I'm trying to port existing wp7 app to wp8 and there is problem with maps. Map is made from 6 tiles. Everything is working well, but pinching is terrible. Works much worse than on WP7.
Anything changed in WP8? What I have found is small information from microsoft presentation which says that in WP8 some things from pinch and strech were improved
