Field of View(FOV), in my opinion, is the most important console command CoD4 has to offer. The difference between getting a kill or getting a death for me comes down to my FOV sometimes. For those who are unaware of what FOV is, I'll explain.
FOV is the distance, in width, that you can see while playing. Increasing this width allows you to see more, thus maybe catching a player on your screen you wouldn't see otherwise.
The console command for FOV is:
/cg_fov ## Before you try this command, here's how it works.
FOV is based on increments of five ranging from 65 to 80. The stock FOV is 65. The highest is 80.
For example, I could set my FOV to 70, 75 or 80. I recommend 80 because you will see more. So if I wanted to change my FOV from the stock 65 to 80, I would open console and type:
/cg_fov 80 It may seem weird at first, but try your best to get used to it because FOV helps your gameplay A LOT.
Here's a screenshot of the difference between 65 and 80. You can see the red circles I added showing where I can see by using 80. With 65 I couldn't see those spots.
