Hello! I am working on my first game. A 2D game for iOS where you explore the world by swiping it sideways. The world is made up of a bunch of hills side by side. These hills have different objects on them, like trees, flowers, buildings and such. It used to run at 60 FPS on iPad mini 1st gen. But as we have added a lot of sprites and other game objects the frame rate has dropped considerably. We have around 2500 game objects in the scene right now and would like to add a lot more details to the level. I have a feeling this might be too much. The project has been upgraded from Unity 4.6 Mono to 5 and IL2CPP, and I'm not sure if this might have slowed things down also. From profiling I can see that culling is a big bottle neck. We get all these spikes where Camera.Renderer > Culling > SceneCulling > WaitingForJob takes up to 330ms. Any ideas on things I can try to solve this?
