considering, I never worked on quark, your comparison is irrelevant as usual
Your Lyra2v2 kernal is slow on the gtx 950 and the gtx 960. I have improved it. It is faster on all the maxwell models. My modded kernals are 100-200KHASH bether on the 750tis'
Around 5%.
It's enough to prove that my work is faster.
you just tweaked kernel parameters (which were adjustable by the user in my version btw), so no there is no real difference...
(except the huge overclock on your cards)
No. I have done more. My kernel compiles down to 110 registers and no spillbytes. Yours is 213 regs. Do a filecompare and check for yourself.
