Widescreen FOV fix

SULFUR Widescreen FOV Fix

A small BepInEx plugin that fixes SULFUR's incorrect FOV behavior on ultrawide and other non-16:9 displays.

SULFUR's native widescreen implementation uses an incorrect FOV calculation, resulting in a vertically compressed/Vert- style view on ultrawide resolutions. This plugin forces the Unity camera to use a proper vertical FOV while also correcting the camera's aspect ratio.

Tested on 3840×1080 (32:9).

Features

• []Fixes SULFUR's widescreen/ultrawide FOV.[/]

  []Uses Unity's actual vertical camera FOV.[/]

  []Correctly applies the physical display aspect ratio.[/]

  []Configurable vertical FOV.[/]

  []Works through BepInEx.[/]

  []Does not modify the game's files directly.[/]

Configuration

After launching the game once with the plugin installed, BepInEx creates:

SULFUR\BepInEx\config\com.horplus.sulfur.cfgFor example:

C:\pathtogame\SULFUR\BepInEx\config\com.horplus.sulfur.cfgThe desired vertical FOV can be changed in the configuration file:

VerticalFOV = 90The default is 90° vertical FOV.

Other available settings include:

• []EnableFix— Enable or disable the plugin.[/]

  []ForceAspect— Force the camera to use the actual screen aspect ratio.[/]

  []ForceFOV— Enable or disable the FOV override.[/]

  []VerticalFOV— Desired vertical FOV in degrees.[/]

  []LogValues— Enable diagnostic camera logging.[/]

Installation

• []Install BepInEx 5 for SULFUR.[/]

  []Extract the contents (just the DLL) of this mod into C:\pathtogame\SULFUR\BepInEx\plugins[/]

  []Launch the game once.[/]

  BepInEx\config\com.horplus.sulfur.cfgif you want to change the FOV.[/]

Recommended FOV

The default is:

VerticalFOV = 90On a 3840×1080 (32:9) display, 90° vertical FOV corresponds to approximately 148. 3° horizontal FOV.

You can lower the value if 90° is too wide for your preference.

Compatibility

This breaks scopes because it continually reinforces the FOV, but for me this is a worthy sacrifice. Scopes still work but they no longer zoom

Why does this exist?

SULFUR's built-in widescreen support does not properly preserve the intended vertical FOV when moving away from 16:9 resolutions. On ultrawide displays this can result in a significantly narrower vertical view than expected.

This plugin bypasses the game's incorrect FOV assignment and forces the camera to use a consistent vertical FOV instead.
