var context3D:Context3D;

var stage3D:Stage3D = stage.stage3Ds[0];
stage3D.addEventListener(Event.CONTEXT3D_CREATE, onContext3DCreate);
stage3D.requestContext3D(Context3DRenderMode.AUTO);

function onContext3DCreate(event:Event):void {
    context3D = stage3D.context3D;
    trace("GPU Renderer: " + context3D.driverInfo);
