Radeon VII on Linux - Low Hash Rate

I'm mining XZC, running Ubuntu 18.04.2 with https://github.com/fancyIX/sgminer-phi2-branch and a single Radeon VII. I have only been able to get a hash rate of ~2.2Mh/s and from what I've read online I should be getting ~3.3Mh/s.

./sgminer --kernel mtp_vega --intensity 19 -o stratum+tcp://xzc.2miners.com:8080 -p x -u ...

Is anyone mining with the Radeon VII on Linux with decent results?

Thanks
