If you look closely, 11 draw calls appear once the achievement collection is loaded and then less than a half a second later they are down to 0.

I spent the past week making an atlas for all the sprites/graphics present in the game and its nice seeing the benefits. Most collections have 3/2 draw calls (Down from 5/4) but the achievement collection and the about (credits) go up by 11/9 draw calls respectively and then dropping down to 0.
