For whatever reason, this is the only game I've come across where I consistently get much better performance using WineD3D instead of DXVK. Despite what my GPU settings say, this machine has an RTX 2060 Mobile which is only utilized when using PRIME. When launching this game using DXVK, I would get unplayable framerates regardless of resolution and graphical settings - for example, at 1280x720 Low, the framerate would range from about 5-15 FPS. Once I switched from using DXVK to WineD3D, I was able to play at my monitor's maximum resolution of 1920x1080 on Ultra (minus realtime shadows) at much more playable framerates (anywhere from 30-60 FPS depending on where in the house I was, with dips down into the 20s outside when looking at the fire pit for whatever reason). I have a feeling this is just down to some weirdness with my specific computer, but if you're having issues running this game at a playable framerate then try switching to WineD3D.
