Quick suggestion - only do the translate/rotate when you are actually
changing the rotation, i.e.
def on_draw ():
window.clear()
vertex_list.draw(gl.GL_LINES)
def update (dt):
rotation[1] += 90*dt
gl.glLoadIdentity()
gl.glTranslatef(0, -128, -512)
gl.glRotatef(rotation[1],0,1,0)
That runs at 60fps and smoothly on my machine (3GHz P4 / radeon x300).
