Sudden drop on game

[GmZaferCelik]

In unity 6000.0.8f1 Game suddenly drops after spawning a model on the scene.

To Reproduce Create a hdrp terrain draw grass use nature renderer to render start the game spawn a model

Expected behavior The second you spawn a model when nature renderer is enabled the framerate drops suddenly.(This is not due to instantiating an object , instantiating an object during runtime in unity causes some drop but this drop is different).
