Hi guys - it's not clear to me from the last umpteen pages of the thread, so I will pose the question:
Does upgrading from 14.4 to 14.6 increase the hashrate for x13 mining?
I can clearly see big gains being posted by lots of people for x11, but it's not clear if 14.6 is giving a big advantage for x13. I have 14.4 drivers right now, using lasybear's miner, and am getting 2.54Mh/s on my 280x's with x13 mining at intensity 16.
Is it worth it to upgrade to 14.6?
No, no noticeable change with my 280x's over 14.4 with x13. But why not try the trick where you put the open dll files of the 14.6 in the sgminer folder?
