坏消息：在相同的Mac OS X配置上我得到相同的结果。好消息：
isAccelerated()是的。
System.out.println("BufferStrategy accelerated? " + bufferStrategy .getCapabilities().getFrontBufferCapabilities().isAccelerated());代替
Canvas和
BufferStrategy我只用
newJPanel(true)。
附录：例如，
import java.awt.Color;import java.awt.Dimension;import java.awt.EventQueue;import java.awt.Graphics;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.util.Random;import javax.swing.Jframe;import javax.swing.JPanel;import javax.swing.Timer;public class NewTest extends JPanel implements ActionListener, Runnable { private Random r = new Random(); private Timer t = new Timer(10, this); public static void main(String[] args) { EventQueue.invokeLater(new NewTest()); } @Override public void run() { Jframe f = new Jframe("NewTest"); f.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); f.add(this); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); t.start(); } public NewTest() { super(true); this.setPreferredSize(new Dimension(640, 480)); } @Override protected void paintComponent(Graphics g) { int width = this.getWidth(); int height = this.getHeight(); g.setColor(Color.BLACK); g.fillRect(0, 0, width, height); g.setColor(Color.RED); g.drawLine(r.nextInt(width), r.nextInt(height), r.nextInt(width), r.nextInt(height)); } @Override public void actionPerformed(ActionEvent e) { this.repaint(); }}
