I'm writing opengl code in python using the library pyglet. When I draw to the screen using pyglet.graphics.vertex_list or pyglet.graphics.batch objects, they are very slow (~0.1 fps) compared to plain old pyglet.graphics.draw() or just glVertex() calls, which are about 40fps for the same geometry. In Linux the vertex_list is about the same speed as glVertex, which is disappointing, and batch methods are about twice as fast, which is a little better but not as much gain as I was hoping for.

I don't know personally, but I noticed that you haven't posted to the pyglet mailing list about this. More Pyglet users, as well as the primary developer, read that list.

Don't forget to invoke your pyglet scripts with 'python -O myscript.py', the '-O' flag can make a huge performance difference.
