Could someone plz tell me what - C does... I looked in the readme file and its not there. Thx.
CPU MINING--
The "-C" command line flag enables the "CPU Mining" boost in sp_ 's branch of ccminer. It makes a big difference in hash rate for some algos, as the cpu is assisting the gpu in processing the data. I remember chatting at you about it before. As far as I know, sp_ 's branch is the only one that uses this fllag.
It increased my Quark hash rate about 500kh/s to 11.5MH/s with my GTX 960. --scryptr
That's with an unoptimized CPU miner. If you want to co-mine with the CPU you could try cpuminer-opt.
It does quark at 1.2 MH/s on a i7-6700K. But I prefer to mine more CPU friendly algos.
