There are two variables governing the camera distance, cameraDistanceMax and cameraDistanceMaxFactor. You multiply the value of these two variables together to get the maximum camera distance.

Before Wrath, ..Max was 15 and ..MaxFactor could be set to 3.33333, making the total about 50 yards.

Now, ..Max can be set to 30 and ..MaxFactor can be set to 3, making the total about 90 yards.

The camera distance slider in Video options adjusts the MaxFactor variable, but only for values between 1 and 2

/console CameraDistanceMaxFactor 3
/script SetCVar("cameraDistanceMax",30)

Change sliderin video option to some low value, and then to max.
