Why FOV in GW2 is so good?

@Avelione.6075, I'm really glad you're having a good experience with the game in this way. I have been asking around to see if I can find some insights that would give you more information on why it is like this--and hopefully improve this for you with other games--and our Lead Engine Programmer had some insights to share: Disclaimer: I'm not a doctor, so this is just my conjecture. My understanding is that discomfort often stems from a mismatch between what acceleration you see and what acceleration your body expects to feel (think reading a book in the passenger seat of a car). This often happens in games with tight camera control and frequent camera rotation. Think of the difference in visual experience between an over-the-shoulder action game vs. a game with a fixed isometric perspective. GW2 generally has center-focused action, allowing the camera to zoom out and maintain a relatively stable perspective. Since video games project a 3D world onto a flat screen, high FOV settings can introduce unnatural motion at the edges, which can be bad. This is the fish-eye effect you mentioned. IMO GW2's design allows the action to be happening such that the FOV can be tighter and still fully playable. As an example, FPS games (and a lot of modern third person perspective games) tend to incentivize really widening the FOV (to see more stuff) which just makes this worse. Additionally, I believe discomfort can come from input lag or camera motion that doesn't align closely with player/camera movement. GW2 has a pretty direct relationship between player input and camera movement (maybe with the exception of some mounts), which probably helps. As to your question about applying this to other games? I'd say the game design is more relevant than any graphics settings, so the best I could suggest is zooming the camera out more and tightening the FOV if those settings are available. Hopefully this sheds some light on the situation for you. Take care!
