Through the period of 1995-1997, the DirectX library went through several version changes to reach version 5.

DirectX 2.0 was released in June 1996 and just four months later, the DirectX 3.0 APIs were released. It was initially released under the name Windows Game SDK. The first version of DirectX was not released at the same time as Windows 95 but shortly after it in September 1995. The various components of the DirectX API provide low-level access to the hardware running on Windows based operating systems. DirectX APIĭirectX is a collection of Application Programming Interfaces (APIs) developed by Microsoft. This lesson is not designed to teach you C++ programming It is assumed that you already have developed this skill. In this lesson, you may encounter some C++11 (threading, lambdas, smart pointers) or C++17 features that will not be explained in detail.

You should already have some experience programming with C++. This lesson is written with no assumptions about your current skill level and assumes you have never written a graphics application before. Most gaming studios will only hire you as a graphics programmer if you have some experience with at least one of the new graphics programming API’s (DirectX 12 or Vulkan).ĭon’t worry if you are a total noob when it comes to graphics programming.
#Directx 12 install update
The previous versions of the DirectX SDK will still work but if you are either looking for a job in the game industry or just trying to update your knowledge and skills in the area of graphics programming, it is required that you learn the DirectX 12 SDK. As with all things, the first time you encounter something it may seem daunting or too difficult to learn but if you are persistent in your desire to learn this new SDK, the rewards will be well worth it. It is true that this increased complexity makes learning DirectX 12 harder than learning previous versions of the DirectX SDK.
#Directx 12 install driver
Providing the developers with the tools to implement their own resource management takes that responsibility away from the driver implementation and often allows for performance improvements if done correctly.īut with great power, comes great responsibility. Tracking of resources by the driver is often unnecessary if it can be assumed that the application programmer can perform this task with much less overhead.
#Directx 12 install drivers
Drivers needed to track the lifetime of every resource that was used by the rendering pipeline. One example of the driver overhead that is present in previous versions of the DirectX SDK is resource management. Much of this overhead could be avoided if you give control back to the developers. Vendor-specific driver implementations were often complex and imposed a CPU performance overhead that the developer had no control over. The primary reason for this change is the demand from the gaming industry to provide a rendering SDK that gives more power and control to the graphics programmer. DirectX 12 is the successor of the DirectX 11 SDK and represents the largest architectural change to the SDK since the inception of DirectX.
