loading time when showing a sprite the first time

[tom123]

On older devices like iPad2 or iPhone4 there's always a fraction of a second that the game stops, whenever some particular sprites get shown the very first time. If that sprite gets shown the second time, it's all fine.

I don't have Unity Pro, so I couldn't use the exact profiling and now I can't even say a 100% sure that it's because of any toolkit 2d code. But generally, is there any known performance consuming code that gets run every time a sprite is shown the first time?

Unity uploads the texture into VRAM the first time it is drawn. You can avoid this hitch by drawing all your sprites once. It works even if behind a loading screen.
