Added another 5% or so on all my rigs with older cards using the -i 2 switch.
On my Rigs with newer cards, such as the RX series, I actually seen a slight decrease versus version 2.0. I have tried all three intensity levels and even the -i 2 gives a bit less sols and the CPU usage is greater than in version 2.0. I am still playing around as it might have been my lowered clocks, but it seems this version was geared more toward the older cards.
Yes I did not have time to improve performance on Polaris yet.
Thanks for the clarification! Great job though on increasing the performance on the older cards. Now I know to focus on tweaking them and not worry about my RX rigs for now, I'll keep them on V2.0.
