Headbobbing and narrow fov can cause motion sickness. Your eyes are percieving the movement on screen, your brain starts thinking it's moving alongside, yet your body is sitting still in front of the tv or monitor.
Widening the fov can help, and reducing headbobbing also.
Once upon a time game devs decided that it would be more natural to play a character onscreen that moved and gave the same view as if you yourself was walking there, or running. It was then that more people started to get affected by it. Hence why many disable motion blur and ask for a wider fov.
And lets not get into the horizontal or vertical fov, but for the former a fov of 90 is desired. More will create a fisheye effect. For vertical a fov of 75 or 80 produces the same view, more will also create a fisheye effect.
Since console games are usually played on a big tv screen, a smaller fov of 65 isn't a real problem for most people, after all, you're sitting further away from the screen so your brain wont be disturbed too much, or fooled.
I had it with halflife, but not with css. And sometimes I fire up a new game only to be struck by it. Takes about 15 minutes and then I start feeling like I want to puke. Taking a short break also helps, if you do this in time, you might be able to return to the same game some 15 or 30 minutes later without any more sickness.
There are no medicine for it, no doctor can help, only if you have it all day long without even gaming or watching fast paced frames on a screen. Then it would be advisable to seek medical attention.
