Subject: Getting full performance out of multiple GPU's

I've got an 8-gpu cracking rig that I've inherited from someone who had it
setup with hashcat. Apparently it worked well there.

As I prefer john, I've been trying to get it set up. I have it up and
running, but the Utilization output from --list=opencl-devices hovers
around 0-1%. Is there a way to improve this?

I'm running John the Ripper 1.8.0.12-jumbo-1-bleeding-6144b8f (freshly
re-pulled and re-built today).

Thanks,
Adam
