Thanks for testing. Just updated to beta5E+ release. x22i about 10% faster.
I tested the beta5e++ version and I have as 20% faster now on the x22i algorithm and it produces as much as 2.8 Mhs on my RX 470.
Excellent work! Soon it will be the fastest in the algorithm x22i
P.S. I had to remove the option -g 2, with which the miner did not start on my video cards with an "Error -4: Enqueueing kernel search15 onto command queue".
