On 5850 and 6970 there is improvement with 14.6 opencl files
5850 now makes 900+KH on x13, 6970 is above 1400.
I used the version from
https://bitcointalk.org/index.php?topic=658975.0, initially I reported no speed up, but I had messed bat/conf files.
Tested under 13.12 with opencl files from 14.6 copied into sgminer folder and deleting all bins
I found the opencl files in AMD folder inside \Packages\Drivers\Display\WB6A_INF\B171094 (after decompressing the 14.6 driver package without installing it, or with 7zip)
I don't know which are needed, so I copied everything that had "opencl" or "amdocl" in the filename into the sgminer folder (8 files, dlls & exes).
Deleted all previous bins, and now it's even better (+3%) than using the bins from 14.6 (I have 14.4 drivers installed).
