JavaFX graphic performance slow on Mac? Clock app

[Tobias Bley]

Hi Jim,

that’s very interesting. BTW: Where do I get the ES2 implementation for Windows?

I will remove all extern dependencies in the the project.

Best regards,
Tobi

I created a little clock app which uses between 25% and 80% cpu usage. But what’s the reason for? I though JavaFX rendering pipeline works on the graphic device? So why there is such a traffic on the CPU?
