Re: [Discuss-gnuradio] gr-fosphor : New RTSA-like visualization block for GNURadio using GPU acceleration

Good call. I applied the 4 patches and now I can run osmocom_fft with
the -F option succesfully.
--------
$ osmocom_fft -F -a "fcd=1"

Using FUNcube Dongle V2.0 (hw:3)
Opened: hw:3

However, it seems to be quite laggy, with 'chunks' of 'water' 'falling'
at about 1 second intervals and not flowing smoothly.

Looks nice though :)

Cheers,
