Problem with OpenGL extensions

OpenGL Development JOGL Development
#1

Hi,
I’m new into JOGL. I’m trying to run the jogl demos which use ARB_vertex_program, Pbuffer, etc, but when I run them, it says that it’s unable to initialize the extension. I’m using WinXP and a ATI RADEON 9600SE. I’ve installed the latest drivers.

With the gears demo I get the following information:

INIT GL IS: net.java.games.jogl.impl.windows.WindowsGLImpl
GL_VENDOR: Microsoft Corporation
GL_RENDERER: GDI Generic
GL_VERSION: 1.1.0

Is there a way to correct this, apart from using another videocard?

Thanks!

The OS gives you the software-renderer (GDI Generic), it’s not using your gfx-card for any hardware acceleration.

Something went wrong while installing your drivers. I know this is not very helpful, but at least you know what the problem is.

You probably get horrible performance when running (OpenGL) 3d-games. How speedy are DirectX apps for you?

Thanks.I will have fun trying to solve this.

With the SpaceInvaders demo I get 200fps with Java2D and “only” 50fps with JOGL… ::slight_smile:

Are you using the latest version of JOGL? What does java -Djogl.verbose demos.printext.PrintExt report?
