We want to pay a fee. Just not 2.5%. We want to pay 1% fee.
As always, I will reduce my fee when a miner with similar speed is available. Though I'm not sure that you will really notice 1.5% gain which you want.
We were there up to your version 2.0, but it's kind of hard to keep up with you. :-)
My most recent ideas in theory should get as high as 150sol/s on a Rx 480.
I don't like Linux, so I used Genoil's miner to see the speed. May be it shows same speed on Polaris, but I tested it on 390X card. Two Genoil's miner instances showed me about 30H/s, my first version shows about 50H/s. You can check it easily. May be on Linux or on different GPU situation is different, I did not check it, but >90% people saw that my v1.0 is much faster than SA engine. Though 10% saw that speeds are similar or SA is better, they all use Linux, so may be it's the reason.
So I reached 100H/s on my favorite 390 cards but it can show even more speed.
I think there is more of a difference between drivers on Linux. Maybe speed difference also people with different CPUs? Some have posted their personal optimizations, but it is hard to judge typical speeds for sure.
