It just got my iphone 4 and noticed that some of my games seem more blurry like angry birds. Does anyone else notice this? Its like playing a pc game on an lcd monitor but not in its native resolution.
I wouldn't worry about it. Like the post above me said, they haven't been updated yet. The only game that I can think of that doesn't look better on retina display is Angry Birds.
Hardly any games have updated to support retina display, and only the successful ones will bother since it means redrawing/rendering all of their artwork which obviously costs money. Most future games will likely support it though.
