使用C#调用EasyHook来Hook系统API实现游戏加速，宿主进程会卡死是什么原因？如何排查？

部分代码如下：

public static double SpeedUp = 1.0;
public static int StoredRealTime = 0;
public static int StoredFakeTime = 0;
public LocalHook QueryPerformanceCounterHook = null;

private bool SetSpeedUp(double NewSpeedUp)
 {
      SpeedUp = NewSpeedUp;
      if (QueryPerformanceCounterHook == null)
      {
                QueryPerformanceCounterHook = LocalHook.Create(LocalHook.GetProcAddress("kernel32.dll", "QueryPerformanceCounter"), new QueryPerformanceCounterDelegate(QueryPerformanceCounterEx), this);
                QueryPerformanceCounterHook.ThreadACL.SetExclusiveACL(new Int32[0]);
      }
}

static bool QueryPerformanceCounterEx(out long FakeTime)
 {
        bool result;
        long RealTime = 0;
        int TickCount = timeGetTime();
        result = QueryPerformanceCounter(out RealTime);

         if (StoredRealTime == 0) // Initialize
          {
                StoredRealTime = RealTime;
                StoredFakeTime = TickCount;
         }

         FakeTime = StoredFakeTime + (long)((RealTime - StoredRealTime) * SpeedUp);

         StoredRealTime = RealTime;
         StoredFakeTime = FakeTime;
         return result;
 }

[DllImport("Winmm.dll")]
static extern int timeGetTime();

[UnmanagedFunctionPointer(CallingConvention.StdCall, CharSet = CharSet.Auto, SetLastError = true)]
delegate bool QueryPerformanceCounterDelegate(out long lpPerformanceCount);

[DllImport("kernel32.dll")]
static extern bool QueryPerformanceCounter(out long lpPerformanceCount);

没人知道吗？第一次来CSDN发帖，不会让我失望吧……

问题已解决，我自己说说吧！问题出在timeGetTime和QueryPerformanceCounter两个API函数有冲突，具体为什么我也不太清楚，但是注释掉第20行代码，初始化的StoredFakeTime用RealTime赋值就好了，希望有高手给出具体原因！
