      Description

      Since about version 1.6 of Minecraft, I know of several people including myself that suffer from instant motion sickness when playing minecraft.

      I'm almost 100% certain that it has to do with the video rendering. In most situations it is clear that the video rendering produces a distorted image. This becomes most evident when the player stand in a 90 degree corner in a canyon, and very slowly turns around. It can then be clearly seen that the walls of the canyon move in a non-linear motion. It is this distortion that most likely produces the motion sickness.

      For instance, I'm able to play serveral first person games such as Oblivion or Skyrim for hours continued gameplay with no motion sickness at all, including movements in "tight spaces". And on the other hand, some older First Person games that had render "optimizations" and thereby also a non-linear distorted view, produced the same motion sickness.

      The result is that I had to stop playing minecraft altogether, which is a shame.

      Could you consider adding a render mode that produces acurate rendering? Most likely that would prevent motion sickness and enable people sensitive to it to play again.

          I always turn camera bobbing off (it does make the nausea indeed worse). My screen is not overly lit in comparison with the room. I use the same viewing conditions to play Skyrim for hours without any problems at all.

          I will try to upload a video of the effect as mentioned.

          In my experience I suspect the cause of the nausea is the distortion that happens when looking at things at the side that move towards the middle that give the unpleasant experience. I do not see such distortions in games like Skyrim.

          Smells like our default FOV is too high.

          AND NOW I CANNOT UNSEE IT! WHAT DID YOU DO!!!

          ARGH

          Fixed by allowing lower FOV values (30 lowest now). Will get backported to 1.7.6!

          Bored, so i did the math.
          reccommended FOV = 2 arctan ((width of screen) / 2 * (distance from computer))

          If you get lower than 70, then there is a problem.

          I have also noticed this, with higher FOV values, things in your "peripheral vision" stretch.

          Lowering for FOV isn't a catch-all solution, because it really does limit what you can see, as if you're looking through binoculars rather than "seeing through the player's eyes". Most other games don't have this issue (games at 90 FOV and even Quake don't seem to look like they're stretched out), so I'd say that Minecraft likely only changes one dimension of FOV, keeping the other one at the same value.

          Chances are, this is a teeny issue that was made back when notch was the only one working on the game (also note, the reticule is also not centered on the screen, likely also an old issue, I have a bug report for that) and nobody seemed to notice. Maybe you could take a look and see what's going on with the FOV, Grum?
