DirectX 12: A Complete Installation and Compatibility Guide for Contemporary Computing.
DirectX 12 from Microsoft is a landmark technology that aims to revolutionize both the gaming world and graphics-heavy professional applications in terms of performance and power usage. It is a part of modern Windows ecosystems and hence works flawlessly. However, using it on different operating systems is not that easy. This manual is about the different steps of getting, upgrading, and using DirectX 12 on various platforms.
Basic Installation on Windows 10 & 11.
DirectX 12 comes with the operating system by default for Windows 10 and 11 users. However, the best way to make sure it is up-to-date is through a built-in Windows Update procedure. To get there, open the Start menu, click on the Settings icon, and proceed to Update & Security > Windows Update. Here click on Check for updates, install any that are listed, and especially look for optional updates. This approach has the least odds of running into problems. At times, it may be necessary to carry out manual installation from the official Microsoft Download Center. This procedure is normally intended for situations involving old setups.
Old Windows Restrictions.
The distinction between which versions can or cannot run DirectX 12 should be kept in mind at all times: only Windows 10 and later versions are DirectX 12 compatible. Unlike these, Windows 7, 8, and 8.1 have been built in such a way that it is impossible for them to support DirectX 12. In these cases, the latest versions one can reach are DirectX 11.1 and 11.2, correspondingly. People who use these platforms but still want to have access to the advanced graphics features have no other choice than to get a new one.
Cross-Platform Ploys: macOS and Linux.
Talking about non-Windows systems, it is a quite different story since DirectX 12 is not designed for them.
On macOS: Compatibility layers are the only solution. It is a commercial and supported version of the Wine project called CrossOver by CodeWeavers that has started providing support for some DirectX 12 games. Nevertheless, the quality of performance and the degree of compatibility depend wholly on the respective applications and it is also possible that there will be some compromises. It can be regarded as a feasible, though far from certain, way of executing a small number of Windows programs.
On Linux: The route is very complex. The open-source Wine project which is the base for CrossOver is constantly improving its DirectX 12 support, but it is still in an experimental stage and only a few titles are supported. As for CrossOver, it also offers a more user-friendly interface and better support on Linux. However, the most complete and highest quality method is to have a genuine copy of Windows installed in a virtual machine with GPU passthrough (e.g., VMware, VirtualBox) although it requires a lot of system resources.
One of the most attractive options for Linux users is to switch completely to native APIs that have been designed for high-performance such as Vulkan and OpenGL. Presently, almost all games and professional software tools support these universal standards for cross-platform, thus they can obtain the best possible performance without the need of a compatibility layer.
Conclusion and Recommendations.
DirectX 12 is still a very important part of the Windows graphics stack and the users of compatible versions can easily keep it in good shape. On the other hand, owners of macOS and Linux machines who want to use DirectX 12 have to resort to third-party solutions that come with some drawbacks, such as decreased performance, less compatibility, and longer and more complex setup. In the future, when the industry advances further, Vulkan will become a strong and platform-independent alternative for graphics-intensive tasks. To decide whether putting money in a Windows set-up or making use of native Linux APIs is the most advantageous move one has to clarify what are his/her main activities, e.g. gaming, designing, or simulating.
