Some of the “Ultra” graphic settings are a bit conservative. For instance the VRAM limit (r.Streaming.PoolSize) for texture is only 1.5GB, and the view distance doesn’t go beyond 1.0.
The low VRAM limit can easily cause the game switching to lower resolution textures when your house has a lot of clutter items from mods. And modern GPUs can easily handle a view distance of 1.6, which looks a lot better for stuff like grass.
While I appreciate the game needs settings for people with low end GPUs, that is just not what “Ultra” should target.
