I tried using dxvk with dx11 and the game started to stutter A LOT in Lion`s Arch. The FPS was good while stading still but would crank when I started walking, maybe that is not true in WvW as I did not go there to test it.
I currently have a 5700XT Ryzen 7 3800x and 32GB 3200MHZ running the game with an m2 ssd. Pure DX11 however, there was no stutter whatsoever, but got lower framerates.
