There's a distinct reason there's a 60fps cap. Most humans can only discern 1/6th of that resolution. The UI atom has typically been 100msec. Larger feels laggy. Smaller's snappy, but the event loops on many machines until recently couldn't give it to you any better than 100msec. Same goes for framerate. You can't discern past 60fps as anything more than flicker unless you've trained yourself and then it's something like 80 or so fps as that threshold.
