Does anyone know of any GL 3.0/3.1 features that are not available to GL 2.x via extensions?
main thing is that usage is a little different for some features like uniform buffer objects, that and not neededing to type ARB/EXT all the time. As for actual features, I cannot think of any…
The glClearBuffer API is not available as an extension.
Pretty amazing the functionality you get with GL2 + extensions, especially when you consider that most of that functionality is available across a wide swath of platforms. Of course I’m preaching to the choir here.
