好的，我正在创建一个游戏，但它使用了太多的 CPU，但没有使用太多的内存。 cpu确实增加和减少。我的游戏中有太多计时器，当我不再使用它时我会关闭计时器，所以这应该会导致问题，但我认为导致问题的原因是我的消息队列中有太多消息。我有 5 个月大的新笔记本电脑，它的 CPU 很高。它使用了我 40% 的 CPU。有没有办法减少它，因为当它达到 40% 时，游戏速度会变慢。
这是我的代码

return (INT_PTR)TRUE;
case WM_COMMAND:
if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL)
{
EndDialog(hDlg, LOWORD(wParam));
return (INT_PTR)TRUE;
}
break;
}
return (INT_PTR)FALSE;
}
有什么想法吗？
