I am now running a Radeon Pro DUO (Fiji) GPU which can run Radeon Pro Software for Enterprise 19.Q4 Driver.
I request that AMD add support for Commercial Desktop GPU such as R9 Nano, Fury, Fury X (Fiji) based GPU in Radeon Pro Software for Enterprise 20.Q1. I have many of those GPU. Finding more Pro DUO cards is difficult.
Usual conditions would apply - similar to those for Polaris and Vega based Desktop GPUs.
It works but you do not guarantee professional quality if running on commercial desktop GPUs.
If you coulds also enable other 300 series GPU like R9 390X that would be a bonus, although I realise they are different GPU Architechure - Hawaii XT versus Fiji Pro/Fiji XT.
