Hi all! Just wondering what counts towards draw calls, tris and verts in empty scene with only Camera and Light? I added a screenshot below, where we can see only 2 objects in Hierarchy, which are not rendered in terms of Mesh Renderer. However Statistics screen shows 2 tris and 4 verts, as if there was one square mesh of two polygons.
You most likely have an image effect script attached to your camera. Image effects require to draw a fullscreen quad. My empty scene (without skybox but solid color) has 0 vertices, 0 triangles and 0 batches.
I think they represent the Screen itself. Think of a plane wrapped on the game view screen and is divided from the diagonal verts as Unity usually has to split all meshes into triangles.
But 4 verts are nothing on modern gpu’s
