So, you think the penalty of processing in the stack, outweighs the performance gained by having duplicate streams? You do realise they are being processed in parallel in the stack??? By the time you would start the copy, my modified DMA would be ready under all scenarios. Regards, Mark

Marcus, I have run some tests and it looks like the WX GUI FFT Sink stops responding with any settings above 4096@15 FPS. I've upgrade my video card drivers and they work fine with everything else. Processor usage is fine, nothing in the event logs. Regards, Mark McCarron From: mark.mccar

I have been using the WX GUI FFT Sink for a while now and I notice, regardless of the power of the machine, setting an FFT above 4096 causes it to effectively grind to a halt and UI become grey. Is this a python thing? Or is there a way to accelerate this block??? Regards, Mark McCarron
