c ++使用太多的cpu [英] c++ using too much cpu
本文介绍了c ++使用太多的cpu的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
ok im创建一个游戏，但它使用太多的cpu，但它不使用太多的内存。 cpu增加和减少。我有太多的计时器在我的游戏，我杀了定时器，当我不再使用它，所以应该导致一个问题，但我认为导致的问题是有太多的消息在我的消息qeue。我有新的笔记本电脑是5个月大，它有一个高cpu。它使用我的cpu的大约40％。有办法减少它，因为当它达到40％的游戏减慢。

h2_lin>解决方案我的猜测是，你会不断重新分配和重绘一切，而不是简单地移动图像。我可以看到应用程序经常需要重新分配和重新绘制从头开始在系统上有瓶颈。
ok im creating a game but it uses too much cpu but it doesn't uses too much memory. the cpu does increase and decrease. i have too many timers in my game, i kill the timer when i don't use it any more so that should cause a problem but what i think that causes the problem is there is too many messages in my message qeue. i have new laptop it is 5 months old and it has a high cpu. it uses about 40% of my cpu. is there way to reduce it because when it gets to 40% the game slows down.
here is my code
