So for anyone that stumbles upon this post: I've found a workaround for Nier:replicant.
Go grab a latest release of this: https://github.com/doitsujin/dxvk/releases
Use 7zip to unzip and untar the archive
Put d3d11x.dll and dxgi.dll in the same folder as game executable
This worked for me on RX 5500M, Windows 10 22h2, games performance went from stable 15 fps to stable 60
