Worksize should be 64, don't bother setting TC, GPU threads 2. Basically the same as my earlier screenshot.
It doesn't work. Too much hardware errors. Tested on various cards with all possible combinations of settings. What I notice is that if I leave old 14.9 *.bin file it works but then there is no performance increase at all.
i have the same problem. only HW or above thr target, i use Win7 64x 14.9 Beta
