I've tested this on all my rigs and at first glance all seemed great.

I did have to bypass windows not allowing me to assign a unsigned software.

My hash rates appeared to be the same as before the nasty Dag creation started.
My power usage is the same after under volting.
My REPORTED hash rate to the pool of course matching my Rigs hash rate.

BUT here's the kicker my effective hash rate on the pool is about the same if not a little less than it was before applying the driver.  So my question is this.
Is the driver merely creating false readings on the cards with no actual effect on total shares submitted to the pool much like when you think you have found the golden card that reports a hash rate of 45Mh/s when in reality its only hashing at the same speed as the others.  Had the new Driver running for 7 hours now ....so of course I need test some more just incase its the pool on a go slow....although it normally only takes a couple of hours to get fairly accurate readings.
