I've tested Prospector with a rig which has RX 570's 4GB. Was getting nearly 15Mh/s - although not sure how many GPU's were actually functioning?? With SG Miner am getting about 16 Mh/s each card.
But unable to see which cards are working and how may Mh/s for each card, so would like to see a persistent table showing outputs as in SG Miner. How do we optimise it and tweak intensity? Also how do I turn / flag off the CPU miner? Can you pls add some more detail on how to better structure the config.json file...
