I'VE NOTICED THAT INTENSITY SETTINGS DON'T WORK--
In the most recent versions of CCminer (2.2+), intensity settings appear to be ignored, and a default setting is applied. Other users have posted about not being able to disable auto-tuning on algos like Scrypt pr CryptoNight.
Frankly, default or auto-tune settings are often the best, but I have noticed that some older tuning parameters are ignored. --scryptr
I have only been wrestling with ccminer for the last 4 hours, and can tell you for certain, every combination of INTENSITY parameter I threw at it, was ignored. The default settings are NOT the fastest for my cards. I have also been spending this whole time trying to learn this crazy "launch-config" parameter, digging through documents to find which of the 1,000 different technical specifications ccminer needs for me to accept. It's parameter list is confusing to say the least.
