Hi Jim,

please checkout the small app on Github: https://github.com/tobium/JavaFXPerformanceTest

Mac OS X: 10.10.4
Mac Book Pro Retina (Late 2012), Intel HD Graphics 4000 1024 MB, 8 GB RAM, i7 2,6Ghz
Java FX 1.8.0_60


FPS: Mac and Windows: 60 FPS
CPU usage: Mac: 25-80%, Windows: 0-3%


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?
