Strange spikes in fps due to rendering

Hey guys,

when i run my profiler on a Android device, i see very strange spikes in fps because of the rendering. I really dont understand where they come from, since i dont even move in the game. So basically whats on the screen stays the same but the fps drop frequently.

What i did to boost my performance:

  • i set the quality on low
  • disabled VSync (but since i locked the frames at 60 and im running on a Android device its still on)
  • disabled shadows
  • i dont use light
  • Only have one camera
  • compromised the size of all my sprites

But those spikes just dont disappear, no mater what i try. I even try to switch to URP, but that made it even much worse.

Maybe someone can help?

I dont really understand why, but after i removed “static batching” from some objects the spikes stopped
