Thanks for the link Matt, nice little tool! I downloaded it and it showed conflicts, and after disabling a few devices it turned out to be my network card. I got the latest driver for it and now it shows green, saying that "This machine should be able to handle real-time streaming of audio and/or video data without drop-outs." Unfortunately the BIAB issue still persists as far as playback when fast generation is turned on.

Peter, thanks for your reply. It's an older PC, 1.4 Pentium, just under 1GB of RAM (768MB). When I look at task manager, bbw.exe has 98% of the CPU while the problem is occuring. Nothing else is running. Are there minimum system requirements listed anywhere? Have CPU or memory requirements increased with BIAB 2010?

Thanks again,

Paul
