How can I Edit preferences performance use Graphics Processor option through the jsx script

Question

Hi I need to check and access the Edit>preferences>performance>use Graphics Processor option setting through the script. i cant find it in the object domain, I have the following to check the current state:
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID('capp'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
var openglEnabled = executeActionGet(ref).getObjectValue (charIDToTypeID('CchP')).getBoolean (stringIDToTypeID('openglEnabled'));
alert( openglEnabled );
but then i am unable to set the value using this:
var openglEnabled = executeActionGet(ref).getObjectValue (charIDToTypeID('CchP')).putBoolean (stringIDToTypeID('openglEnabled'));
I tried using a recorded action but that doesnt work. Any recommendations?

If you load the scriptlisener plug-in when you set  your preference to enable your GPU it will record the code you need.  The Code I posted to your thread in the scripting forum the other day.
// =======================================================
var idsetd = charIDToTypeID( "setd" );
    var desc29 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref19 = new ActionReference();
        var idPrpr = charIDToTypeID( "Prpr" );
        var idCchP = charIDToTypeID( "CchP" );
        ref19.putProperty( idPrpr, idCchP );
        var idcapp = charIDToTypeID( "capp" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref19.putEnumerated( idcapp, idOrdn, idTrgt );
    desc29.putReference( idnull, ref19 );
    var idT = charIDToTypeID( "T   " );
        var desc30 = new ActionDescriptor();
        var idMmrU = charIDToTypeID( "MmrU" );
        var idPrc = charIDToTypeID( "#Prc" );
        desc30.putUnitDouble( idMmrU, idPrc, 90.000000 );
        var idopenglEnabled = stringIDToTypeID( "openglEnabled" );
        desc30.putBoolean( idopenglEnabled, true );
    var idCchP = charIDToTypeID( "CchP" );
    desc29.putObject( idT, idCchP, desc30 );
executeAction( idsetd, desc29, DialogModes.NO );
