I am using Phoenix Miner ver. 5.5c to mine ETH using systems with Nvidia and AMD GPU's.  The example bat file shown on PhoenixMiner's site work okay.  However, there are several commands in the bat file that are not described in the "PhoenixMiner Command Line Options (Extra Launch Parameters)".  Examples are "-epsw" or "-mode 1" or "-Rmode 1".  I have searched for an explanation of these commands and have come up empty!  Is there a site somewhere that explains the missing stuff in the example bat file?  Also, what does the "-ACM" command do for AMD GPU's?  I do not have this in the bat file for the system with the AMD RM 5600 XT's and all seems to work.  Am I missing something?  Help appreciated.
