Plotzie I do the exact same thing as you and have no problems but I have a much more powerful PC. I assume you are using BIAB in plugin mode so maybe you can close the program once you transfer the tracks into Reaper. I also try to make sure all my tracks in both Reaper and BIAB are at 44.1 kHz sample rate to reduce load on the cpu. I already posted a reply to you on the Reaper forum.
