NVIDIA: DirectX 12 Is Huge Improvement for Gaming

NVIDIA: DirectX 12 Is Huge Improvement for Gaming

Microsoft today introduced DirectX 12 at the annual Game Developers Conference (GDC) in San Francisco. DX12 is Microsoft's latest version of the graphics API that is the dominant standard in the growing, $25 billion PC gaming industry. Developers have been asking for a thinner, more efficient API that allows them to control hardware resources more directly. Despite significant efficiency improvements delivered by continuous advancement of existing API implementations, next-generation applications want to extract all possible performance from multi-core systems. Developers also want to take direct advantage of advanced GPU hardware features, from which developers are currently insulated to provide fool-proof usage. DirectX 12 was designed from scratch to provide the infrastructure for these advanced applications.

DirectX 12 will mirror many of the improvements AMD implemented in its own Mantle API. The big news today was that DX12 will support more than just the PC and will work on existing hardware. Microsoft will bring DX12 to all of its platforms, including the Xbox One and even Windows Phone. Which hardware will be DX12-compatible? AMD said all of its Graphics Core Next-based Radeon GPUs (i.e. Radeon HD 7000 series and newer) will work with the new API. Nvidia pledged support for all Fermi, Kepler, and Maxwell (i.e. GeForce GTX 400 series and newer) parts.

The DirectX 12 API would not be limited to desktop PCs but since AMD has hardware implemented in Microsoft’s Xbox One, the benefits of the latest Direct3D 12 API would be forwarded to the next generation console. Turn10 studios demoed a short video of FORZA 5 running with new API maintaining a smooth 60 FPS frame rate with all new rendering features implemented. Since Xbox One has full support of DirectX 12 API, we will see upcoming games for the console to offer improved performance.

Next up was Eric Mentzer from chipzilla, Intel, who announced that their Fourth generation of Haswell CPUs will feature full support for the DirectX 12 API. However, there’s a restriction and only processors which feature the Iris and Iris Pro graphics chip will adopt the new Direct3D API. Intel recently announced that their Haswell refresh platform processors with unlocked K-Series design will feature the Iris Pro graphics chip. This means that Intel’s upcoming generation of processors will fully be compatible with DirectX 12 and offer improved speed and driver support in multiple apps and games. The Iris Pro with DirectX 12 can now become a great addition for NUCs and Mini PCs such as Gigabyte BRIX resulting in a great platform for Steam Machines.
Lastly, we have NVIDIA on the desktop front who announced that DirectX 12 API would be supported by not just their Maxwell and Kepler GPUs but also by their Fermi core architecture. Fermi was launched back in 2010 and NVIDIA supporting the GPU architecture to this date is great news for those users who still have Fermi GPUs running in their rigs. Following is NVIDIA’s note on the DirectX 12 API:

Speaking to a crowd of about 500 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. Read more:

Gosalia demonstrated the new API with a tech demo of the Xbox One racing game Forza running on a PC powered by an NVIDIA GeForce Titan Black. In addition, our software team has provided a driver to game studios to facilitate further design feedback as well as actual game development. 

A critical factor in the adoption of any new API is the size of the available market. In the past, feature adoption has been muted by lack of support in the substantial console market, as well as absence of feature deployment on popular versions of the Windows OS. With DX12, there is an unprecedented convergence of APIs and breadth of support. DX12 will span PCs, XBox One, tablets and even phones.
In addition, NVIDIA will match Microsoft OS support for DX12. Over 70% of gaming PCs are now DX11 based. NVIDIA will support the DX12 API on all the DX11-class GPUs it has shipped; these belong to the Fermi, Kepler and Maxwell architectural families. With more than 50% market share (65% for discrete graphics) among DX11-based gaming systems, NVIDIA alone will provide game developers the majority of the potential installed base.
The genesis of DX12 can be found in technology trends. GPUs have continued to rapidly increase in performance, while single-core CPU performance has been gated by power limits. Multi-core CPUs have provided some advancement but still trail GPUs in peak performance. In parallel, applications have embraced task-parallelism, adopting sophisticated scheduling systems to scale performance with the number of CPU cores. This has in turn driven the need for an API that scales similarly with core count. GPU performance can be exploited three ways: drawing better pixels, more pixels and more objects. We have reaped much of what can be gained from pixels. DX12’s focus is on enabling a dramatic increase in visual richness through a significant decrease in API-related CPU overhead. Historically, drivers and OS software have managed memory, state, and synchronization on behalf of developers. However, inefficiencies result from the imperfect understanding of an application’s needs. DX12 gives the application the ability to directly manage resources and state, and perform necessary synchronization. As a result, developers of advanced applications can efficiently control the GPU, taking advantage of their intimate knowledge of the game’s behavior. NVIDIA

We will have an article on Qualcomm’s support for DirectX 12 API shortly but its great to see that all the major vendors are onboard the DirectX 12 bandwagon. Stay tuned for more information and videos of the event in a short time.

You All have to notice That AMD + Nvidia and MS working on New DX a long time ago.

Fixed for u,no need to thank me. :D

AMD only have to worry about their hardware working, not everyone else's

U are right,thats why DX12 is "Designed in close collaboration between Microsoft and Nvidia" .
I really don`t get it why so many ppl that use AMD HW are so butthurt over this!

It´s amazing what some competition can do, even from a company that´s much smaller than Microsoft!

Thanks AMD! From a Nvidia user!

And this is why nobody wants AMD out of the game, imagine a PC world with single core,32bit,single channel. They always force the big companies to make advancements in technology because of their innovations.

Competition always leads to huge jumps in architectures.
