well the pyra mcu isn't doing any processing as far as i can tell. that double line corresponds well to the given spec of 3600fps in the datasheet.
so if bumping the pyra consistently gives an initial response that slopes up over a few ms, probably confirms sensor smoothing... which is weird since 3305's max dpi is 3200 which isn't really high
too busy to check forums as regularly
pm me if i forget to respond
