    14.9 and higher OpenCL performance

    wolf0

      I've tried dozens of tweaks to my Groestl implementation, and it refuses to get anywhere near as fast as pre-14.9 code. The pre-14.9 code is just butchered on 14.9 - a rewrite makes it better, but the performance is still dismal. Are the changes in 14.9+ permanent, meaning I have to not upgrade for the forseeable future?
