Something else I've noticed is if the lag is too bad, jumping doesn't help and it can be a hassle to grab wings just to take them off when ya get to the top. As difficult as it's proven to be, running up the ramp while jumping AND looking at the sky does in fact help. Just be sure not to launch yourself off the edge!
If it is a lag induced problem, try turning your water reflections off, as Fluorite is one giant island.
To do so: esc>options>video>water reflection then just uncheck it!
Water lag is a major cause of most lag problems, so you can use this little trick wherever you are.
