I’m having trouble getting hardware acceleration to work with grc’s
graphical sinks. With the regular sinks the refresh rate is always
and sluggish until it eventually locks up completely. And when I tried
OpenGL sinks it turned out they’re even slower than the regulars,
the FFT Sink in which even the buttons can’t be pressed with most my
configurations, though I have to mention that with the OpenGL version
waveform in the middle of the sink’s window is drawn fine, it’s just
the buttons are unclickable. That’s when I figured it’s a graphics issue
not due to the cpu. All the other graphically intensive programs work
on this machine, so I know I got the driver properly configured.
Anyone having the same issues?
Any help is appreciated
P.S. - My configuration: I’m using the latest gnuradio source code along
with a USRP2 and a WBX board, decimation is at 4, the FFT Sink’s bin
set at 2048 and its sampling rate is at 1,000,000. The computer is a
Thinkpad X61s with a Core2Duo 1.6GHz processor and an Intel GM965
