Only Integrated GPU is used

I have a GLCanvas in a JFrame.
When I run the application, the integrated GPU works only, the dedicated GPU is doing nothing.

I suspect it is because my window is not a true fullscreen window even if I set the size of it to my screen size or if I use device.setFullScreenWindow(frame).
I guess if I could set it to true fullscreen, the dedicated GPU would take over.

Anyone knows what I could do?
Maybe to use GLWindow instead of GLCanvas?

I was planning to use Swing, but I guess being able to use the better GPU would be the priority.

Hello

We don't expose any vendor specific extension allowing to modify the GPU affinity, you have to force the use of the high performance profile by yourself in the setup of your laptop. We don't support Optimus and similar mechanisms.

If the automated load-switching is not supported, (Which it sounds like it is not)

You can force selection on launch using a native launcher via JNI (see https://www.developer.com/java/data/how-to-create-a-jvm-instance-in-jni.html ) and export certain C-language symbols.

See the following for the relevant symbols for the major card manufactureres:

Note: This only works if the user has the dedicated GPU enabled (It can often be turned off in BIOS or system configuration settings)

It also means that your application will *Only* Use the dedicated GPU - it will not seamlessly switch for power conservation.
