{ "id" : 1, "intensity" : 20, "worksize" : 16, "threads" : 2}, <<-- shouldn't have a comma. took this out
}
that worksize and threads shouldn't be that high.. but anyways 1st card is given an auto intensity setting and 2nd is getting 20.. by a 15 workload and 2 threads try 1 thread, or lower to 8 ws
32 is a bunch.
Actually what is card 0 and card 1 doing? #0 should be doing just optimal settings with the 0 switch.. perhaps you want to have 2 threads on it as well?
it's all about testing..
