I just found out CL_DEVICE_TOPOLOGY_AMD does not work with the latest AMD drivers.
This explains why GGS cannot detect GPU's properly with these drivers. Grrrrr...
Edit: I just checked Claymore's Dual Miner and he doesn't even attempt to fix this problem like he used to. lol
I guess I could issue a warning and be done with it...
Yes. You're right. Claymore dosn't fix it in his Claymore Cryptonight miner 11.0 even, wich he is released latest... He wrote that it's AMD issue and he wrote to AMD devs to fix it...
