Time scale independent Particle system in unity3d
using UnityEngine;
using System.Collections;
public class ParticaleAnimator : MonoBehaviour {
private void Awake()
{
particle = GetComponent<ParticleSystem>();
}
// Use this for initialization
void Start ()
{
lastTime = Time.realtimeSinceStartup;
}
// Update is called once per frame
void Update ()
{
float deltaTime = Time.realtimeSinceStartup - (float)lastTime;
particle.Simulate(deltaTime, true, false); //last must be false!!
lastTime = Time.realtimeSinceStartup;
}
private double lastTime;
private ParticleSystem particle;
}

If you want to make it a bit more performance wise, You can add this code at the beginning of your Update():

if (Time.timeScale > 0.001f)
{
    return;
}

Helps when you have many ParticleSystem

Now you can use ParticleSystem.playbackspeed instead

Now, in Unity 2017 there is a Delta Time option which we can set to Unscaled.
