Low and high FOV: the visibility and target size tradeoff
A low FOV makes central objects larger. A high FOV includes more surroundings. Neither angle is automatically the better setting for every game or player.
Low and high FOV are relative descriptions, not two fixed camera modes. Here, 75° and 120° create a clear contrast at the same 16:9 aspect ratio. The narrow camera concentrates on the middle of the range. The wide camera includes more side boxes and targets. You can inspect both without moving closer to an object or changing its size.

Look for what enters the frame
Start with both cameras facing forward and compare the outer edges. A box that is outside the low FOV may be clearly visible at the high FOV. This is extra angular coverage, not extra detail in the same view. Then watch the center target. It becomes smaller because the wider camera has to fit more of the scene into the same available image width.
Make smaller changes when choosing a setting
A large comparison helps explain the geometry, but it is not a recommendation to jump between the extremes. Once you understand the effect, open the full visualizer with the preset and move one value toward your current setting. Keep the aspect ratio fixed. Then test the candidate in the actual game, with your usual screen and seating position, so the choice reflects the way you play.
Camera references: horizontal and vertical conversion and view size at a distance. The worked examples use the visualizer’s own camera math.
How this is calculated
The center target at 120° is about 44% as tall as at 75° when both images have the same dimensions. That ratio comes from tan(75° / 2) ÷ tan(120° / 2), rather than dividing 75 by 120. The corresponding vertical angles are about 47° and 89° at 16:9. At a fixed camera direction, changing FOV rescales the existing image and changes the crop. Newly visible objects near a wide frame’s edges can look stretched because oblique directions are mapped onto a flat image.
Verdict
Use a narrower view if the larger central image is the effect you want to inspect, and a wider view if you want to examine more of the surroundings without turning. The preview cannot decide whether you aim better, feel more comfortable, or get a different frame rate. Those are separate questions to test in the game after choosing a small set of candidate angles.
