The game can support quite a bit more, if you are running it off a SSD and have a half decent GPU, then in game options allow.

First load the game and max everything while turning off Chromatic aberration.

Then quit game and goto
C:\Users\"YourUserName"\AppData\Local\Indiana\Saved\Config\WindowsNoEditor

Open Engine.ini with a text editor and add.

[SystemSettings]
foliage.LODDistanceScale=10
r.ViewDistanceScale=10
r.Shadow.DistanceScale=10
r.StaticMeshLODDistanceScale=0.25
r.SkeletalMeshLODBias=-2
r.MipMapLODBias=-1
r.MaxAnisotropy=16


This will play 100fps min at 4k on a 4090 and should be good at 1080p on pretty much any mid to top end card for the last 3 generations of GPU.
To tweak for best performance at your GPU/Res.
Reduce the following to a min of 5(4 is in game ultra settings)

foliage.LODDistanceScale=10
r.ViewDistanceScale=10
r.Shadow.DistanceScale=10

1080p example included. has horrible compression due to needing to get its size small enough for the forums, but it still looks better then the default game.
