Getting the Rendering time of a Unity Game scene on Android

Question

在Android平台上运行时，如何获取（并记录）统一游戏中场景的确切渲染时间 （ 仅统一渲染部分所需的时间 ）（ 不使用探查器作为探查器会增加一些额外的开销）

Answer 1

I don't know of any available API call. Time.unscaledDeltaTime is the real-time between calls to Update() (so includes gpu and cpu processing). The best I can offer is, based off of the lifecycle linked in OP's comments, start a timer immediately before the Render part and stop it immediately after using:

private void LateUpdate()
{
    StartCoroutine(RenderTimer());
}

IEnumerator RenderTimer()
{
    var started = YourHiResTimerHere.Now;

    yield return new WaitForEndOfFrame();

    var ended = YourHiResTimerHere.Now;
    var gpuWait = ended - started;
}

Keep in mind that most C# timers have terrible resolution (about 20ms at best)
