As stated, what does the “Calls” refer to? Is it the number of draw calls per frame? To that effect, the counts tab only shows 2 next to “draw” even though the count up top is 9.
Personally I don’t recommend to test your scene with this tool.
This timeline is a recorded history of all events, it doesn’t give you realtime data. And could be misleading if your cursor is not on the right spot.
The real informations are contained inside webGPURenderer.info when your run a scene.
.calls: The total number of render calls (render pass + drawcalls + shader compute)
.render.drawCalls: Total draw operations ( GPU calls like meshes )
Calls is always higher than your number of meshes, 9 is normal since it has wider scope.
If you want to “count” assets added / removed in the scene, drawCalls is more accurate. In this screenshot batched mesh count as 1 call. The second one seem related to another mesh , maybe the background? (I didn’t checked the code of this example)
