Let me put it this way: When The Talos Principle came out, it had a very similar frame rate in DirectX 9 vs DX 11. But then we optimized the game, and the drivers were optimized in the meantime, and now D3D11 is 20-30% faster than D3D9! I have a firm belief that this will also happen to Vulkan vs D3D11, over time However, for now you can actually expect lower frame-rate compared to D3D11. C'mon, it's brand new API, give it some time. :)
