XNA 丢帧

Question

我读到，为了提高性能，可以删除帧（60 fps 之外）以允许与时间一致的更新，而不是减慢整个游戏的速度。我认为这只是指绘制而不是更新/后缓冲......？

也就是说，跳帧可能会导致更多的抖动动作，但不会使游戏变得不切实际。有谁对如何实现这一点有任何建议以及是否建议这样做？

Answer 1

如果您将 IsFixedTime 设置为 true，xna 游戏类会自动管理该时间。

来自 MSDN：

If IsFixedTimeStep is false, 
   Update and Draw will be called sequentially as often as possible. 
If IsFixedTimeStep is true, 
   Update will be called at the interval specified in TargetElapsedTime, 
   while Draw will continue to be called as often as possible. 
   If Draw is not called, IsRunningSlowly will be set to true.
