i have readed this topic:
http://www.idevgames.com/forums/thread-8...ght=retina
but i'm pretty confused.
my app prepare a framebuffer of size 320x480 and display it at whole screen.
i thought that if i load a 2x image and display it on the screen (scaled down/2) i have the same thing as prepare a framebuffer of 640x960 and not scaling down my sprite.
is it correct?
i hope so...otherwise i'll have to rewrite many of code!
