First, Go to


Options>


Keyboard/Mouse>


Allow Developer Console and Enable.


You can access the console by clicking " ` " At the top left of your keyboard below the Esc button.

Now, Go to your game. Hit ESC, then type the following into the console.

cl_fov 100


viewmodel_offset_y 8


You will see the difference when you have configure both the FOV and the View Model, For example here:


cl_fov 90 (Default)


cl_fov 100

Now, Same as the FOV, we can type in a certain command to make a view model more wider and not too big for the screen.

Use this command:


viewmodel_offset_y 8


Example


viewmodel_offset_y 4 (Default)


viewmodel_offset_y 8

I hope that this guide helped you! Goodluck and Thank you for taking the time reading this guide! Let me know if it works.

PS: It is up to you to if you want to go higher than 100 FOV or a higher View model. But trust me, Don't go over 120. It can be a little bit dizzy and nauseous to play with a high FOV. Have a nice day!

EDIT: To keep your FOV throughout the game without redoing it all over again, try this method given by @CONNOR (RX800) from the comments. Enjoy! :)

1) add txt in folder where you can find
steamapps\common\Portal 2\portal2\cfg
2) change that new txt to autoexec.cfg
3) write you want (fov and viewmodel) and save
4) in library, where to find port 2, right click, touch properties and write "-exec autoexec" in "launch parameters"
5) and done you can play any level with automatic command
