Not sure if that demo actually *requires* GLSL version 3.3, or whether 
it just declares that because it's what my machine has. Your driver 
apparently would give you 3.3 if it were a core context (I haven't seen 
that before), but only 1.3 for compat context. OpenGLContext is rather 
old, so it doesn't have support for core profile contexts.  That said, 
you could likely take a core-profile demo, copy the shaders over to it, 
and run the result.

Good luck,
Mike
