MC-51953Almost instant motion sickness due to distorted rendering
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.

See MC-51953 for a full description.
The issue is NOT about FOV, NOT about bobbing, it is about DISTORTED rendering, as can be clearly seen in the youtube video:
https://youtu.be/yraaPpr3qGo
Especially notice the left and right parts of the screen; as the player is looking upward and downward, rendered parts are extremely distorted in a kind of sideways parabola.
Even looking at that video will give me extreme nausea.
It has been 4 years since I submitted the original issue, it was closed without a solution.
I still cannot play Minecraft without getting sick, just as lot of other people.
This was NOT happening when I bought the game; I could play it for hours on end!
Similarly, this does NOT happen to me when playing Skyrim or Oblivion; I can also play that for hours on end WITHOUT any problems.
Please look into this and come up with a solution.
UPDATE: 2021-07-10
Given that the original bug (MC-51953) was submitted more than 7 years ago, and was set to resolved, without actually solving it, and this bug has been multiple times been set to resolved and reopened again, this effect causing motion sickness for many people is apparently not important to Mojang/Microsoft. Sad.
Also it's amazing how many people keep repeating it's a FOV issue/pixel blurring issue/graphics card setting issue, while it's not about that. Even the YouTube video clearly showing the distortion effect near the left and right edges of the screen, saw a recent comment from somebody telling he saw nothing wrong with it. The issue is about distorted rendering which is most visible near the edges of the screen, and most visible for objects with straight lines that are close by.
This bug is related to MC-51953, which was never actually resolved. Original bug was "resolved" by increasing default FOV, but the screen distortion still persists, causing motion sickness and headaches for many players.
Environment becomes more distorted near the edges of the screen. Blocks appear stretched and warped the further from the center they are. This is easily observed by watching the corners of the screen as you slowly move the camera around. The blocks appear to "curve" slightly.
Does setting the field of view (FOV) to the lowest setting not achieve this?
Unfortunately, setting the FOV to lowest does not solve it. In previous versions I even hand-edited the config file for even lower values, but it did not give the desired result.
Would you be able to get some screenshots, or link a video to better illustrate your issue?
I've noticed this in every version of minecraft i've ever played. It's a fisheyed lens effect. The leftmost and rightmost 25% are stretched to double their correct width. I just always assumed it was the result of a 4:3 aspect ratio game trying to fake a 16:9 aspect ratio (by stretching the screen, but not in the middle 50%). Easy way to notice it is to turn so that the sun in the sky is on the leftmost or rightmost 25%. The sun will be twice as wide as it is tall. Personally it doesn't bother me that much, but if it's a bug (or just user error somehow) I'd love to get it fixed.
EDIT: screenshot attached. Also now that I look at it I find it hard to notice in places even when I know what to look for. The edge of that quartz stairs roof should be far enough along to be affected and yet...I guess it's just hard to see unless it's past a certain point (above 33% wider than tall?). Anyway the sun is all the screenshot is showing off.
EDIT 2: another screenshot to show the sun when looking directly at it. Huge difference.
Fisheye projections cause lines to be curved, which isn't what is going on here here. The unpleasant distortion seen with wider fields of view is a natural effect of a perfect rectilinear projection which can be seen in my attached screen shot with the two inset enlargements of trees, one from near the middle of the screen and the other from the edge.
Have you tried turning off the camera-bob effect in the graphical settings? Also try to dim your screen a bit and try that.
You're experiencing SimulationSickness, which you can get some pretty good tips from here: https://www.youtube.com/watch?v=CvimYs7tnRM
The video is put out by PennyArcade TV's ExtraCredits, and well documents the theory, and how to overcome it.
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?
I've experienced this issue in all versions of Minecraft I've used in recent years, and I agree with insomniac_lemon's analysis above.
The fix presented does not resolve the underlying issue with rendering the screen (i.e. increasing distortion of image dimensions, worsening the further they are from the centre), but only compensates for the distortion by drastically reducing FOV. Field of vision should not have to be sacrificed for less distortion caused by the rendering process, regardless of the screen's aspect ratio. This results in bad user experience in both cases.
I recorded a video in 5760x1017 on vanilla 1.12 with FOV set to normal (70) to show the dimensions of the blocks shifting as the camera pans:
https://youtu.be/yraaPpr3qGo
In the video, the trees and rows of stained clay on the left and right side of the screen are distorted to impossible dimensions. Although the effect is noticeably stronger the closer to the edge of the screen the image is, this is an extension of the issue already present on all aspect ratios (as opposed to being caused by a 48:9 aspect ratio). Changing the FOV to 30 doesn't quite "fix" the issue, but rather serve as a workaround to minimize the issue until it's no longer noticeable.
As others mentioned above, in other games I've tried running at this resolution, images on the far left and right are all displayed as they should be- Minecraft is the only game where there is distortion like this.
EDIT: This is the hardware setup used to record the above video: http://thgil.ganks.me/setup.jpg .
I haven't played Minecraft in years due to this issue. If I see the video of @thgilfodrol, I almost get instant nausea again, hence it does not seem to be solved. Show me any 1st person game that has this amount of distortion. This is still not acceptable.
@thgilfodrol
Can you maybe also post this video with the proposed FOV=30 that is proposed as a "solution" to this?
Is it possible to reopen a bug? Or do we need to make a new one?
I'd recommend making a new report. This one seems to be more tied to the FOV, whereas what you're describing has more to do with the way the visuals appear distorted the further they are from the centre of the screen. Please keep 3 things in mind. First, formulate the report in the format of a bug using the Bug Report Guidelines Here. Secondly, (for all reports including this one), please keep discussion around issues on the Mojira subreddit. Thirdly, be aware that it's likely the report will be closed as either invalid or won't fix, as this is on the border between bug report and feature request, seeing as new functionality would need to be implemented to combat the issue you describe.
Although this bug report is marked as fixed, the issue is only closed, but is not actually resolved.
I cant play minecraft since i came back to the game in October. I played it with no problems in February. Now, i get motion sickness immediately. Something changed. My wife gets sick too
It's probably due to perfect perspective that the game renders. There's no lens distortion at all and it seems unnatural for our eye.
Perfect perspective? Are you serious?
I can play Skyrim for hours on end, no problem at all, but get sick VERY quick when playing Minecraft.
Same with me - Skyrim and many other games give me no problems. Only minecraft causes me problems (and my wife) - and only since 1.13 (Bedrock)
Even the option to push the camera further away from your character might help - anything that reduces the amount of distortion on the periphery of our vision.
