Hi Kevin,
There are a lot of very inificient things you are doing in your code.
Calling the draw() method directly on each sprite is not recommended, since
it has to set/unset the OpenGL state for each and every one. What you want
to do instead is to create a batch: *batch = pyglet.graphics.Batch*, and
pass this into each sprite on creation. Then, you can draw everything
together with a single call to *batch.draw()* in your on_draw method. There
is a bit of information about Batches in the programming guide, but it does
need more detail:
http://pyglet.readthedocs.io/en/pyglet-1.2-maintenance/programming_guide/graphics.html#batched-rendering
That said, pyglet can easily render thousands of sprites if batched
properly.
