So after I saw this message, I successfully generated a deposit address on Cryptopia and made a deposit (been now 23 hours since), but the deposit is still not visible despite having 871 confirmations:

How long until this is fixed?

How come I only get 80% power with my GTX 1070 instead of 115%, unless the "Power & sleep settings" (as typed in Windows search) window is opened (can be minimized) ?

Is this a bug with the miner or Windows 10 ?

I've got Windows 10 with Anniversary update installed, haven't installed Creator's update yet.
Edit: Got Creator's update now with the latest insider build (fast ring), still the same problem.

Found a fix: Change Nvidia Power management mode from "Optimal Power" to "Prefer maximum performance" or "Adaptive".
