Hey, Do you encounter scrolling lag on this page using Safari when you're zoomed in? (two finger pinching) http://kurrytran.blogspot.co.il/2011/07/simple-ios-5-tutorial-using-storyboard.html I'm running ML on freshly installed partition and this thing lag when zoomed it, to the point it isn't usable for me. P.S - I've tested this using discrete card via gfxCardStatus and it didn't help. Also should note that when I'm on actual size mode I have no scrolling lag. EDIT: Read the thread http://forums.macrumors.com/showthread.php?t=1412196 and then installed Chrome Beta, which has no problem rendering this page zoomed in. That's pretty good solution until Safari will fix its zoom-rendering issues.
