Hi there, I'm having trouble getting hardware acceleration to work with grc's graphical sinks. With the regular sinks the refresh rate is always choppy and sluggish until it eventually locks up completely. And when I tried the OpenGL sinks it turned out they're even slower than the regulars, especially 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 the waveform in the middle of the sink's window is drawn fine, it's just that the buttons are unclickable. That's when I figured it's a graphics issue and not due to the cpu. All the other graphically intensive programs work fine 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 size is 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 graphics controller.
