mostly AC, GSC, R3E, rF2 .. Well there is only one correct FOV setting.. For you it is 31, whether it is the best one for you that is another question .. Set it to whatever feels good for you, but only one setting provides correct visual representation of track (perspective, distances, dimensions in relation to distance,...) and you having triple screen 31 must feel pretty goodUsing the in-game FOV settings are better IMO. What game do you play? Assetto Corsa, Project Cars, Iracing? Assetto Corsa's in-game triple monitor settings works well IMO. You calculate the distance from your eyes to the screen, angle of your monitors, etc. My eyes are 22 inches away from my monitor. Using Project Immersion my correct fov for Assetto Corsa is 31. I have triple 27's.
thanks i have done the calc and my fov was surprise not far of the standard but its still realy usefullhttp://www.projectimmersion.com/fov/index.php?m=1
personal preference .. Monitor sitting right behind wheel (it is on the wheel base) so I can see through the wheel the dashboad (virtual wheel off in game) but I can`t see bottom bezel of monitor .. distance ~51cm from screen, FOV with my 25 inch 16:9 screen is 35 give or take (calculate yours in that calculator .. on single screen it is sometimes good to go 2-3 degrees more than calculated) ...
