Re: WinMiner v1.119a - auto switch windows app for multi miner optimization
XRM-Stack is not very good. Atm I use Cast XMR any my RX570 has a Hashrate between 810-880 H/s and my Vega 56 has 1920-1960 H/s. On Stack all Cards have unter 800 H/s. Maybe you can put Cast XRM into winminer for Monero mining.
Cast XMR is already part of WinMiner 
If you have any issues with XMR Stak you can easily disable it in the miners tab.
We are waiting for Cast XMR to add Cryptonight Heavy support (for supporting Sumokoin)
Next on WinMiner's list for this family - XMrig , stay tuned
