   Hi guys,
   I just upgraded my application from 0.7.2 to 0.8.1, I know it's a big step but I don't think it'll change much until I realized now my app can only run at <30 fps.

   My app used to run at 60 fps easily and I haven't changed my code much other than just make sure I call the right methods and remove all the obsolete methods.

   Is there anything I should know about this new version? Thanks

   Is this in the simulator or on device? Keep in mind that the framerates you get in the simulator have little bearing on actual device peformance,

   oh i think i got it, this is the part of code that makes the application runs slow

   [dumpText setString:newstring];// to dump some text on the screen

   dumpText is a Label object, so I guess Label is no longer usable to print simple strings on screen

   I'm not sure whether it's changed much since 0.8, but Labels have always been slow; changing the text on a label is as expensive as creating a whole new one - which is pretty expensive. BitmapFontAtlas or LabelAtlas is the way to go for anything that updates frequently.

   yeah,.. i know label isn't recommended but i like the simplicity and in earlier version it doesn't give much trouble so far.

   problem solved! thanks guys!
