crookedvulture writes: Microsoft formally introduced its DirectX 12 API at the Game Developers Conference this morning. This next-gen programming interface will extend across multiple platforms, from PCs to consoles to mobile devices. Like AMD's Mantle API, it promises reduced CPU overhead and lower-level access to graphics hardware. But DirectX 12 won't be limited to one vendor's hardware. Intel, AMD, Nvidia, and Qualcomm have all pledged to support the API, which will apparently work on a lot of existing systems. Intel's Haswell CPUs are compatible with DirectX 12, as are multiple generations of existing AMD and Nvidia GPUs. A DirectX 12 update is also coming to the Xbox One. The first games to support the API won't arrive until the holiday season of 2015, though. A preview release is scheduled for this year.
