[NewBie] My spawn function make my game FPS drop too much !

Unity Engine
1

I want to spawn my NPC base on the spawn point I created, but look like I did something wrong. It works but the FPS drop very low every time it spawns.

public Transform[] m_SpawnPoints;

    public GameObject m_Golem;
    public int SpawnTime;

    void Start () {
        QualitySettings.vSyncCount = 0;
        Invoke ("spawn",1);
    }

    // Update is called once per frame
    void spawn(){
            for (int i = 0; i < m_SpawnPoints.Length; i++) {
                GameObject m_SpawnGolem = (GameObject)Instantiate (m_Golem, m_SpawnPoints [i].position, Quaternion.identity);
            }
        Invoke ("spawn", SpawnTime);
    }

There is nothing wrong with the script that you posted, it should work just fine.
Maybe you forgot to set SpawnTime in inspector.
If you’re planning to Instantiate a lot of objects, then you should consider using object pooling.
Here is a video that will help you set it up: Link

Also I would advice you to modify QualitySettings and other static Unity classes in one function.
Scattering it around your scripts will make your project harder to manage.

The golem that you are instantiating - does it have any scripts that call for debug.logs or anything along those lines? Debug log calls tend to slow things down if they happen a lot.
