I have two different 750tis running WW. I have one at home on win 7 that runs WW wus in about 9000 seconds (minimal cpu usage). I have one at my parent's, win 10, (staying here watching pets) that takes about 12,000 seconds (minimal cpu usage). I thought it might be a driver thing so I updated the driver on this one. i haven't seen one run through yet but before and after the driver update it was using about 75% of the gpu. I can't confirm the other one at home's usage but I'm confident it's near fully loaded, and that's why it beats it by about 25%

I see in the past that some win 7 machines were running slower but this is the opposite for me.
I reduced CPU tasks to see if it was a bottleneck and that doesn't seem to effect run times. Should I try to track down the driver the other is using?
