Will my ipad 3 make use of the HD in HD labelled games? Do they simply look a bit better than non hd versions? Thanks!
The label is fairly meaningless as a lot of the older "HD" games don't have retina graphics. Generally though, most recent iPad or Universal (compatible with iPhone and iPad) games are retina on the iPad 3. There are some though that need a more recent iPad to get the retina graphics.
The term HD is often misused so sometimes meaningless. But generally yes, hd is more for ipads. More important thing is whether they are ipad retina. Just ask in a gamethread if you are not sure.
