v11.2:
- some improvements in AMD GPU kernels, it can increase hashrate a bit in some cases.
- reduced some delays, it will cause a bit less stale shares.
I had to re-tune with v11.2 but afterward, I'm seeing a 1.2% increase in hash (580/8GB cards) ... nicely done. It's like getting the dev fee back.

That's ETH + Blake2s. I would imagine ETH only would require a re-tune via -dcri as well to find the sweet spot.
