Hashrate/Efficiency Improvement on some gpus
Added new tuning parameter --nr
This is a per gpu option and is related to the number of rounds done in one iteration.
Default is 1 and the values are 1,2,4 and 8. The best value for almost all gpus is either 1 or 2.
Make sure you try both --nr 1 and --nr 2 and let the miner find the best --nt value to get a baseline.
Note that higher --nr values might lead to more power fluctuations and higher stale shares.
