OpenGL Extension Viewer, developed by Realtech VR, is a utility tool that allows you to check the performance of your OpenGL extensions. OpenGL is a widely used application program interface for graphic images, and some programs require it to run properly. With this tool, you can easily view all of your OpenGL extensions in a tree display and disable any that you don't need. Additionally, you can use the program to assess the rendering capabilities of your computer. While running the tests may slow down your PC temporarily, it is a valuable tool to ensure your computer is up to par with OpenGL requirements sooner rather than later.
Pros: The installation process is straightforward, and the program is easy to use.
Cons: Running the tests may slow down your PC, and the testing process itself can take some time.
Overall, OpenGL Extension Viewer is a useful utility tool for anyone who wants to check the performance of their OpenGL extensions and ensure their computer meets the necessary requirements.
