Okay then, my apologies to anyone I may wake up by posting.  That's cute, there's a warning about waking stale topics.

My windows 10 just upgraded to 1803 and my compacs have dropped in hashrate.  Anyone have a similar experience?

Yes, compacs, not 2pac.

Yes, 1803, not 1809 (I like to delay as much as possible).

With the upgrade to 1803, I had to reinstall zadig, which had been upgraded since I originally installed it.  After noticing the decrease in hashrate (5.5% on each unit) I dug out and applied my older version of zadig, but to no avail.

The version of cgminer as well as the batch file used to lauch it have not changed.  Next stop will be the multimeter if nobody else has noticed the drop.

What?  I like these little guys.
