Today at GDC, Microsoft revealed the newest version of its graphics API, DirectX12. As we’ve been expecting, it’s a “thinner,” lower level API, with less abstraction between software and hardware. That means more involved development, but access to much better performance. Microsoft said that it allows for console-level efficiency on PC, a point they stressed with a ported tech demo of Forza Motorsport 5 running on PC. Forza was running on an Nvidia Titan Black, however, which is a much more powerful GPU than the Xbox One's.
We’ve already spoken about the possibility of Microsoft changing their DirectX API to be more like AMD’s new Mantle API - bringing developers more access to the actual performance hardware. Now it looks they are going to be announcing a whole new iteration of the Microsoft API and not just an update.
A new Twitter account has appeared, called DirectX12, and has teased an announcement set to take place at the Games Developers Conference (GDC) in San Francisco in a couple weeks time.
