The game limits FOV between 70° and 80°.
This tool lets you set the FOV anywhere between 1° and 160°.
To use the tool, make sure you've run the game at least once, then close it. Run the tool, and choose which player profile to update the FOV for.
Then enter the desired FOV and press enter. I recommend either 100 or 110.
If all goes well, press any key to close the tool, then launch the game. Enjoy.
If you go into the settings, the FOV slider will be out of bounds. You can safely adjust any other setting without affecting the FOV. If you touch the FOV slider, you'll revert the FOV changed by the tool. To fix, close the game and re-run the tool.
