>>314870853they don't. they struggle with AC and it's not a part of mandatory spec, hell Unity, UE4 and CryEngine didn't have support for it at the time, still don't have it as far as I know.
Fable Legends doesn't use AC and nVidia is fine with it. They hate AC, not DX12. Because they cards suck at it.
Also new nvidia driver improves AotS performance.
