Lower hashes on RX 570 on 2.9.3
I'm getting a much lower hashrate on cn-lite compared to version 2.8.6 on my RX570. I used to get around 1100 H/s and now it's 700-800 H/s. My RX460 gets almost as much my RX570 using the same version and is still about the same on hashrates from the older version. Is this supposed to be right?
