I am new to pyglet.I am trying to a have a seamlessly scrolling background.
I have tried everything i could find on stack and google. I turned vsync off because it improved the performance in my computer. I have even used batch to draw on my screen. Used the preload function to load my image and in my Game class convert it to sprite.
What else can i do to make my background scroll smoothly?
Thanks in Advance.
This is my code:

glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
glEnable(GL_LINE_SMOOTH)
glHint(GL_LINE_SMOOTH_HINT, GL_DONT_CARE)
pyglet.clock.set_fps_limit(60)
WIDTH = 800
HEIGHT = 600
TITLE = 'Bunny'
def preload_image(img):
pyglet.resource.path = ['../res']
pyglet.resource.reindex()
image = pyglet.resource.image(img)
