No rigs, ccminer is reporting 250MHs using just one nvidia 1050ti card lol Cheesy Using linux, compiled from source. Moved the nvidia on another coin now, I wont bother with this weirdness...

A GTX 1070 does 1.3 Mh/s so there's an issue with your miner. Or maybe your card crashed.

Really? That's the first I've heard of decent GPU performance, but it's still less that 2x my 6700K.

750 Ti: ~0.2 Mh/s
970: ~0.8 Mh/s
1070: 1.3 Mh/s

But all of them are at less than 40% power so there's massive improvements to be gained.

I doubt that. The cuda lyra2 is already highly optimized. The cores are probably stalled waiting on memory.
Some optimization of memory  throughput may be possible, I just did some in cpuminer but once the memory
bus is full no amount of compute optimization is going to help.

The problem with these algos is each thread requires its own buffer. On a CPU with 8 threads that's no big deal
but on a GPU with hundreds or thousands of threads, well you get the picture. I don't know if the GPU miners
can share a single buffer among a group of threads. That may allow more threads to run.
