In editor on my quite slow windows tablet I have around 300fps (turned vsync off just to see this) when I export to android with release templates I'm getting significant fps drops. Not all the time but every 5seconds or so. I tried to optimize a lot. I gained 100fps in editor (from 200 to 300)
The game is not so simple 2D game with physics involved (I'm using rigidbody2D - character), custom joystick input and moving background (1024x760). In project settings I use render and physics single-safe thread. The Android I'm testing on doesn't usually have any fps drops but has multiple cores (if that's the problem)
What should I do / try?
