I did an extensive review of your mod, and within 3 reasons stated below will prove that your mod is unfortunately an Illusion.
Theory 1
Your mod (Fov=100) only gives a bigger view of what you are playing. This in the running will give a sphere effect to the game.
The game was not made for these settings and it's why it looks very weird.
As you all know Fov means Feild of View, and if you wan't to get more detailed you
can clearly see how the default Fov=55, maintains the aspect ration of the screen,
and when Fov=100 the screen will looked warped.
Below has two pictures (Created by me)
Y.P.O.V. = Your Point of View
Theory 2
Not only that but I did timetrials.

Two list below 1st= With Mod (Fov=100), 2nd = Without Mod (Fov=55).
I used my Ipod to time the seconds from one distance to another on the same map, with the same class, with the same server. The stats are pretty straight foward.
To remind you the times are ordered in seconds/mileseconds. There is no difference between mod and default settings, my conclusion is that this mod is an illusion.
First (Fov=100)
- 5.98
- 6.08
- 6.09
- 6.08
- 6.08
Second (Fov=55)
- 6.08
- 6.09
- 6.01
- 6.10
- 6.08
Theory 3
When playing the game I noticed that I couldn't overtake my fellow players, which means I was running at the same speed as they were.
Good find though!
