    So I have a top down camera and I have also set my particles culling to "pause and catch up". I have also set-up a button to show and hide the particles game object as a test. On my low end mobile I get a bad FPS around 20fps with the camera no where near the particles. Then when I use my button to turn them off my FPS goes right up. I thought my particles weren't rendering out of the camera view but they obviously are and they are obviously taking up resources. Did i misinterpret the culling mode?

    So to simplify my FPS changes when I show and hide particles even though they are no where near the camera.

    Thanks

    Enable the "Show Bounds" checkbox in the Scene View Overlay, and see if your bounds are what you expect. It is this box that is used to determine if a system will be simulated or not.

    I don't think it's the bounds. My particles are really no where near the camera a lot of the time. Here is an example.
