The waterfall rate is exactly like the fft rate: a decimation is
computed so that the actual rate of fft frames per second (from the log
power fft block) is approximately the given fft rate.
The reason for adding a new preference is that the CPU and graphics
requirements are different for the

OK. What are the units, and how would it behave?

I think we need another preference parameter for the "waterfall rate". It
should not be the same rate as the fft rate.
Howabout "waterfall_rate"?

The flickering issue is fixed in the trunk r9333.
Certain machines defaulted to "single" buffering. Double buffering is
now explicitly enabled.

You can lower the frame rate from the default of 30 by adding the
following line(s) to your config.conf:
[wxgui]
fft_rate=15 (..
Hi,
1) Great Work.
2) I think screen refresh (drawing times) is too high (on my system) that
leads to flickering.
3) Compiling a fresh trunk copy (rev 9311) on my C2D running Ubuntu 8.04,
the running of usrp_fft.py for the first time leads to the following error :

Just tested the opengl implementation... Rocks hard ! Update times are
really up on my C2D 2.4G E4600 / 2GB / Intel 82G33/G31 / Ubuntu Hardy.
Had to do a "make clean" also, since it was reporting some top_block4dump
error while running any GR code. Probably a lone case. In Ubuntu, you can

Awesome. 1000% Performance improvement under OSX.
Waterfall was completely unusable for me before. Thanks
