That is correct, PyOpenGL is just a (technically) simple set of wrappers
around the regular OpenGL calls in the OpenGL library.  The overhead incurred
by this extra (thin) layer is usually negligible for most applications.

I agree, the main bottleneck will be your other code.  Still, one can actually
do quite a lot with Python and PyOpenGL, even if you desire interactive rates.
Check out the (hundreds?) of games developed with PyGame (www.pygame.org), a
library for writing games with Python and PyOpenGL.
