how to set intensity and worksize
hey, i've been using the xmr-stak-amd for macOS, and wanted to thank you for making this! had a question about setting intensity and worksize, is there an optimal setting for my machine? i have a late 2015 imac (radeon r9 m390 2gb). i've experimented with different combinations and found that intensity = 512 and worksize = 8 seems to be giving me the best results (probably around 350-400 H/S) but i was wondering if there was a way other than letting it run and evaluating hash rate to optimize it.
also i do run into the problem that my computer is virtually unusable during hashing, is that to be expected?
