When running certain types of games or even some sophisticated screensavers, you might get an error message from Windows stating that the machine cannot render the said applications. To make sure your PC is fully equipped to run your chosen apps, you can give OpenGL Extension Viewer a try, so as to avoid wasting time downloading and installing programs incompatible with your computer.

Not only does this application display information about your OpenGL 3D accelerator, it also allows you to explore and view details about the extensions, while offering PC experts the choice of disabling them.

This software utility analyzes your PC’s hardware and software, and provide you with details regarding your graphics renderer, such as the DirectX version, the shader model, the OpenGL version and driver version, as well as the renderer model and adapter RAM. Each of these values affect the performance of your PC’s rendering ability, so a better graphics card, along with more RAM modules could significantly boost your PC.

You have the possibility to manually test the performance of your graphics renderer using the tests provided by OpenGL Extension Viewer – if you experience lags or slowing down of the PC, you are advised to choose a lower resolution of your screen.

The tests offered by this application can assess the functionalities from OpenGL 1.1 to OpenGL 3.1, and you can combine screen resolutions, texture LOD bias, multisampling and effects such as PBuffer or fog.

Since it can save you a lot of time you would otherwise spend troubleshooting crashed OpenGL apps, it is useful to know that OpenGL Extension Viewer is a freeware tool, that can be run on a wide range of Windows editions, such as XP and newer.
