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.

I CO-MINE WITH CPUMINER-OPT--

I run 6 threads.  BUT, the "-C" flag allows the cpu to assuust/boost the performance of the gpu hash rate.  If you want a better explanation, you will have to ask sp_ .  In simple English, ccminer gets a better hash rate with the "-C" flag set at launch.  Results depend on the algo and hardware.  I use the flag in all of my launch lines.  And, I am usually runnning CPUminer-Opt at the same time, with only a small reduction in hash rate for both miners.     --scryptr
