As far as I can tell the only APU's that support DX12 anyway are the 7000 series. It would have to be a Kaveri or Godavari apu to support DX12. Your chip is richland and you would need to upgrade if you wanted DX12 support. Although those chips have DX12 support it also doesn't mean they have full support. DX12 has different tiers of support as well now.
