Yes, sure I get this hashrate by using miner by tpruvot. Big thanks  to tpruvot !
Have a try - it might get you to 20+MH/s

My .bat file:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ccminer -a skunk -o stratum+tcp://sigt.suprnova.cc:7106 -u username.miner -p password --cpu-priority=3 -i 21
pause

Tried higher intensity, but so far 21 is best for using PC while mining.

I use default clock settings for 20MH/s-20.5MH/s and only lower power to 90% (Zotac firestorm app)
And my card is 1060 zotac amp+ 6G

I tried overclocking to +150 core and +250 memory it was staying around 21.5MH/s - 22MH/s with power at 90%, but normally I go for default values and setting power to 90% (power 100% or 90% hashrate difference only 0.01 - 0.05 MH/s).

Tried multiple miners, but this one gives me most stable hashrate without any overclocking

Hope this helps
