Lately I've been displaying four values:

1) The "frame rate" of the previous frame (i.e. the reciprocal of the frame
time)

2) The "frame rate" of the slowest frame in the last second

3) The "frame rate" of the fastest frame in the last second

4) The average frame rate over the last second

You need to store recent frame times in a FIFO to be able to compute these
stats, but I find them useful for  diagnosing hitches and sync effects.
