Sim Racing FOV Calculator
The correct field of view for a racing sim is not a preference, it is geometry: the setting at which the picture on the screen subtends the same angle at your eye as the real thing would. Enter the screen diagonal, its aspect ratio and the distance from your eyes to the glass, and you get the horizontal, vertical and diagonal figures, so you can type whichever one your game asks for. The triple screen action adds the bezel gap and the side screen angle, and reports both the centre screen figure the game actually wants and the total view across all three. Measure to the glass from the seat you really drive in, because a couple of inches moves the answer by several degrees.
