The DX12 update on DE:MD has been a disappointment for me.

The internal benchmark of the game says I gained 8% on average FPS (~56), but the whole thing is a stuttery mess on the actual game.

On DX11, on a mix of Ultra/Very High settings, runs very smooth (51 Average) and looks gorgeous.

Even on a R9 390X with 8GB, it only reverts to smooth on DX12 with default High settings. My Average FPS goes up to 65.

And yes, I'm using Crimson 6.9.1.
