ccMiner v0.2 now supports pools with fuguecoin (like dwarfpool) and has a nice boost for Fermi and Maxwell owners.

I tried getting source code from git and compiling cudaminer myself to see how blake works there 
I got it running after some time but I was surprised to get only around 42 MH/s on my GF GTX670M.
cgminer is much faster (250 MH/s) but that is still very low hashrate compared to the AMD cards which are equally powerful.
I just wanted to ask - is blake in some very early stage and will the performance be improved so we get more than using cgminer?

in case you didn't get the memo: nVidia sucks at compute bound hashing algorithms.
Factor 2 slower than AMD or so...
Now about the 42 MH/s vs 250 MH/s... I don't know how you compiled it. Custom builds
break the warranty ;-)

Doesn't cost much, to do the launch and grab a few blocks. Just in case.
What would be the scrypt-n parameters though?I have never been on a N-factor coin launch
(try autotune first, I think for some cards the T kernel is better)

cudaminer.exe --algo=scrypt:2048 -q -m1 -d gtx780 -b32768 -C2 -lt15x32 -i 0 -H 2
you might have to change the config though...

any thought on spartancoin ?

I'm probably going to try out Rotocoin. Launch is in about 3-4 hours.

So the hashrate velocity reach the 20,14 khash/s (that is very near to the banchmark value that was 24 khash/s)
Some ideas about how reduce more?
Try reduce kernel load more. Some ideas about how reduce more?

You won't get anything decent out of that laptop gpu...maybe try yacoin?

So I think that my hasching speed is arount 24 khash/s (is it so low as value to do something concrete?) and, at first stage I have to change it in 12 khash/s
But what exactly have I to do to perform this operation? You say to me that I haveto reduce the -l...ok...but if execute:
cudaminer.exe --help for the -l paramether it say to me:
Code:
-l, --launch-config gives the launch configuration for each kernel
in a comma separated list, one per device.
So it seems to me that it is not related to the hashrate speed...
What am I missing?
Tnx
Later I will try but exactly what means F4x16 and F2x8
What these value means?
I have read the documentation about the Cuda Kernel but seems don't work because after that I execute my CudaMiner application using this statment:
C:\Users\Andrea\Documents\crypt\cudaminer-2014-02-28\x64>cudaminer.exe -o stratum+tcp://stratum.hasher.ca:3373 -O D4rkAng3l.Andrea1:MyPassword -l F2x8
I obtain the following output:

Hi Cristian, how about new release?
tonight then. After the update performance will be approximately like this.
6x 750 Ti= 510 MHash/s = 3 x 780Ti (all not overclocked, on Linux)
previously it would take you 12-15 750Ti's to get this hash
Is the new release going to bump the performance of 780's and 780 Ti's?
I'm currently getting about 180 mh/s on my 780 and 250mh/s on my 780 Ti. Even then I'm not using 100% of my graphics cards. They're hovering around 90% to 95% usage with or without Chrome or flash open.

What is the average speed difference for scrypt mining between the GTX 750 and GTX 750 ti? Guessing 260 to 300 KH/s @ $110 to $155? Does the extra 1GB memory make that much of difference?
may-be on yaccoin Right, so-what's the actual KH/s for a GTX 750? Couldn't find on spreadsheet.
I got about $220 to spend. One GTX 750 ti or two GTX 750's. ;-)
Opinions?
