Using Adrenalin 17.12. Have mix of 7 brands of RX 480's and mix of modded and unmodded VBIOS. Works fine in Win 1709. After upgrade to Win 1803, system is extremely slow. Mouse pointer hangs for several seconds every 10 seconds, Radeon settings painfully slow (takes several minutes to open the GPU settings page). Can't mine! Tried Adrenalin 18.05, no solution. I'm reverting to 1709.
Anyone else with experience using Win 10 1803 (April 2018)?
