This was inspired by a mod called Dynamic Elytra FOV. I have tried it and unfortunately they are incompattable so you can't use both at the same time :( unless you turn off dynamic elytra fov from the in game settings with mod menu.

There is a config file for this mod but I am new to mod making so it doesn't work with mod menu. You'll have to go into the .minecraft/Configs folder. Restart the game to see effects.

If you are a Quake Pro player then I would recomend turning down your FOV because it does get quite zoomed out. Try it and see if you like it but if it's too zoomed out you can either go into the config file and turn down the Effect Strength or lower your FOV.
