In our opinion, the most significant improvement has got to be the increase in SPEED. The two issues our clients found most problematic with DMPE were speed (a slight overall lag in time before the spoken words appeared on the screen, making DMPE slower than Dragon Medical 10) and latency issues (unusually long delays before the spoken words appeared on the screen). DMPE 2 appears not only to be faster than DMPE, but even faster than Medical 10, with seemingly no latency.

Tom,
I just upgraded 3 days ago from 11.5 to the DMPE2, and have only used for one day, but I am still getting the lag, and I think it is even longer than with 11.5. It is taking up to 10 seconds before any words show up when I first turn on the Dragon mike (power mic ll) and start speaking, and was wondering if there is an easy fix. My computer is 64 bit 12 ram and windows 7.
