SWFObject Slowdown ?

Hi,

I have this code in my HTML:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="100%" height="100%" id="fullscreen_ex_8" align="middle">
  <param name="allowScriptAccess" value="sameDomain" />
  <param name="movie" value="g3.swf" />
  <param name="quality" value="high" />
  <param name="scale" value="noscale" />
  <param name="bgcolor" value="#000000" />
  <embed src="g3.swf" wmode="gpu" quality="high" scale="noscale" bgcolor="#000000" width="100%" height="100%" name="fullscreen_ex_8" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>


I converted it to use with SWFOBJECT:

<script type="text/javascript">
        // <![CDATA[
            var so = new SWFObject(g3.swf', 'g3', '100%', '100%', '8', '#000000');
            so.useExpressInstall('swfobject/expressinstall.swf');
            so.addParam('menu', 'false');
                  so.addParam('scale', 'noscale');
                  so.addParam('wmode', 'gpu');
                  so.addParam('quality', 'high');
                  so.addParam('allowScriptAccess', 'sameDomain');
                  
            so.write('content');
        // ]]>
</script>



both work, but there is a significant performance lose with the swfobject version, somehow it is passing some obscure parameters to flash player that cause things to degrade.

my SWF has a lot of screen movement and thus is sensitive to performance

thank you

My be a cut&paste error, but there is a missing quote  in the first line before g3.swf.
Anyway I don't think it's related with your problem.

What i can see is that in your OBJECT there isn't the wmode parameter, whil in your EMBED or jscript is there.
May be you're testing you app in IE that uses the OBJECT...

I need to put it in the object too ?

but it works much faster with the object version, and the swfobject version has the wmode parameter...

There are 3 wmode values : Window, Opaque and Transparent.
In your code you are using a "gpu" value, which is not valid.

I think you can try to remove it from the swobject, and biyik, as of version 10, this is a valid value, but the optimization in somes cases can slow down the execution of the swf.

Just my 2 cents.
