I believe some driving sims support extra wide field of view so that you see the sides of the car interior. I’ve seen that with a multi monitor “curved” set up but I’m not sure if a true curved monitor is curved enough for that illusion. Mine is pretty subtle, maybe 15-20 degrees total

it's not just the aspect ratio - the perspective is different on curved monitors, because the surface is pointing in a different direction at every point. you have to simulate this with an effect related to the fish-eye lens.

That's been my experience for the few games I've played with that had field of view settings with some semblance for curved monitors: things towards the far edges balloon larger like with a fish-eye lens, which turns out about what you need to best activate peripheral vision too.
