Another small Update: I switched the game from Direct X11 to Vulcan, and while not perfect, its way more in line with what I'd expect the game to run like at this stage of development. I'm seeing 30fps across the board, with rare momentary dips to 25, including in areas like the blighted village and goblin camp, which ran hideously on my machine when I used Direct X11. Settings I was using were the same as the initial post except a few settings:

Instance distance: from low to medium
Texture Filtering: from Anisotropic x4 to x16

I'll be using Vulcan going forward up until something goes really wrong with it, and it forces me back to using DX11.
