Hello, i am having a bit of an issue making a snow flake effect that doesn’t take up much cpu performance, this may be a bit of an oxymoron but i was hoping to see if anyone knew of a smart way of achiving this.

right now the animation only peaks at 18% on my dual core amd x2, but hits 100% hard on most computers i test on. ☹

here is my current example --\> [http://www.uncommonsense.com/troy/babygirl/](http://www.uncommonsense.com/troy/babygirl/)

here is my current fla --\>  
[http://www.uncommonsense.com/troy/babygirl/holidayAdventure05.zip](http://www.uncommonsense.com/troy/babygirl/holidayAdventure05.fla)

here is my code for the snow flakes --\>

```auto

//-------------------------------------------------------------------------------------------------
//SNOW CONTROLLER
//-------------------------------------------------------------------------------------------------
var j:Number = 0;
var i:Number = 0;
var t:Number = 0;
var rad:Number = 0;
var snowFlakeCount:Number = 0;
var snowFlakes:Array = new Array();
//CHANGEABLE VARS
var snowFlakeLimit:Number = 5;
//
this.onEnterFrame = snowController;
function snowController():Void {
    //
    for (j=0; j<snowFlakes.length; j++) {
        var movieClip = snowFlakes[j];
        movieClip._y += movieClip.i;
        movieClip._rotation += movieClip.i;
        movieClip.rad += (movieClip.k/180)*Math.PI;
        movieClip._x -= Math.cos(movieClip.rad);
        if (movieClip._y>Stage.height-50) {
            movieClip.removeMovieClip();
            snowFlakes.splice(j, 1);
            snowFlakeCount--;
        }
    }
    //   
    var randomNum = Math.round(Math.random()*25);
    if (randomNum == 25) {
        if (snowFlakeCount<snowFlakeLimit) {
            i = 2+Math.random()*2;
            k = -Math.PI+Math.random()*Math.PI;
            snowFlakeCount++;
            t++;
            if (t == 100) {
                t = 1;
            }
            var randomNum = (Math.round(Math.random()*3))+1;
            if (randomNum == 4) {
                randomNum = (Math.round(Math.random()*3))+1;
            }
            var movieClip = eval("snowflake0"+randomNum+"_mov");
            var snowflake = movieClip.attachMovie("snowFlake_lib", "snowFlake"+t, t);
            snowflake._x = Math.random()*Stage.width;
            snowflake._y = -100;
            snowflake.i = i;
            snowflake.k = k;
            snowflake.rad = rad;
            snowflake._xscale = snowflake._yscale=(Math.round(Math.random()*150))+51;
            snowFlakes.push(snowflake);
        }
    }
}
