What is your opinion on the best practice for determining if an extension is supported on a particular ICD? Currently, I’m using the glGetString(GL_EXTENSIONS) method. But, after using that for a bit, I noticed that it may be easier to just test if the function was returned a null pointer after wglGetProcAddress().
Can anyone speak of the benefit of user either technique? Though the latter appears more straightforward, the former provides more information.
