For me to switch Id need, and I suppose as many others:
most importantly, flawless DAG verifications as in other miners with no need for extra parameters etc. this is where it took me days to get it working with no luck
tuning , cclock, mclock etc.
dual mining - alph, ton
The latest version have a function to copy a working dag over to the other gpus, so all you need to do is to downclock one of the cards in the rig, or use an older card together with the 3070 in the rig.
