MonoGame强制修改FPS刷新率
FPS即每秒绘制游戏的帧数，电脑上运行游戏60fps是流畅标准，低于30fps游戏会感觉到卡顿。手机则是30fps。通常情况使用MonoGame开发游戏无需强制修改FPS，让运行环境自己去判断是最佳选择!
如果非要强制修改FPS，只需要在游戏主类的构造方法中加入：
|
1 2 |
IsFixedTimeStep = true; TargetElapsedTime = new System.TimeSpan(0, 0, 0, 0, (int)System.Math.Round(1000.0f / 60.0f)); |
也可以写成
|
1 |
TargetElapsedTime = System.TimeSpan.FromMilliseconds(System.Math.Round(1000.0f / 60.0f)); |
也可以直接写一个值
|
1 |
TargetElapsedTime = System.TimeSpan.FromMilliseconds(16.666); |
TargetElapsedTime表示执行一帧所需要的时间
