When we are using graphics and animation software, it may require OpenGL for rendering the graphics. Whether it is a video game or video player, it does require one or other type of video renderer. Usually, we get a choice from a number of renderers like DirectX, OpenGL or software based rendering. But so many times an application depends solely on OpenGL.
In order to see which version of the OpenGL is supported by our PC, we can use a freeware OpenGL Extensions Viewer. It can analyze our hardware and give full details about the version of OpenGL available on a system. Not only it shows the OpenGL version supported by PC hardware, it can also display which extensions are available such as OpenGL 3D accelerator and Vulkan 3D API.
After launching OpenGL Extensions Viewer, it may take a few minutes before it is going to display a summary of OpenGL support for your system. In the summary, it displays renderer, adapter RAM, monitors, screen resolution, operating system version, processor being used, OpenGL version supported by hardware, OpenGL driver version, DirectX version supported, DirectX Shader version, Vulkan version available and more.
For more details about the particulars of any of these, we can pick the respective section from the OpenGL Extensions Viewer interface. We can choose to view the display modes and pixel formats, rendering tests, OpenGL hardware database, OpenGL report, Vulkan report, CPU report etc.
Under the CPU report, it basically shows the details of the processor rather than the capabilities of the CPU. For example, it will show the CPU name, family, code name, technology used, model number, but won’t display all the instruction sets supported by it.
We can save the whole report generated by this software in form of an XML file. The same software is available for macOS, Android and iOS.
