Mining x11 (Logic Coin) for the first time with ccminer-v1.0 and here are my results:
ccminer30
660Ti SC --> 1750 khash/s
660Ti ------> 1670 khash/s
780Ti SC --> 3040 khash/s
ccminer35
780Ti SC --> 2700 khash/s
So the big iron runs compute 3.0 better than 3.5.
I am also seeing a higher hashrate with compute 3.0 compared to 3.5 on a 780Ti (mining x11 at drkpool):
ccminer30 - ~3500 khash/s
ccminer35 - ~2900 khash/s
Odd.
