The Game view includes a statistics window that shows you real-time rendering information about your application during Play mode. To open this window, click the Stats button in the top right corner. This displays the window as an overlay in the top right of the Game view. The statistics it contains are useful for optimizing performance. The exact statistics available vary according to the build target.
The Graphics section of the statistics window contains the following information:
|FPS||Frame updates Unity performs per second.|
Main: The total amount of time taken to process one frame. This number includes the time Unity took to process the frame update of your application as well as the time Unity took in the Editor to update the Scene view, other Editor Windows, or process Editor-only tasks.
Render:The amount of time taken to render one frame. This number includes the time Unity took to render the Game View; it does not include the time Unity took in the Editor to render the Scene view or draw Inspector.
|Batches||The total number of batches Unity processes during a frame. This number includes static, dynamic, and instance batches.|
|Saved by batching||The number of batches Unity combined. To ensure good batching, share materials between different GameObjects as often as possible. Changing rendering states breaks batches into groups with the same states.|
|Tris||The number of triangles Unity processes during a frame. This is mostly important when optimizing for low-end hardware.|
|Verts||The number of vertices Unity processes during a frame. This is mostly important when optimizing for low-end hardware.|
|Screen||The resolution of the screen, along with the amount of memory it uses.|
|SetPass||The number of times Unity switches which shader pass it uses to render GameObjects during a frame. A shader may contain several shader passes and each pass renders GameObjects in the scene differently. Each pass requires Unity to bind a new shader which may introduce CPU overhead.|
|Shadow casters||The number of GameObjects that cast shadows in the frame.|
|Visible skinned meshes||The number of Skinned Mesh Renderers Unity rendered in the frame.|
|Animations||The number of animations playing during the frame.|
