To understand how this bottleneck is reduced, it's necessary to describe how a computer displays graphics in the first place. Working with Nvidia® and AMD, Microsoft has developed DirectX 12 to benefit not only high-end performing machines that use high-memory dedicated graphics cards, but also mid- to low-tier computers that may feature integrated graphics. One of the hallmark features of DirectX 12 will be its ability to simultaneously allow CPUs to send multiple commands to the GPU, significantly reducing the bottleneck that DirectX 11 suffers from. In anticipation for the Windows 10 rollout, and, in turn, the arrival of DirectX 12, here's a snapshot of what to expect from the next-generation API. While we have yet to see games that are built ground up on DirectX 12, it is expected that these games will hit the market as soon as the end of 2015. With the rollout of Windows 10, DirectX 12 will replace the seven-year old DirectX 11, which currently commands 70% of the PC gaming market.

DirectX 12 will unlock next-generation graphics for games that utilize new game engines like Unity, CryENGINE, and Unreal Engine 4.

One of the most exciting things to come along with Windows 10 rolling out later this year will be the release of DirectX 12 during the 2015 holiday season.
