Microsoft has revealed the latest version of its DirectX API at GDC.
The new version has been designed work across across multiple platforms including PC, Xbox One, tablets and smartphones.
It was claimed he API reduces CPU overhead significantly compared to DirectX 11 and was designed from scratch to take full advantage of advanced GPU hardware features on next-gen systems.
DirectX 12 was shown off on stage with a tech demo of Forza 5 running on a PC powered by an Nvidia Geforce Titan Black by Microsoft DirectX development manager Anuj Gosalia.
Nvidia, which worked with Microsoft on developing the API, will support the latest upgrade on all DirectX 11-class GPUs it has shipped in the Fermi, Kepler and Maxwell architectural families.
“DX12’s focus is on enabling a dramatic increase in visual richness through a significant decrease in API-related CPU overhead,” said Nvidia engineer Henry Moreton.
“Historically, drivers and OS software have managed memory, state, and synchronisation 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 synchronisation. As a result, developers of advanced applications can efficiently control the GPU, taking advantage of their intimate knowledge of the game’s behaviour.”
While initial details have covered the form of the graphics API, Moreton said future Direct3D releases would include new rendering features.
No release date has been set for DirectX 12.
