I felt something similar couple of days ago. I had to stop playing even though I didn't want to.

If it happens a lot while looking at your PIP, OP, well there is an option to zoom in a bit, so you mostly see the display of it.

Don't know if that gets rid of the sway, but I think it does. The button for that option on the PS4 is the touch-pad.

That's all I can give you. Cheers.

I get headaches but thats mostly eye strain

It's like looking through a window, if you are far away, you expect to see little of the outside , if you are near the window you expect to see wider,, when what we see doesn't match up with our precieved feeling of how it should look we can feel sick..

interesting. Explains the weird very small vertigo when looking at my pip boy. In the Army we have a driver vision enhancement screen for vehicle drivers. The center of the image moves faster than the edges. We call it "warp speed effect" I have a cast iron stomach and even get sick from it.

I didn't think about why zooming in seemed better on the Pip Boy for me, besides being easier to read the text. But I think this may be part of it in hindsight.

I forgot about that. I will have to try that out. I like diet Canadian Dry ginger ale, so will try that.

The FOV is 70, correct? What have some of you who get motion sickness set your FOV to? Some guides say 90.

Do you sprint a lot?

I found that going back and forth from sprint to any non sprint mode, makes the FOV change (the tunnel vision effect), and that can be very nauseating.

I haven't figured out how to turn it off yet, and can't figure out why it's been added in the first place. I don't need the feel of speed when sprinting. It's not like I'm doing 60 mph or more.

Yes, I get dizzy playing this game. I wish I could zoom out the first person view like in eso. Never had this problem until eso and I played a ton of skyrim, fo3,oblivion, bf3,etc..

It's not terrible with fo4 but it gets to me at some point every time I play. I switch to 3rd person view periodically to combat it. Hopefully they patch in fov sliders and head Bob toggle.
