My only experience is changing from Catalyst drivers to the Blockchain drivers, then going to the Adrenaline drivers. Adrenaline drivers have 2 different workload modes, Graphics and Compute. Running on the Adrenaline Graphics mode gives me a similar hashrate to the old Catalyst drivers, and running Adrenaline Compute mode gives me similar hashrate to the Blockchain drivers.
I do not maximize my setup for hashing though, so on dedicated rigs, there still might be an incentive to run the blockchain drivers. I turn off my mining program, switch drivers to Graphics, and then play games and when I'm done I switch the drivers back to Compute and turn my miner back on.
MSI Afterburner worked for me with the Adrenaline drivers.
I run a single RX 480 GPU, mining Eth I get ~25 on the Compute, and ~15 on Graphics.
