If you are willing to follow the direction on PC Gaming Wiki on Ultrawide and Outer Worlds, you can get ultrawide resolutions by using a basic hex editor and updating the .exe (after making a backup of the .exe of course). It took me about 5 minutes to do. FOV can be taken to 100-120 in the game settings, and works pretty well.
