Is there a way to detect if Java FX is using hardware acceleration?

Question

And related to that, is there a way to force Java FX to use hardware acceleration and bomb if it is unable to?

Answer 1

Just found out:

You can run with -Dprism.verbose=true which will print what graphics pipeline it uses. "sw" or "j2d" for software and "d3d" or "es2" for hardware accelerated.

Answer 2

You can also try this hack

@SuppressWarnings("restriction")
static String getCurrentGraphicsPipeline() {
    return com.sun.prism.GraphicsPipeline.getPipeline().getClass().getName();
}

If you get back "com.sun.prism.sw.SWPipeline" then you're using software acceleration. All other values will mean that probably some form of hardware acceleration is being used.

Answer 3

If you are using eclipse as IDE, then you need to pass these VM arguments. You can add these VM arguments in the run Configurations.

Put these arguments there: -Dprism.verbose=true
