Good day. Want to share my results.
Performance of my hardware with 10.2 (tweaked hashes and -dmem 1):

   R9 290x (1122/1376)  928 H/s  ( -h 968 )
   R9 290 (1124/1376) 931 H/s ( -h 960 )
   RX 580 nitro+ 1340/2000 1020 H/s ( -h 1896 )

And 11.0 (auto hashes and -dmem 1)

   R9 290x (1122/1376) - 910 H/s
   R9 290 (1124/1376) - 893 H/s
   RX 580 nitro+ (1340/2000) - 1036 H/s

By changing hash parameter for GPUs I managed to up 290x hashrate almost to old value, but 290 won't go more than 893. So for me old version is better.

Thanks for sharing, what are your voltage settings ?
