How to learn the identity of the graphics card?

I see. You just want to be able to detect the GPU on a system to
determine which rendering techniques to use your application.
Take a look at D3DPipeline.findDefaultResourceFactory() and
ES2Pipeline.findDefaultResourceFactory(). You should be able make the
needed change to pass the GPU information (in printDriverInformation())
back to your application. You can follow the pattern of is3DSupported()
in the class.
If you like you might want to file a JIRA for this enhancement request
so that you don't have to make similar patch for future JavaFX releases.
