Hi all, There is a lot of vegetation in the scene (I used this: https://assetstore.unity.com/packages/templates/tutorials/3d-game-kit-115747), so I marked them static. To check whether static batching is working, I disabled them at the beginning, click "Play" button, check the profiler, then turn them on, check the profiler again (I turn on/off the static objects few times, not only once). The FPS is decreased from 150 to 75. Below is the result. Before: After: In my opinion, the "draw calls" should be the same or not much different no matter I turn on/off static objects. Did I understand correctly? UPDATE: I tried to uncheck Static and see what difference now, and below is the result. Uncheck Static: As you see, Instancing is used instead of static batch. And this is ridiculous, draw calls are much lower than static batch. Is is expected behaviour because I turn on GPU Instancing for few major materials only without custom code ?
