This is full code, I optimized it even more, but only making 4 OpenGL calls
every frame.

You can't make it any simpler than that, and there is still delay.
Well, I guess I will have to move on to OpenGL ES 2.0, I was actually
planning on rewriting that framework in ES 2.0 entirely, but only after I
finish this game first. So I guess I have to stop working on my game, and
start rewriting my framework now... I HOPE this will do the trick. If not,
then i'm screwed, big time.
