Kev,

6 ms buffer in ASIO could certainly cause stuttering. Try increasing it to a large value (say 100 ms) and see if that helps. If it does, move to lower values from there until you find the limit that works.

Also, the antivirus program could be contributing. I don't know enough about your a/v software to help with this. Do you run BIAB/RB from a USB drive and not the computer's hard drive?
