LWJGL uses wrong graphics card

Hi

I’m trying to learn modern OpenGL using LWJGL, but it seems that it uses the wrong graphics card.
By using GPU Caps Viewer I get the info that my main card has OpenGL 4.2.

But creating a Display gives “Could not create context (WGL_ARB_create_context)”. on “Display.create(pixelFormat, contextAtrributes);”
From this example: http://www.lwjgl.org/wiki/index.php?title=Version_selection

I did a simple program trying to confirm the version:

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.ContextCapabilities;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GLContext;

public class OldOpenGL {
	public void start() {
		try {
			Display.setDisplayMode(new DisplayMode(800, 600));
			Display.create();
			version();
		} catch (LWJGLException e) {
			e.printStackTrace();
			System.exit(0);
		}
		while (!Display.isCloseRequested()) {
			Display.update();
		}
		Display.destroy();
	}

	public static void main(String[] argv) {
		OldOpenGL displayExample = new OldOpenGL();
		displayExample.start();
	}
	public void version()
	{
		ContextCapabilities c =GLContext.getCapabilities();
		if(c.GL_ARB_compatibility)
		{
			System.out.println("ARB");
		}
		if(c.OpenGL32)
		{
			System.out.println("3.2!");
		}
		else if(c.OpenGL20) {
			System.out.println("2.0");
		}
		else
		{
			System.out.println("No OpenGL");
		}

	}
}

And it prints out “ARB” and “2.0”.
So my guess is that it uses the graphics on the CPU.

It has:
Intel HD Graphics 3000 and NVS 4200M (and GPS Caps Viewer says the both have OpenGL 4.2)

I change so the Nvidia settings so java uses the performance-mode, but still no luck.

Any sugestions?

Add both JRE and JDX .exe files to dedicated graphics usage in your GPU settings. This fully works for me, remember to FULLY shutdown all Java processes.

I didn’t make it work with adding java and javaw to the list. But if i (system wide) changed it to performance with the Nvidia Card then it work.

Anybody know any way to make the jar demand high performance?
