CurseForge and Overwolf are joining forces!
This client-side mod stops Minecraft from changing the Field of View when running, using potions and bows, etc.
Since 1.16.2, Minecraft now has this feature built in! You can find the FOV Effects slider in Accessibility Settings - just change it to Off to replicate what this mod does.
Mod Menu can be used to toggle this setting in game.
