Java 2D performacje on fullscreen mode

Cranegger · February 23, 2008, 4:32pm

I wrote my own game engine based on Java 2D API. I run some demos on fullscreen mode on my 22" monitor but I’m not glad because of performance. Why is performance so low?

I would recommend you try a hardware acceleration binding like LWJGL or JOGL that allow you to use OpenGL/DirectX, this will give you much better performance and is a must for nice smooth games.

If you don’t want to learn OpenGL, you could try port it over to the Slick Library, it has OpenGL hardware acceleration and a very similar api to Java2D, this should make it easy to port your engine over. http://slick.cokeandcode.com

So nobody uses Java 2D in fullscreen games?

trembovetski · February 23, 2008, 8:12pm

You’ll need to be more specific. What jdk version, what OS, what video board.

What kind of stuff your application does?

Many use fullscreen mode for gaming and are happy with it.

Java 6 update 3
Windows XP SP2
resolution: 1680x1050 px

EDIT: and olny ~20 fps

trembovetski · February 23, 2008, 8:56pm

What kind of operations do you do?

Images? If so, translucent, bitmask?
antialiased rendering? Shapes?

What do you use for double-buffering?
BufferStrategy or VolatileImage? (I suggest the former).

If you can distill your app to a simple test case, that’d be the best.

Java 6 has Direct3D pipeline enabled in full screen mode. Check that it’s
working : set J2D_TRACE_LEVEL=4 env. variable before starting
your application and post the output.

also, the upcoming 6u10 (jdk6.dev.java.net) will have a new DirectX 9 based
pipeline enabled by default in both windowed and full-screen mode. You
may want to try it out.

Thanks,
Dmitri

It’s everything what I draw:


        g.clearRect(0, 0, size.width, size.height);
        
        // Tło
        int width = background.getWidth(null);
        int height = background.getHeight(null);
        int x = 0;
        int y = 0;
        
        int rowCount = TileSet.pixelsToTiles(size.height, bgSize.height) + 1;
        int columnCount = TileSet.pixelsToTiles(size.width, bgSize.width) + 1;
        
        for (int row = 0; row < rowCount; row++, y += height)
        {
            for (int column = 0; column < columnCount; column++, x += width)
                g.drawImage(background, x, y, null);
            
            x = 0;
        }
        
        // Kafelki
        tileSet.draw(g, size, point);
        
        // Duszki
        player.draw(g, point);
        monster.draw(g, point);
        
        // FPS
        g.drawString("FPS: " + getFPS(), 0, (int)g.getFont().getStringBounds("K", g.getFontRenderContext()).getHeight());

I don’t use any antialiasing or something like that…
I use BufferStrategy.

How can I do this?

trembovetski · February 23, 2008, 9:14pm

What kind are your images? BufferedImages? How do you load them?

How can I do this?

Run cmd.exe, then:
#> cd
#> set J2D_TRACE_LEVEL=4
#> java -jar YourApp.jar

This will print out a bunch of debug information on the console.

Also, could you try this:
#> java -Dsun.java2d.trace=log -jar YourApp.jar > log 2>&1

Let it run for a few seconds, then quit the app.

This last command will trace the rendering primitives.
If you could post a representative piece out of that, it’d help
diagnosing the issue.

The code that you posted seem fine - it should work just fine.

return new ImageIcon(fileName).getImage();

Yuck.

Try ImageIO.

trembovetski · February 24, 2008, 2:38am

Try ImageIO.

In theory it shouldn’t matter that much although it certainly is
wasteful (pulling swing just for loading images).

Are those images 1-bit transparent, translucent? Gifs, pngs, jpegs?
There used to be a bug where some kind of loaded images weren’t
being accelerated.

Also, could you add the output with -Dsun.java2d.trace=log?

Thanks,
Dmitri

They’re pngs. Some of them are transparent.

trembovetski · February 25, 2008, 2:11am

You seem to be getting full hw acceleration, I’m not sure why it
only gives you 20fps.

What video board do you have?

Also, could you please set this property: -Dsun.java2d.trace=count (note - count, not log)
let it run for 10-15 seconds and quit. It will print out the summary of
which primitives were used.

Thanks,

Before anyone else googles around… with “WinFast A340” he means a GeForce FX 5200.

trembovetski · February 25, 2008, 10:10pm

Yeah, I have one of those here. They aren’t speed demons for sure.
But I would have expected to get something more decent out of it.

Have you tried changing the display mode to something like
1200x1024? Just to see what kind of improvement you’d get?

Dmitri

Cranegger · February 26, 2008, 3:49pm

I can’t set this resolution. But when I set it on 1024x768 I get 30 FPS.
