Comment (by bizzehdee):

 i want to use mmx2 or 3dnow because i usually get 70fps on x264, with
 3dnow or mmx2 enabled in sws, i get around 120fps, though i dont know if
 thats because its broke, or if its because thats what the optimisations
 do.

 but here is the output from the minimal configure line i posted before:
