If the FOV can be changed put it a bit higher (i get that same headache when the fov is at 60 or less, like the first metro)
Simply put, Screen sickness is a bit more common than what people think. There are many things that bring the problem up :
- The fact that screens uses a number of frame per second is a factor (might not be the exact source) which affect how much fatigue the brain gets from analysing the information. For some people, the brain even turn down other senses to allow itself to analyse all the information from a screen.
- This wasn't something common back in the days, but now some people are getting "too used" to the 2D factor of a screen. For some player, their brain is so focused on the content of the screen that it might even stimulate what it thinks it's seeing. For example, the brain "complain" to the ears system (which also is the area which determine your orientation) that you're in "that space/area" while the ear complain that it's not. This bring a kind of motion sickness even if the player is not moving. (Even if the player know that it's fake and not a real space, the brain sometimes don't get it itself as it's "too much adapted" to the thing. This is due to our changing way of living which, today, people are getting too used to digital screen up to the point that they don't see them as screen anymore.)
- The FOV ("field of vision" for a living thing, "field of view" for a simulation) is also something that can bring a motion sickness. Even if just a bit slightly, every person on Earth got a different field of vision based on their eyes as well as tools used to see (glasses, googles, etc.). The video game create a fake field of view. Normally, a human should see at least 120 degrees in front without any problem (if you include the "partial vision" or "unfocused part" which is the blurred part of your view, it's around 170 degree of vision. For people with glasses, it's around 100-110 degree depending on their eyes and size of the glasses.) On a computer or in a game, it force the player to focus on only 60-90 degrees. The options to change the "FOV" in a game is actually to make it so that this focused 60-90 degrees is changed to something closer to what the eyes are naturally adapted to by stretching/compressing the picture (so that the 60-90 degree might stay the same "size", but allow the brain and eyes to analyse 120-135 degrees of informations.)
Best way to describe the things is if you look throught a bowl made of really great transparent glass. That's "forcing" your vision to become "wider" or "compressed" (depending on the side you look throught). If you get sick while playing a game, it only means that your eyes and brain is not adapted to the deformation of the information they analyses together.
There are some possible fixes :
- Changing the Field of View if possible.
- Adjusting the resolution the monitor (screen) display. As stupid as it might sound, close to half of the PC users in the World don't even uses the actual screen resolution they should uses normally. They take what they "feel better" with and, in some case, it's totally stretch the view in one direction. (One big example is those who uses a 16:9 screen which should normally be limited to 1600x900 or 2560x1440 and force it to something like 2560x1600 at a ratio of 16:10 because that "more pixels in the screen" so they think of a better resolution. That's crap and they are killing their eyes and damaging their brain by adapting it to false informations.)
- Uses multiple monitors. By using, for example, 3 monitors whenever your hardware allows it, will help you to reach the actual degree of vision in one direction (at least) and will reduce the "glass bowl" effect on your brain.
The screen sickness...hmm if this is, then is there any way to relieve the symptoms? Right now 600 mg of ibuprofen is kinda helping but not enough.
Seriously though, i had the same problem years ago with doom and such titles. Sitting a bit farther from the screen helped a bit but not completely. I really stopped playing it.
The next generation of shooters,like quake, didn't give me the same troubles...phew! *g*
Multiple monitors as donoghu proposed might help too, i didn't try it but would test it out somewhere before buying the monitors.
Eating more Ibuprofen just for a game is probably not the best idea. ;)
Perhaps someone knows a better solution though... i would be interested too and could perhaps finally finish doom... :)
In my experience poking around google or asking people is sometimes better than doctor visit.
"As astronauts frequently have motion sickness, NASA has done extensive research on the causes and treatments for motion sickness. One very promising looking treatment is for the person suffering from motion sickness to use either a strobe light or LCD shutter glasses that create a stroboscopic vision of 4 Hz with a dwell of 10 milliseconds."
Short conclusion on the NASA research:

A strobe light should be cheaper than a monitor. :)
It does not help 100% either though, but helps as it seems.
If you have no other serial diseases (like infections) and this sickness only comes up, when playing these games, then in most cases it's a simple disturbance of your balance system - just as mentioned before, your vestibular system[en.wikipedia.org] in your inner ear, that's responsible for analyzing your actual velocity in the three dimensional axis delivers opposite "values" for motion to your brain than your eyes do.
For further information:
- Equilibrioception[en.wikipedia.org]
- Balance disorder[en.wikipedia.org]
- Motion sickness[en.wikipedia.org]
The good news is, that this kind of motion-sickness only comes up when the player feels strongly as part of the game - the so called degree of "immersion".And just a last tip - for your livers sake, stop taking this massive dose of ibuprofen.
Hey I just popped in to say that this problem is a lot of just not exposing yourself enough to this kind of visual sensory input. Fighter pilots don't throw up, but their inexperienced passenger may. You just have to build up to it bit by bit until your brain knows how to handle the information.
Lighting is awesome in this game and its truly immersive.. one of things that bring that immersion is your movement and breathing movements.. do you thing it might be related.
Another point.. i find orienting in 3d space very "uncomfortable" and i find myself defining directions on my own.. but whenever i think of some way to exploit 3d space that breaks those set of directions (like park a ship on "ceiling" of hangar) its like i have to overcome slight discomfort.. might that be part of it? that the game breaks of pecpetion of space?
...for example i installed another grav. generator at the bottom of my base so i could walk there ... it was weird wherenever i went there... i should have fall down isted i walked upside down..
