Tried setting affinity to use only one processor (I have a quad-core processor and tried using 2 different ones) and unfortunately I have the same results. I read that using "ALchemy" seemed to work...I do have this installed but cannot figure out how to force the emu to use these settings. Does anyone have any input on this? I may try to disable my SB Audigy sound card and see if I can find Win7 64-bit drivers for my onboard sound card if the problem goes away...
