JOGL speed

I have a problem. I have a program with a few triangles rotating… very slow. How can i do that jogl fullscreen uses hardware acceleration? (i dont know if is used).

I have a ati radeon 9200, and i tried with default GLCapabilities, and with:

GLCapabilities cap=new GLCapabilities();

    cap.setHardwareAccelerated(true);
    cap.setDoubleBuffered(true);          canvas=GLDrawableFactory.getFactory().createGLCanvas(cap);

, but in fullscreen it is very slow.

PD: In a small window this is very fast, but a game is usually in fullscreen mode.

Thx for reply

Can you print out the result of glGetString(GL_VENDOR), GL_VERSION, and GL_RENDERER in both windowed mode and fullscreen mode?

What operating system are you running on?

With this code (fullscreen mode):

System.out.println(this.getGL().glGetString(GL.GL_VENDOR));
System.out.println(this.getGL().glGetString(GL.GL_VERSION));
System.out.println(this.getGL().glGetString(GL.GL_RENDERER));

out strings are:

Microsoft Corporation
1.1.0
GDI Generic

if i put windowed mode, out strings are:

Microsoft Corporation
1.1.0
GDI Generic

the same. is it normal that jogl uses GDI Generic as renderer? Thx for reply.

Wow, its great!, it run very fast now!. When i did see your post (GL_VENDOR, GL_RENDERER…) i begin to think. I have changed the opengl configuration of my videocard, from 16bits to 24bits, and now it run very well!. (Java3D crash with 24bits… JOGL whit 16bits with a ati radeon 9200)

Thx for your help. Your post has been very usefull for me. Thank you very much! :smiley:
