OpenGL Extension Viewer is reliable software which displays the vendor name, the version implemented, the renderer name, and the extensions of the current OpenGL 3D accelerator. Many OpenGL extensions, as well as extensions to related APIs like GLU, GLX, and WGL, have been defined by vendors and groups of vendors. The extension registry is maintained by SGI and contains specifications for all known extensions, written as modifications to the appropriate specification documents. The registry also defines naming conventions, guidelines for creating new extensions and writing suitable extension specifications, and other related documentation.

OpenGL Extensions Viewer is free of charge and was awarded by Softpedia as 100% FREE No Spyware, No Adware, No Viruses

Report
The OpenGL diagnostic tool performs some OpenGL initialisation and graphical test. It will use the desktop resolution. So in case of slow downs or initialisation errors, use a smaller desktop resolution. 

OpenGL 1.1 : use the standard OpenGL without extension usage.
OpenGL 1.2 : OpenGL test using GL_lock_array and glDrawElement.
OpenGL 1.3 : OpenGL using GL_lock_array and multitexturing.
OpenGL 1.4 : OpenGL test using GL_lock_array and multitexturing using a DOT3 shading and an ARB vertex program code.
OpenGL 1.5 : OpenGL test using Vertex Buffer Object.
OpenGL 2.0 : OpenGL test using a GLSL 1.0 program.
OpenGL 2.1 : OpenGL test using pixel buffer object.
OpenGL 3.0 : OpenGL test using OpenGL 3.0 Forward Context (only supported under Windows).
