Free collection of application programming interfaces (APIs)


DirectX is a free collection of application programming interfaces (APIs) for programming sound and graphics. This enables developers, especially game developers, to create fully-featured video games that run perfectly on Windows. The majority of users are not even aware of how DirectX operates, and they don’t really have to. It runs exactly when it is supposed to, without informing the user. Interacting with DirectX, however, can be somewhat complex and it will require programming skills.

Although you can install DirectX on any working computer, a good chunk of users will never require it. The tool runs as you’re playing your favorite game built with DirectX, and that’s about it. You will have to understand it better only if you’re looking to program with the tool yourself. DirectX has one of, if not, the most flexible runtime process among this category.

So, basically, DirectX is a series of Windows interfaces. Skilled developers program into the DirectX API, allowing their programs and games to interact properly with graphics and sound cards. In turn, creators of graphics and sound cards recognize DirectX. Thus, they know what needs to be done when an app designed with DirectX is accessing their functions.

Games utilizing DirectX can make use of multimedia accelerator features embedded in your PC hardware more effectively, enhancing your overall experience in terms of multimedia.

Just download and install the program and you’re all set. Updates are usually available through monthly Windows Updates. There aren’t any stand-alone packages for such DirectX versions.

DirectX is only available on PCs and is developed by Microsoft exclusively. It is a free download required by games with high graphics. All in all, DirectX makes it super convenient for developers to release the full power of graphics cards (as well as virtual video cards) for the ultimate gaming quality. It further improves picture and rendering time, as well.

DirectX 12 is licensed as Freeware for Windows (32-and 64-bit) operating system from components without any restrictions. It is available to everyone and can be downloaded for free!
