The 68 fov in cs is irrelevant. You can't change the fov in cs unless you change your resolution. For example, you're playing on 4:3 stretched, so your actual field of view is 90hdeg, which makes the vertical 73.74. If you played on a 16:9 res, your horizontal field of view will become 106.26, but your vertical will still be 73.74. What monitor distance are you using? Horizontal or Vertical?
