Interesting, I thought having a too large FOV would result in motion sickness. Which is why when running you might reduce it, to compensate for the faster movement. I guess to clarify, you're mostly talking about PC gaming where you're sitting close to the screen, or is this something you also experience with console games?

In VR, one method of reducing motion sickness is covering the edges of the screen during movement to reduce motion sickness (a temporary tunnel vision effect), essentially reducing the FoV. I suppose playing in windowed mode would be similar :P
