True, i couldn't get it work with xintensity at all. Using --rawintensity 512 -w 4 -g 1 its working but its slower A LOT than claymore xmr.
Sorry, the settings above were for daggerhashimoto ... try using
-g 2 for CryptoNight:
--rawintensity 512 -w 4 -g 2
It should yield you basically the same speed as with Claymore CryptoNight Miner.
