在60 FPS .NET重绘？ [英] .NET Redraw at 60 FPS?

问题描述

我有在OpenGL上下文窗口中运行一些动画，所以我需要不断地重新绘制。所以，我想出了下面的代码：

I've got some animations running in an OpenGL context window, so I need to constantly redraw it. So I came up with the following code:

    void InitializeRedrawTimer()
    {
        var timer = new Timer();
        timer.Interval = 1000 / 60;
        timer.Tick += new EventHandler(timer_Tick);
        timer.Start();
    }

    void timer_Tick(object sender, EventArgs e)
    {
        glWin.Draw();
    }

这只是给了我40 FPS虽然。但是，如果我时间间隔设置为1毫秒，我能达到60所以哪里的其他20毫秒去了？是，仅仅由于定时器或什么的精度差？如果我想让我的程序运行尽可能快，是有办法，不断调用draw FUNC？

That only gives me 40 FPS though. If I set the interval to 1 ms however, I can achieve 60. So where did the other 20 ms go? Is that just due to poor accuracy of the timer or what? What if I wanted to let my program run as fast as possible, is there a way to continuously call the draw func?

推荐答案

你可以尝试实现游戏循环。

You could try implementing a game loop.

以下链接介绍了一个使用应用程序的空闲事件。这可能是使用的。你可以简单地进行一点时间测试或睡眠慢下来到你所需的帧。尝试使用System.Diagnostics.StopWatch类最精确的计时器。

This link describes one that uses the application's Idle event. It may be of use. You can simply perform a little time test or sleep to slow it down to your required fps. Try using the System.Diagnostics.StopWatch class for the most accurate timer.

我希望这有助于一点。
