Hi,

well with one sprite I would think you draw 6 vertices, with 100 of sprites you draw 600 vertices. Also, each sprite object takes memory for header and other requirements.

On the other hand the big one may look stretchy and pixellated. So it is more a matter of balancing the look and the resources.

I don't know very much about performance and so on, but the abnormal sprite look nice ( same effect that i realized with 2500 sprite ). But I thought that a single sprite with a lot of resolution will be heavy to load and more separeted sprites will be less heavy to load ( because the camera doesn't render every sprite, but a few number of sprite ), this Thought is right?

Actually one of the main problem you will get is the draw call. IF you have one big texture, it is one call, if you have many little ones and they are all different, then you get a call for each texture.
