The last time I checked (September last year) pyglet was around 3x slower than PyOpenGL 2, and 2x faster than PyOpenGL-ctypes (now known as PyOpenGL 3). There's a good chance PyOpenGL has caught up since then, but I haven't checked. > > No support for using pyglet events/windows within a wxPython > > application, however if you use wxPython to create the OpenGL context > > you can trick pyglet into accepting that a context has been created, > > and use pyglet as a replacement for PyOpenGL. > > so basically you access OpenGL calls via pyglet instead of PyOpenGL.

Not that I can think of, unless you're already using pyglet for something else and want to avoid another dependency (assuming PyOpenGL's bindings are up-to-date, again, I haven't checked recently). > > pyglet does not provide the overloaded function names; for example, > > you must specify glVertex3f instead of just glVertex.

It's just a recipe to follow, once you know the trick. There have been some recent threads on this mailing list with some complex examples, or browse through any of the pyglet source code.
