I just grabbed 1.9, and am attempting to benchmark now, but it seems it's only using one of the 2 1606 3GB in this rig in the benches. Is this normal/expected behavior?
Edit: I also switched off hide miners in the setup, yet it is doing so, I'd much rather be able to see their output rather than having to read logs to help troubleshoot as I go.
I think perhaps it benchmarks one card at a time? So you have to wait on the first before the second starts? I ran into the same thing and ended up just benchmarking them separately using the check boxes.
