While Microsoft first announced DirectX 12 several months ago, this is the first time the company has stated publicly it will be a part of the final Windows 10 launch, which is scheduled to happen sometime in mid to late 2015. Microsoft says:
"We especially encourage gamers to help us make this release great for you by becoming Windows Insiders. Game developers who are part of our DirectX 12 Early Access program have even more incentive to join the Windows Insider program. These game developers will receive everything they need to kickstart their DX12 development, including: updated runtime, API headers, drivers, documentation, and samples, all of which will work with the Windows 10 Technical Preview."
Game developers who are a part of the DirectX 12 Early Access program also subscribe to Epic Games's Unreal Engine 4 will now be able to gain access to the DirectX 12 port of that engine, so they will be able to begin development of games using the API long before it is officially released. Microsoft has previously said that the first games with DirectX 12 should start shipping sometime in the holiday season of 2015.
