I got a second hand RX480 8G video card yesterday and have correct driver installed (drv: Adrenalin 19.20, sys: Win10 x64), but I can't find the setting of GPU workload on "gamming"-----"global setting". It means I could not make this card in compute mode. When I replace the RX480 with my RX470 card, the GPU workload setting come out. So it must be a prevention on hardware or BIOS on RX480.
Is there any body know why and how to fix it? Thanks!
