That's completely the key point: RAF provides a simple way to get the
best of the display you have (and prevents you from oversampling, which
is pretty cool BTW ;) ). 

The most important feature we should ask to RAF implementers is
stability, in order to miss no frames when presenting something at 60
Hz (or whatever the native frame rate it is).

Best,
