no by batch i meant
batch = pyglet.graphics.Batch()
for img in images: #list of AbstractImages
pyglet.sprite.Sprite(img, batch=batch)
batch.draw()
which should be much faster than:
for sprite in sprites:
sprite.draw()
why is it faster to check each tile's position to be on the screen
than just addressing them by tile[x][y] with two nested loops??
