The strange thing is that when the fft's sample rate is at 25Msps which equals the USRP's bandwidth at a decimation of 4 everything works fine with the regular fft sink yet not with the OpenGL one. However when I increase the fft's sample rate to 50Msps which is 2x the USRP's bandwidth both sinks work fine. What does this mean? I'm really convinced all this is because graphics are rendered strictly through software. Does GRC even support graphics hardware acceleration? how do I configure it? -- View this message in context: http://old.nabble.com/GRC%27s-graphical-sinks-performance-issues-tp29600609p29604761.html Sent from the GnuRadio mailing list archive at Nabble.com.
