v12.1:
- slightly improved speed for some cards, about 410H/s on stock 390X, 450H/s on stock Nano, 290H/s on stock 280X, 300H/s on stock RX480.
- slightly improved stability. If it is still unstable for you, reduce "-i" value.
- fixed issue with wrong hashrate when "-li" or "-ttli" options enabled.
Also (before the crying starts again): on two of the test rigs (Polaris 470 and Hawaii 290x) I had to reduce intensity -i by one more notch to reach full speed. But it's still faster than v12.0. 390 Hawaii don't care much about intensity, could not yet see any difference between -i 7 and -i 8. Nice!
