Hey Claymore,
Why are you hesitant to make the miner work with AMD 14.6 driver? Seems like most miners out there gain a performance of some sort from it.
I test 14.6 for every version and check its performance in details. It is not faster than 13.12. I can release two versions for 13.12 and for 14.6, but actually it's very easy to make miner use 13.12 even if you have installed 14.6:
