@JoeJ Just noticed that I failed to reply and commented instead, so you can find my reply down below :D

@JoeJ Yeah, for 3D games the fov is probably too small, except maybe if you are sitting really close in front of a large TV. So, when your game is not specifically tailored towards this feature, it is probably a bad experience. I could imagine that if you have a simple game, you could move everything “in front of” the monitor, so you do not use the monitor as a “window” to a virtual world, but let the world exist outside of the monitor. As said this would only work for extremely simple games, maybe a 3D pong not games with complex worlds.

I experimented only a little bit with an artificially altered fov, it still kind of worked, but everything looked bigger/smaller than its actual size, so one might get the same effect by just scaling everything down, but I did not compare it directly.

Sounds like a super fun experiment you did, very cool that it worked, but I can imagine the eye strain :D I completely ignored the stereopsis effect for now, so the shown effect actually works better for a camera as it has only one “eye”. You can always solve this problem with shutter glasses and rendering alternating frames but I would love a solution that does not require you to wear any devices, even if it is a little less effective then.
