C++，CPU使用率过高
问题描述：
我的游戏使用的CPU的50％以上。我找到了减少CPU为40-50％的方法，但我找不到任何其他方式来减少它。我试图使用Code分析器事件探查器，但是在使用我的cpu的代码中，它并没有给我提供任何好的信息。
这里是我的代码

我不知道有关分析Windows代码，但是你的程序是如此的小，简单的（绝对术语 - 在stackoverflow上阅读很多），你可以很容易地手动测试它。我Google了以下功能：
LARGE_INTEGER from; LARGE_INTEGER to; QueryPerformanceCounter (&from); // do stuff QueryPerformanceCounter (&to); LARGE_INTEGER elapsed = to - from; LARGE_INTEGER hertz; QueryPerformanceFrecuency (&hertz);
使用你的程序所在可能会花时间去细化定时器的位置，在缓慢的代码下钻了解。

真的吗？我无法在那里得到答案吗？ – Ramilol 2010-08-25 04:11:25
Stack Overflow的工作方式使您最好只发布一次问题，如果您没有得到令人满意的答案，请尝试编辑您的问题以包含发布更好答案所需的详细信息。人们对你的问题发表了评论，给你提出建议，并告诉你它一次编写的代码太多。 – zneak 2010-08-25 04:22:40
