So here is the code of the test that shows how much slower Windows 64bit captive is when compared to Windows 32bit captive: package { import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; import flash.text.TextField; import flash.text.TextFormat; import flash.utils.getTimer; import flash.utils.setTimeout; [SWF(frameRate="60", width="1280", height="720", backgroundColor="0x000000")] public class Windows64BitPerformanceTest extends Sprite { private static var i:int = 0; private static var c:int = 0; private static var m:int = 0; private static var f:int = 0; private static const ITERATION_COUNT:uint = 500000000; private var _logTextField:TextField; private var _logTextFormat:TextFormat; public function Windows64BitPerformanceTest() { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; this.loaderInfo.addEventListener(Event.COMPLETE, this.loaderInfoLoadCompleteEventHandler); } protected function loaderInfoLoadCompleteEventHandler(event:Event):void { _logTextFormat = new TextFormat('Verdana', 40, 0xFFFFFF, true, false, false, null, null, 'center'); _logTextField = new TextField(); _logTextField.setTextFormat(_logTextFormat); _logTextField.defaultTextFormat = _logTextFormat; _logTextField.width = stage.stageWidth; _logTextField.y = stage.stageHeight / 2; addChild(_logTextField); setTimeout(runTest, 1000); } private function runTest():void { var time:int = getTimer(); for(i = 0; i <= ITERATION_COUNT; i++) { f += incrementC(); f += incrementM(); } _logTextField.appendText('Completed in ' + (getTimer() - time).toString() + ' milliseconds.'); } private function incrementC():int { if(isModule2(c) == 1) { c += 1; } else { c += 2; } return c; } private function incrementM():int { if(isModule2(m) == 1) { m += 1; } else { m += 2; } return m; } private function isModule2(v:int):int { if(v % 2 == 0) { return 1; } else { return 0; } } } } On my machine this test completes in around 15 seconds for 32bit but for 64bit it took 43 seconds so this difference is very huge. This test was run on Windows 10 with Intel i7 CPU. This was tested with latest AIR 32 SDK. Also here are the download link for executable files of this test for both 32bit and 64bit so guys please test it if you have AMD CPU to see if there is difference: http://bit.do/eUCzx
