Ok after a discussion on IRC about it with noel, this transpired:

SuperStrict
Framework Pub.OpenGL
Import Brl.StandardIO
Import Brl.GLGraphics
Try
GLGraphics( 320, 240, 0 )
Print String.FromCString(glGetString( GL_RENDERER ))
Print String.FromCString(glGetString( GL_VENDOR ))
Print String.FromCString(glGetString( GL_VERSION ))
Print String.FromCString(glGetString( GL_EXTENSIONS ))
Catch o:Object
Print o.ToString( )
End Try
End

Problem is, we have to open an opengl window, but if that fails there is always try and catch.

What I need to know next is: what strings to look out for? What will happen on 95, 98, Me and windows NT machines?
