I released dual miner for AMD three months ago, still noone created similar public miner for Nvidia (though may be there are private miners, I don't know). I did not expect it.
I have an agreement not to create Nvidia miners, but it is about to expire.
So you will see dual miner for Nvidia soon anyway.
I'm working on it and it takes a lot of time. Right now the miner already supports Nvidia for ETH mining but I doubt that anyone is interested in it since it cannot offer better speed, so I don't release it for now.
Dual mode is still under development, a different approach is required (compared to AMD), hope to finish it in 1-2 weeks, it's a lot of work and tests on different hardware.
Thank you write Dual miner program.
It works on my AMD 7990,380,390 well.
I have nvida 1080 * 1,1070 * 2,980ti * 1, there are now nvida graphics program to test it? I am not a professional miner, it is like tossing hardware and software, huh, huh.
