Frequently Asked Questions
What is the difference between horizontal FOV and vertical FOV?
Horizontal FOV measures the width of your field of view in degrees, while vertical FOV measures the height. Many games (like R6 Siege or Battlefield) use vertical FOV in their settings menu.
What FOV is 90 in CS2 on a 16:9 monitor?
CS2 and Source engine games base their 90 FOV setting on a 4:3 aspect ratio. On a standard 16:9 widescreen monitor, this expands horizontally to approximately 106.26 degrees.
