Starfield FOV and Optimization Mods Are Already Out on Nexus

wccftech.com:

As most PC gamers will have noticed right away when launching the game, there is no Starfield FOV (Field of View) slider in the game's settings. This is unfortunate since the default setting appears to be 75, which is lower than preferable, especially for those who experience motion sickness when playing in first-person view.

Thankfully, several mods are already starting to appear on Nexus, including some that allow players to increase the Starfield FOV value. User Hellstorm102 provided a downloadable StarfieldCustom.ini file that needs to be placed in the Documents/MyGames/Starfield folder to enable the increased Field of View. The provided file sets FOV to 100 for both first-person and third-person view, though any user can modify the .ini with different values as desired.

Likely, Bethesda will eventually add an in-game Starfield FOV slider at some point, but mods will have to do in the meantime.

While fixing the Starfield FOV was one of the community's main priorities, there are plenty more mods. For example, an optimization mod already tweaks the values of shadow distance, reflection size, and more. It was created by Erokk, one of the makers of the Cyberpunk 2077 Path Tracing optimization mod. The author clarified this is unlikely to make a big difference in terms of frame rate due to the relatively minor tweaks made. However, Erokk also said is just the beginning, hinting that more ways to further optimize Starfield are being looked at by modders. If you do install the modded .ini, make sure to switch between presets to activate the modifications.
