C# 大量CPU利用率-XNA游戏循环
我用ANTS profiler浏览了我的游戏，看看是什么导致了我的FPS大幅下降，我发现这与玩家的动作有关。请看，每当我的播放机移动时，一个名为C# 大量CPU利用率-XNA游戏循环,c#,performance,profiling,lag,frame-rate,C#,Performance,Profiling,Lag,Frame Rate,我用ANTS profiler浏览了我的游戏，看看是什么导致了我的FPS大幅下降，我发现这与玩家的动作有关。请看，每当我的播放机移动时，一个名为Microsoft.Win32.SafeNativeMethods.QueryPerformanceCounter的东西就会占用我大约75%的CPU。根据ANTS的说法，它链接到System.Diagnostics.Stopwatch.GetTimestamp。以下是探查器结果的屏幕截图： 这是我所有的代码： Player.cs namespace I
