Time Step understanding

[DuffCola]

Hello.
I read the sfml game development book.
I amcurrently at the time step chapter.

void run()
{
    renderWindow = new RenderWindow(sf::VideoMode(800, 600), "Test", sf::Style::Default);
    //  renderWindow.setFramerateLimit(60);             //
    //  renderWindow.setVerticalSyncEnabled(true);   //
    sf::Clock deltaTime;

    while(renderWindow.isOpen())
    {
        sf::Event events;
        while(renderWindow.pollEvent(events))
        {
            handleEvents(events);
        }
        update(deltaTime.restart());
        render(renderWindow);
    }

}

 

What going different, if I set the frame rate Limit oder/and ther cSynchr ?
Whats the best Time Step method ?

setFramerateLimit() is useful for simple cases, but it's not very accurate. setVerticalSyncEnabled() can be used in addition to our time step method, to adapt the graphic framerate to the monitor's frequency.

There is a short section about these topics on page 24.
