Rendering Profiler module

The RenderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
See in Glossary ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating or in your game logic. More info
See in Glossary displays rendering statistics and information about what the CPU and GPU do to render the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary. You can use these statistics to measure the resource intensity of different areas of the Scene, which is useful for optimization.

The chart displays the number of Batches, SetPass Calls, Triangles and Vertices your application rendered. The lower pane displays more rendering statistics, which match the ones shown in the GameView Rendering Statistics window.

The Rendering Profiler module’s chart is divided into four categories as follows:

Module details pane

When you click on the Rendering Profiler module, the details pane in the lower half of the window displays detailed rendering statistics. These statistics are similar to the statistics shown in the Rendering Statistics window.

In the top left of the details pane, select Open Frame Debugger to open the Frame Debugger, which gives you information on individual drawcalls that rendered the frame.

These statistics are also available via the ProfilerRecorder API and in the Profiler Module Editor so you can add them to a custom Profiler module.

Availability in Players

The Rendering module Profiler counters are also available in Players. Use the ProfilerRecorder API to access Render Profiler module information in Players. High level counters are also available in Release Player.

The following example contains a simple script that collects “SetPass Calls Count”, “Draw Calls Count” and “Vertices Count” metrics and displays those as TextArea.

using System.Text;
using Unity.Profiling;
using UnityEngine;
 
public class RenderStatsScript : MonoBehaviour
{
    string statsText;
    ProfilerRecorder setPassCallsRecorder;
    ProfilerRecorder drawCallsRecorder;
    ProfilerRecorder verticesRecorder;

    void OnEnable()
    {
        setPassCallsRecorder = ProfilerRecorder.StartNew(ProfilerCategory.Render, "SetPass Calls Count");
        drawCallsRecorder = ProfilerRecorder.StartNew(ProfilerCategory.Render, "Draw Calls Count");
        verticesRecorder = ProfilerRecorder.StartNew(ProfilerCategory.Render, "Vertices Count");
    }
 
    void OnDisable()
    {
        setPassCallsRecorder.Dispose();
        drawCallsRecorder.Dispose();
        verticesRecorder.Dispose();
    }

    void Update()
    {
        var sb = new StringBuilder(500);
        if (setPassCallsRecorder.Valid)
            sb.AppendLine($"SetPass Calls: {setPassCallsRecorder.LastValue}");
        if (drawCallsRecorder.Valid)
            sb.AppendLine($"Draw Calls: {drawCallsRecorder.LastValue}");
        if (verticesRecorder.Valid)
            sb.AppendLine($"Vertices: {verticesRecorder.LastValue}");
        statsText = sb.ToString();
    }
 
    void OnGUI()
    {
        GUI.TextArea(new Rect(10, 30, 250, 50), statsText);
    }
}

The Rendering Profiler module information belongs to the ProfilerCategory.Render Profiler category.

If you want to highlight the selected Rendering counters in a custom module, use the Module Editor to configure the chart and detailed view.
