title: Unity 2D side scrolling game stutter/jerk/lag issue when run on iOS devices
body: <p>I just want to say thanks in advance for anyone you can provide some help on this we're completely stuck at the moment.</p>
  
  <p>Project Scenario : -> 2D side scrolling game with simple 2d sprites -> Camera is orthographic and stays in its place (camera doesn't move) -> My Character (A camel) is also static and does not move. -> The sprites (Platforms) move from right to left (movement done by script) -> Project Video is uploaded here (running on iphone5). It clearly shows the small hiccups and jerks.</p>
  
  <p>Issue : The game works very smoothly on Android devices and Unity Editor (no spikes on the Unity profiler as well) But, when i run it on iOS devices (iphone5, iphon5s) the motion of my sprites is jerky. Like it will move smoothly for like 1 second and then a small hiccup/jerk of a split second occurs. This results in lag and lagging motion of the game which is very annoying as i am unable to get the right quality for iOS.</p>
  
  <p>Things i have tried : -> I have studied many possible solutions on various threads and forums but none issue seems to be working for me :-( -> I have tried different scripting techniques like use Lerp function for movement, tried putting the code in LateUpdate and also FixedUpdate. -> I also turned off vSync in project Quality settings but no luck :-( -> I also tried the movement without the script by making an animation of the sprites to move from right to left. -> I tried making the project from the latest Unity 5.1 as well but still the same lag :-( -> I tried reducing the sprite sizes to very low (low quality pixels) but still issue prevailed. -> I also tried to change the camera to perspective view to see if it reduces the jerk or not</p>
  
  <p>I am sure lots of other people around must have faced this issue while making a 2D game of such sort. I hope someone must have overcome the issue and can please help me with this. This has been an issue with me for long now ...</p>
  
  <p>I would really appreciate any help ... any new technique in unity or any better optimised logic of making such a 2D game in Unity. Thanks.</p>
  
  <p>Looking forward to everyones input.</p>
