Anyone got a different miner or GPU miner working yet?
GPU mining is not likely to be worth the effort/power costs, if this algo limits GPU performance as much as yescrypt does it will be about 3-5X slower than CPU mining. Surprisingly the best miner for me is the wallet's setgenerate command, the cpuminer-opt is about 20% slower for me. I'm sure someone with better skills than me can create an even more optimized CPU miner eventually.
Are you saying wallet's setgenerate command is faster than cpuminer-opt?
This is impossible, what operating system are you using?
It's not impossible, it's the truth. On Windows 7, Windows 10, and Ubuntu mining with the wallet is considerably faster than using the other miners. I've tested this on an i3, i5, and Ryzen 7 processor and it's about 20% faster in each case. It seems that there is a lot of optimization that needs to be done in third party miners to compete with the dev's algo.
What's more likely is you are not setting your threads optimally. You have to try different thread amounts to find the best one. The wallet probably automatically selects the best number of threads to use.
