When you check the Memory Log it should bring up some form of error surely? Also, I am not entirely convinced that this new 1.4 on IOS is actually Loading Layout by Layout. I notice that when I have a layout with very few sprites, I will still see a poor performance of 7-15fps. This has been a really big disappointment. In all honesty, I can see no noticeable improvement with regards to performance. Does anyone feel the same about this? Or am I just being cynical?
