voice responses on PC and Mac/with Parrallel

I will be using the PC version of superlab 4.00 but I will be running it on a MAC powerbook laptop in Parallel. I would like to know if a voice response can be measured to 1 msec accuracy buy plugging in a mac microphone. I know that a mac mic will give you 1 msec accuracy on a mac superlab MAC. I also know that a voice key is needed for a PC. But what about the situation above?

For your situation an SV-1 is needed for the microphone setting. We have never tested the timing running in a virtual environment, unfortunately we do not know the exact timing. I have discussed this with one of our developers, he states the timing is better then using a built in microphone and that the accuracy is under 20 ms.
