I tried many options and this problem is very annoying, I created simple folio with JPEG (Max quality) articles, when I swile to the left/right I definitelly see 1-2 sec delay,
my clients are unhappy, what can I say to them... let's wait until Adobe fix this.
I also tried PDF articles but it's not ideal too.. it's some kind of 'focusing' for same 1-2 seconds.
1024x768 is not an opion, it looks awful on retina screen (but works fine).
Adobe, please fix it in next release, iPad3 becoming popular and de-facto standard. It's not a feature request.
