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. Not all versions of Windows can run the latest versions of DirectX.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. If you have Windows 10, then you already have the latest version of DirectX installed. To get the latest version of DirectX for your version of Windows, use Windows Update. We recommend that you select Yes to help ensure that your drivers have been signed by a publisher that has verified their authenticity. The first time you use the DirectX Diagnostic Tool, you might be asked whether you want to check if your drivers are digitally signed. In the DirectX Diagnostic Tool, select the System tab, then check the DirectX version number under System Information. To check which version of DirectX is on your PC using the DirectX Diagnostic Tool, select the Start button and type dxdiag in the search box, then press Enter. If your PC doesn't have the right version of DirectX installed (the product box should tell you which one you need), your game might not work properly. DirectX is a suite of multimedia technologies required by many Windows games.
