Scene load stuck progress on low-end laptop

Unity Engine
1

I’ve been coding a game for my college and recently I decided to test it on a low-end laptop.
It runs without problems when testing it on the computer that I’m coding the game.

On that laptop, when the game starts, it should load a scene with a black screen and a button. However, it takes more than 10 minutes to load the desired scene. I don’t know where to start debugging so I can fix that problem.

The log file generated by Unity and the script to load the scene are below.

The flow is similar to this:

  1. The LoadingScreenManager.LoadScene() saves the scene index and loads the LoadingScene;
  2. Once the LoadingScene is started, it starts a coroutine and runs SceneManager.LoadSceneAsync() with the previously saved scene index;
  3. While the LoadSceneAsync is running, it keeps logging its progress;
    4.LoadSceneAsync never completes.

Script:

using System.Collections;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class LoadingScreenManager : MonoBehaviour
{
    private static int _loadingScreenSceneIndex = 1;
    private static int _sceneIndex = -1;

    public Slider Slider;

    public static void LoadScene(int sceneToLoad)
    {
        _sceneIndex = sceneToLoad;
        SceneManager.LoadScene(_loadingScreenSceneIndex);
    }

    private void Start()
    {
        if (_sceneIndex < 0)
            return;

        StartCoroutine(LoadTargetSceneAsync());
    }

    private IEnumerator LoadTargetSceneAsync()
    {
        var operation = SceneManager.LoadSceneAsync(_sceneIndex);
        while (!operation.isDone)
        {
            float progress = Mathf.Clamp01(operation.progress / 0.9f);

            Debug.LogFormat("LoadingScene - sceneIndex:{0} progress:{1}",
                _sceneIndex, progress);

            Slider.value = progress;

            yield return null;
        }
    }
}

You don’t need another scene just for loading.
Just make a 2nd Canvas that is Activated and showing the Loading bar.
But maybe you have a good reason for the LoadingScene.

Did you make a “Development Build” to see if there are any errors?
