that. Microsoft has not yet spoke on which version of Windows will support the new technology.

omg I hope this runs on the GTX 780 Ti's or I'm royally screwed.
Would be silly to make this Win 8 exclusive, seeing how most developers these days still running win7. Without the developer support microsoft will be losing alot of money

You have Kepler, so it'll work.

I seriously doubt this will be for W7 because MS is closed minded like that. However if W9 is like W7 (just more refined) then I'd be happy to upgrade.

So other than blog spam found on Google (as always), do we have an idea of when Windows 9 might get released?

Far out, we just started catching up to DX11

WTF is Kepler ph33x, I have a 650ti will this run Dx12?

Here's hoping it'll run on GCN1.0 as well.

Sounds like a lot of the idea's behind mantle are going into this (reduced CPU overhead etc) so maybe this is a joint effort to reach a middle ground that's not proprietary *shrug*

4xx and 5xx are Fermi
6xx and 7xx are Kepler
8xx and 9xx will be Maxwell (The 750Ti is also a Maxwell)

400's and up will run it, simple

those still hanging onto their 295's time to upgrade

Yeah but the reason for that is because the 360 was only compatible with like DX9 or something so game developers just did cheap s***** ports for PC instead of enhancing them with DX11.

This looks like the Xbone and PS4 will both be DX12 compatible so it's likely Developers will code for it out of the gate.

how does this help gaming on linux take off? oh right, more big companies conspiring amongst each other to keep the little guy out of the picture

Those same companies are also conspiring amongst each other to further the dominance of OpenGL!, a multiplatform API.

I miss the old Qgl...


I like the idea of asking an admin a question, and them knowing the answer - delivered it in a way that we all grew from.

someone on FB just mentioned to me that perhaps the admins of Qgl don't want to do that anymore, and that they deserve to move on and experience the success that they have worked so hard to achieve.


perhaps that opinion has merit.

I believe the PS4 uses OpenGL, I doubt MS will allow Sony to have it on their platform. Sounds like a exclusive thing to Windows and XBOX, MS products!
