Rendering Statistics Window
The has a button in the top right corner. When the button is pressed, an overlay window is displayed which shows realtime rendering statistics, which are useful for optimizing performance. The exact statistics displayed vary according to the build target.
The Statistics window contains the following information:-
| Time per frame and FPS | The amount of time taken to process and render one game frame (and its reciprocal, frames per second). Note that this number only includes the time taken to do the frame update and render the game view; it does not include the time taken in the editor to draw the scene view, inspector and other editor-only processing. |
| Draw Calls | The total number of meshes drawn after batching was applied. Note that where objects are rendered multiple times (for example, objects illuminated by pixel lights), each rendering results in a separate draw call. |
| Batched (Draw Calls) | The number of initially separate draw calls that were added to batches. “Batching” is where the engine attempts to combine the rendering of multiple objects into one draw call in order to reduce CPU overhead. To ensure good batching, you should share materials between different objects as often as possible. |
| Tris and Verts | The number of triangles and vertices drawn. This is mostly important when optimizing for low-end hardware |
| Screen | The size of the screen, along with its anti-aliasing level and memory usage. |
| SetPass | The number of rendering passes. Each pass requires Unity runtime to bind a new shader which may introduce CPU overhead. |
| Visible Skinned Meshes | The number of skinned meshes rendered. |
| Animations | The number of animations playing. |
