DirectX 12 Announced

The DirectX Developer Blog has the official announcement from Microsoft about plans for DirectX 12, saying the next iteration of their gaming API will bring significant performance improvements when it's released in the holidays of 2015:

DirectX 12 introduces the next version of Direct3D, the graphics API at the heart of DirectX. Direct3D is one of the most critical pieces of a game or game engine, and we’ve redesigned it to be faster and more efficient than ever before. Direct3D 12 enables richer scenes, more objects, and full utilization of modern GPU hardware. And it isn’t just for high-end gaming PCs either – Direct3D 12 works across all the Microsoft devices you care about. From phones and tablets, to laptops and desktops, and, of course, Xbox One, Direct3D 12 is the API you’ve been waiting for.

What makes Direct3D 12 better? First and foremost, it provides a lower level of hardware abstraction than ever before, allowing games to significantly improve multithread scaling and CPU utilization. In addition, games will benefit from reduced GPU overhead via features such as descriptor tables and concise pipeline state objects. And that’s not all – Direct3D 12 also introduces a set of new rendering pipeline features that will dramatically improve the efficiency of algorithms such as order-independent transparency, collision detection, and geometry culling.

You seem to be confusing Direct3D with DirectX. OpenGL can't do sound or input.

As for OpenGL, as it's older than D3D, it's interesting that it's not in wider use. Why might that be? I was playing more games in OGL in the 90s than now.

Honestly it's because the committee that steers development of OpenGL put the focus on the wrong things during a crucial time in the early-mid 2000's, and OpenGL fell behind what Direct X 10 was doing. It didn't doom the API, but it made people weary of learning how to use it.

Now it's right there on par with DX10-11, which is why we've seen many more games using it, and Linux support is starting to really take off again. Between SDL, OpenGL, and Pulse Audio, Linux basically has everything Direct X offers.
