Pyglet simply doesn't handle it correctly on some systems, you have to disable your application window's vsync in order to get it to work. Here's an example script you can run to get a feel for how it works:

import pyglet

# Show FPS
fps = pyglet.clock.ClockDisplay()

# The game window
class Window(pyglet.window.Window):
    def __init__(self):
        super(Window, self).__init__(vsync = False)
        # Run "self.update" 128 frames a second and set FPS limit to 128.
        pyglet.clock.schedule_interval(self.update, 1.0/128.0)
        pyglet.clock.set_fps_limit(128)

    # You need the dt argument there to prevent errors,
    # it does nothing as far as I know.
    def update(self, dt): 
        pass

    def on_draw(self):
        pyglet.clock.tick() # Make sure you tick the clock!
        self.clear()
        fps.draw()

# Create a window and run
win = Window()
pyglet.app.run()
