我使用Flash CS4和测试应用程序时，我的帧速率的变化，因为它是编程这样做。当我尝试运行在浏览器应用程序（试过火狐4，歌剧10.5和IE 8）的帧速率不会改变。

I am using Flash CS4 and when testing my application my frame rate changes as it is programmed to do so. When I try to run the application in a browser (tried Firefox 4, Opera 10.5 and IE 8) the frame rate does not change.

为什么帧速率不会改变？如何解决呢？

Why does the frame-rate not change? How do I fix it?

推荐答案

最新的Flash Player被限制在最高60fps的，不管你用什么数字来设置帧率。这可能是一个问题......但如果​​屏幕上的对象正在放缓没有什么改变帧率来获得。这意味着，你的SWF没有得到很好的优化，玩家正在努力使资产。

The newest Flash Players are capped at a maximum of 60fps, no matter what number you use to set the framerate. That could be one issue... But if objects on the screen are slowing down there's nothing to be gained by changing the framerate. It means that your swf isn't well optimized, and the player is struggling to render the assets.
