take out the whole cpu priority crap.. and im using palginmod 1.1, your using 1.0 but should still work. I get 26 MH/s on gtx1070 not OC'd running this and works with no prob
I just tried yours on my system with this config and it worked with no issues. copy and paste
ccminer -q -a skunk -o stratum+tcp://mining-enthusiasts.net:3033 -u Ryosaki.GTX1080TI -p x
doing it this way without setting -i set my automatically at 21 intensity. you can add it at the end with whatever intenisty you want, experiment with diff settings
here is link for palginmod 1.1
