What is the best way to get a high frame rate in a JavaFX application?

[Kevin Rushforth]

Yes, I think that's the best advice for now.

Really, though, a good RFE would be to provide a way to adapt to the 
refresh rate of the monitor when vsync is being used. That's really the 
point of doing vsync in the first place.
