为什么我的 MonoGame 简单应用程序滞后？

Question

我用 MonoGame API 为 Android 编写了我的简单游戏。我触摸应用程序运行相当不错的性能，但可以肯定的是，我制作了简单的 FPS 计数器，结果是 54-60 fps，我并不满意，所以我将我的 fps 计数器移动到 MonoGame 模板以查看部分我的代码导致了延迟，我发现即使是几乎清晰的应用程序运行也具有 54-60 fps 的相同速度。问题不是来自 GC，因为没有要收集的垃圾。有没有办法避免这些滞后？这是应用程序：

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace perf_test
{
    public class FRAPS
    {
        float fps_from;
        int fps;
        public int fps_toshow;

        public float in_Secs;


        public void add_frame()
        {
            fps_from += in_Secs;
            if (fps_from > 1)
            {
                fps_toshow = fps;
                fps = 0;
                fps_from = 0;
            }
            fps++;
        }
    }
    public class numbers

             {

                 {

                 }
                else break;
            }
        }
        nuu -= num1 * 10;
        for (int i = 0; i < 10; i++)

        Numb.load(Content);
    }

    protected override void UnloadContent()
    {
    }

    protected override void Update(GameTime gameTime)
    {
        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
            Exit();
        base.Update(gameTime);
    }

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();
        fraps.in_Secs = (float)gameTime.ElapsedGameTime.TotalSeconds;
        fraps.add_frame();
        Numb.number = fraps.fps_toshow;
        Numb.update();
        Numb.draw();
        spriteBatch.End();

        base.Draw(gameTime);
    }
}

}

设置

IsFixedTimeStep = false;

在您的 Game1 构造函数中。 XNA/Monogame 自动将您限制在 60 FPS。
