DirectX 13 Release Date
DirectX 13 is a new version of the DirectX software, an API for video game developers to create games and multimedia applications that provide access to 3D graphics, sound, and input devices. The tool was developed by Microsoft as the latest update for its Windows 11 OS, which had many improvements but lacked support for cutting-edge gaming features. DirectX 13 will be an improvement on its old version, with support for DirectCompute, a hardware-accelerated programming model for 3D graphics applications.

The DirectX 13 API will be a major update to the DirectX 12 API and hardware support for Windows 8.1 devices is said to improve with this next-generation API. According to Microsoft, DirectX 12 will offer developers access to new graphics features and full support for multi-core processors — something that has been lacking in previous versions of DirectX.

DirectX 13 Features:
1. Windows activation:
DirectX 13 is a software component of Windows 10, which will be sold as a separate product.
This provides the user with the feature of Windows 7, 8, and XP. The software platforms are not only aimed at game developers but also will be used by automakers to interface with in-car entertainment systems, home appliance manufacturers that want to enhance their control panels, and many more.
2. Video cards:
Video card makers will have to rewrite their drivers for DirectX 12, or risk having the performance of their products drop substantially. Microsoft said it will make all the changes necessary to ensure that all DirectX 11-based video games are compatible with this new version of the API.
3. Graphic card support:
DirectX 12 will run on all DirectX 11-capable hardware, but Microsoft is pushing for the adoption of its upcoming Windows 10 operating system (which will work across all device types) for the best experience.
4. Multi-threading:
DirectX 12 has a new multi-threading model that efficiently uses each CPU core, allowing the OS to support a maximum number of concurrent threads.
DirectX 12 features easier and faster development for PC games. Thus, it will release in Q4 2015.
What to expect in DirectX 13?
1. DirectX 13 will give an extra push to the multi-threading and that can be used for most of the games.
2. DirectX 13 will have “Programmable shaders”. The DirectX 11 had it but DirectX 13 will really have it as a built-in feature and it can be used to improve rendering, lighting effects, physics simulation, etc.
3. DirectX 13 will support Heterogeneous computing (HTC).
4. Generally new releases of DirectX have a better performance which is all expected from one of the best APIs available. So that is all we can expect from DirectX 13. With DirectX 12, Microsoft has plans to change and improve the video/graphics/3D processing engine in Windows.
The company revealed how DirectX 13 will allow developers to take advantage of this new engine for their video/graphics/3D processing. With DirectX 13, Microsoft has plans to change and improve the video/graphics/3D processing engine in Windows. The company revealed how DirectX 13 will allow developers to take advantage of this new engine for their video/graphics/3D processing.
5. The new DirectX 13 engine will allow more efficiency in the use of the CPU’s processing power which is expected to give better performance to the game.
6. DirectX 13 will allow developers to implement low-level APIs and higher-level APIs in a unified way which can reduce the program code size. This can also help developers to increase the performance of their programs.
7. DirectX 13 will have “Programmable shaders” that can be used for rendering, lighting effects and physics simulation, etc.

Conclusion
DirectX 13 will be a major update to the DirectX 12 API and hardware support for Windows 8.1 devices is
said to improve with this next-generation API. According to Microsoft, DirectX 12 will offer developers access to new graphics features and full support for multi-core processors — something that has been lacking in previous versions of DirectX.
