OpenGL extension viewer is a well-grounded benchmark utility that displays all of the hardware’s information about the current version, your graphics renderers such as DirectX version, Open GL version, Vulkan API, shader model, and driver version along with fetching information about your OpenGL 3D accelerator, and showcasing every little detail about the extensions so users can make the calculative decision on which hardware to upgrade to get the most out your performance in intensive computing applications and high graphics PC games. This utility also supports extensions related to APIs such as GLX, GLU, and WGL. The extensions are managed by SGI and contain specifications for popular extensions. 

Features of OpenGL extension viewer

Provides accurate benchmarking results
If you want to gauge your computer performance to see if it matches your requirement for running applications at optimal settings, OpenGL extension viewer lets you perform intensive benchmarking and display accurate parameters on how the hardware is faring and lets the user make an informative decision on whether they should upgrade their hardware or not. Users can also conduct various tests using this utility by selecting the rendering tests section. That way users can easily test their monitor or any other hardware like processors installed on your computer.

Modern intuitive interface for faster benchmarking
Despite its diversity in benchmarking hardware, the interface of the OpenGL extension viewer is designed in a presentable and well-organized manner and is divided into two separate sections for easy navigation and displaying real-time benchmarks. The left side of the screen consists of screen presets in the menu with its main functions while the right side contains the display screen on which the menu’s function will be displayed once the user selects an option, so you can keep track of your benchmarks without getting sidetracked.

It features a vast database of extensions
OpenGL extensions have a vast database of all the popular extensions for every piece of hardware that users can visualize all of the renderers, extensions, and vendors available on the system for each hardware installed on the PC and fetches detailed information about them when selected.

Several other functionalities
Aside from regular benchmarking, OpenGL extension viewer has several tricks up in his sleeve that can expand many functionalities and execution of mainstream features like defining naming conventions, guidelines for creating new extensions, and so on.
