see sig for specs
i get "good" FRs but.. also "it depends"
yeah, i get 60fps over vegas ----- if i'm over ~3k ft MSL
if i get lower - i get stuttering ---- in fact, i'm kinda fine if i just keep looking straight ahead
but zooming in just-a-bit.. and i get stutters
low-alt, looking out to the sides, zoom in 1/4 to 1/2 way - stutters
zoom in all the way - not so much a problem
so....... i wish i didn't have ANY problems whatsoever, but i can't actually say that
