Question

Alright, i’m making a small game, and I need to limit my FPS, because, when I play on my really fast computer, I have around 850 FPS, and the game will go like, REALLY fast, and when I switch to my older computer, it goes alot slower, so I will need to limit my FPS to get this right. How do I limit my FPS?
My main game loop:

    public void startGame(){
    initialize();
    while(true){
        drawScreen();
        drawBuffer();
        plyMove();

        //FPS counter
        now=System.currentTimeMillis(); 
        framesCount++; 
        if(now-framesTimer>1000){
            framesTimer=now; 
            framesCountAvg=framesCount; 
            framesCount=0; 
        }

        try{
            Thread.sleep(14);
        }catch(Exception ex){}
    }
}

How I draw the screen, and draw all of the other things, players, the ball, etc.
The game is a pong remake, btw.

    public void drawBuffer(){
    Graphics2D g = buffer.createGraphics();
    g.setColor(Color.BLACK);
    g.fillRect(0,0,600,500);
    g.setColor(Color.GREEN);
    g.fillRect(ply1.getX(),ply1.getY(),ply1.getWidth(),ply1.getHeight());
    g.setColor(Color.RED);
    g.fillRect(ply2.getX(),ply2.getY(),ply2.getWidth(),ply2.getHeight());
    g.setColor(Color.WHITE);
    g.fillOval(ball1.getX(),ball1.getY(),ball1.getWidth(),ball1.getHeight());
    g.drawString("" + framesCountAvg,10,10);
}

public void drawScreen(){
    Graphics2D g = (Graphics2D)this.getGraphics();
    g.drawImage(buffer,0,0,this);
    Toolkit.getDefaultToolkit().sync();
    g.dispose();
}

It sounds like your display it tied to your game engine. Make sure the two are disconnected. You want the game playing at the same speed no matter what the framerate is. If your fast computer repaints the screen faster that is ok if the engine is causing the game to play at a constant speed.
