90 isn't really a narrow FOV, though I know some like higher than that. Usually games with low FOVs people complain about are like 65-75 FOV. 90 ain't bad. I usually use 95.

I would guess default was like 75, I changed mine to 90

Thank you for sharing :)
By the way the default FOV is 65. Default FOV in Fallout 4 is 80, and that was quite ok for me. Too high FOV gives a fisheye feeling (but it all depends on screen proportions).

90 is default good value for 1080p...I use 100

90 at 16:9 is the same as 75 at 4:3, which is what a lot of PC games used back in the day like Deus Ex and Morrowind. I think people usually look at id games like Doom and Quake which used 90 at 4:3, which is 106 at 16:9, but those games were designed around that higher FOV. I don't think it works with most modern games at all, personally. Looks too fisheye.

I'm on a 43" panel 1080p so for me 90 - 100 is good
