i noticed this with blackberry... it plugs in at 59 er 58ish when you ask for 60.
chances are you will need to jackup the rate to 120 and control it with a timer based delay back down to 60. (this is a last resort if the vsync on is not pulling 60.
here is a beter question. Do you experience screen tearing at 50fps?
if not then thats probably what your hardware is set to. for blackberry its a completely different story. vsync does not work with bb and you are forced to pull it to 120 and drag it down to 60 using a timer delayed refresh to get rid of screen tearing. I think the system clock runs at a different rate and thats why it doesnt work. I think Paul seems to believe it works fine the way it is for bb but i can tell you right now that it doesnt....it tears every second.
what kinda tablet you running?
