title: Simple 2D Unity Game has periodical jerkiness
body: <p>I've made a simple 2D game in Unity using the application Tiled for the tilemap, but when I run it, every now and then the screen will jump like it has a quick fps drop. </p>
  
  <p>I'm not sure what would be hurting the performance of the game, because it is not performing any demanding tasks. My only guess is that it could be the large tilemap I'm using, but I feel this is not the problem because the game was still jerky when the map was not large. Furthermore, I tried scaling the map to an even larger size but it didn't make the performance any worse than it already was.</p>
  
  <p>Does anyone know what could be causing the performance issue here? Thanks.</p>
