No, it's not choppy on the RECEIVING end at all. It's only laggy on the n900 if one chooses to use 640x480. But then again I don't really have my DSP overclocked too high, and one running with a higher clocked dsp as well as perhaps 1,150Mhz (which I used to run at permanently before the entire idea came up to stream to PC through n900's camera) might not see a lag. I'm on 1,000Mhz and 500 dsp now.

But like I said with 320x240 no lag is noticable on either ends.
With that said, happy streaming wirelessly.
