The DirectX 12 benchmark results from Ashes of the Singularity caused quite a ruckus as this early DX12 test showed AMD performing really good versus NVIDIA but now we get a new piece of the puzzle with the release of an early DirectX 12 benchmark of Fable Legends from Lionhead. This game is coming out later this year so final performance is likely to be better due to further game and driver optimizations. Unfortunately, there's no DirectX 11 version of the benchmark so we don't know the performance benefits of DX12 in this game.
You can check out a review at The Tech Report and AnandTech. This test shows NVIDIA in better light but also reveals AMD's Fury cards to be only marginally faster than the Hawaii-based siblings. Here's what The Tech Report says:
The GeForce cards perform well generally, in spite of this game's apparent use of asynchronous compute shaders. Cards based on AMD's Hawaii chips look relatively strong here, too, and they kind of embarrass the Fiji-based R9 Fury offerings by getting a little too close for comfort, even in 4K. One would hope for a stronger showing from the Fury and Fury X in this case.
