Hi all, currently I have built a terrain simulator using Unity 3.5.7 but I seem to be getting lag when trying to optimize for the Iphone 5 and 4 processors etc. Now if I was to upgrade everything to Unity 4.0 does anyone know if I will get some performance improvements as maybe some more bugs have been fixed as Unity 4 came out about same time as Iphone 5.

Therefore any advantages of upgrading to Unity 4? I plan to make game for Android,Windows Mobile etc in the future.

honestly, i havent found too much of a difference, between 3.5.7 and 4.0.1 in terms of performance
