An OpenGL® display driver is a computer file that enables hardware and software to recognize OpenGL® code for rendering computer graphics, especially in PC games. An OpenGL® video driver is a type of video card driver that expands the performance of the operating system and video card, specifically for use with OpenGL®. It is often developed for a specific operating system and video card.
An OpenGL® display driver is a type of computer file that allows a machine’s hardware and software to correctly identify and recognize OpenGL® code and programming. Many different types of programs can use OpenGL® to render computer graphics on a Personal Computer (PC), especially in PC games that use three-dimensional (3D) graphics. For these programs to work properly and display graphics accurately, the operating system (OS) must be able to recognize how these graphics are produced. An OpenGL® video driver is a file used by the operating system and a graphics card to do this.
The purpose of an OpenGL® video driver is similar to how other drivers are used by a computer. When a computer starts up, also called “bootstrapping” or “booting,” there is software called BIOS (Basic Input/Output System) on the motherboard. This software manages the startup of hardware such as processors, random access memory (RAM), and hard drives. At some point, however, these functions are “handed over” to the operating system or operating system on a computer, at which point the operating system takes over and handles further functions.
In order for the operating system on a computer to recognize and interface correctly with various hardware components, however, it uses files called “drivers.” These files are often developed for a particular operating system and certain hardware components, which can be quite general or very specific. Video card drivers, for example, are typically used by the operating system on a computer to recognize a video card and to work properly with it.
An OpenGL® video driver is a special type of video card driver that expands the performance of the operating system itself and the video card. Rather than allowing the operating system to simply recognize and use the card, this type of driver is developed specifically for the use of OpenGL®. It is a graphics library commonly used to allow games and other graphics applications to display video in a way that can be recognized by a wide range of systems.
However, for the OpenGL® platform to be fully effective on a computer, an OpenGL® video driver may need to be installed on it. This type of driver is often based on a specific operating system, not just a particular platform such as Windows®, but also the version of the operating system being used. An OpenGL® video driver is also usually developed for a specific video card, although some developers may create drivers that work with a variety of cards they design. The best driver for a given card is usually provided by the company that makes it, although some third-party drivers can also be effective.
