Retina backdrop picture

Are there any difference in apperance if a backdrop picture comes from 1024x768 or 2048x1536 source ?
I have a very detailed backdrop in the low quality but needs to decide if I should scale everything by 2.
Using Skinman by the way which is a super Windows application for this kind of work :slight_smile:
