FPS drops with Particle System

#1

I am starting to use zame-haxe-particles from @restorer and I found problems with FPS with this small piece of code:

class Main extends Sprite
{
	private var renderer:ParticleSystemRenderer;
	private var particles:Map<Point, ParticleSystem> = new Map<Point, ParticleSystem>();	
	
	public function new()
	{
		super();
		
		renderer = DefaultParticleRenderer.createInstance();
		
		var width:Float = Lib.current.stage.stageWidth;
		var height:Float = Lib.current.stage.stageHeight;
		
		for (i in 0...4)
		{
			var point:Point = new Point(Math.random() * width, Math.random() * height);
			var ps:ParticleSystem = ParticleLoader.load("particles/particle.pex");
			particles.set(point, ps);
			renderer.addParticleSystem(ps);
		}

		addChild(cast renderer);

		addEventListener(Event.ENTER_FRAME, onEnterFrame);
	}
	
	function onEnterFrame(e:Event):Void 
	{
		var iter:Iterator<Point> = particles.keys();
		while(iter.hasNext())
		{
			var point:Point = iter.next();
			particles.get(point).emit(point.x, point.y);
		}
	}
}

The results for FPS were approximately:
Windows = 60
Neko = 10
Flash = 60
Html5 = 150
Android = 10
But looking inside Restorer code if I use this flag
<define name="zameparticles_use_sprite_visibility" />
anything changed.

But just looking around I saw that DefaultParticleRenderer for Android, Neko and Windows is SpritesParticleRenderer but if you change it to TilemapParticleRenderer it goes much faster.

Maybe it would be a good idea to change the default renderer.

I am using
Lime 7.7.0
openfl 9.0.2
haxe 4.1.4

Thank you for the share!
