I've noticed that the camera sits slightly forward of the point it rotates around (or does that depend on FOV?), so could it be related to that, and could a mod make it an adjustable option? Also, at higher FOVs, the view towards the screen edges is distorted a fair bit, so could a shader subtly adjusting the curve of the FOV help?

I bet either or both of those things could be the problem...

"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."
Not the most hopeful answer, but an answer it is.

That's not a bug, that's basic projective geometry. That's how perspective projection works.

You know what, I'm pretty sure that your motion sickness is because your FOV is too high. To have a perfectly non-distorted view, you need to adjust your FOV to the exact value of the angle between the top and bottom edge of your computer screen (measured from your eyes), because that's what FOV means. If your FOV is set to that angle (or alternatively if the angle is changed to the FOV value, by moving closer to the screen), if you close one eye it should seem like your monitor is literally a Portal-style portal into the virtual world behind it, with no visual distortion. That's because that's literally the exact calculations your GPU does.

EDIT: Need another intuitive explanation? Suppose you imagine the sun as a square sticky note in meatspace, circling your head and always facing you directly. If you hold the sticky note in front of the center of your computer screen, it will block a square area of your screen. If you move the sticky note (rotating it around your head) so it blocks the right edge of the screen, it will cover a "rectangular" (more like trapezoidal) area, and that area is bigger than the other area. If you move your head closer to the computer screen, this effect will become way more pronounced.

Now imagine you make the sticky note half as big, but hold it half as far away from you. From your perspective, nothing changes visually (except some lighting), and the sticky note will cover the exact same pixels it did before you scaled it, no matter where it started.

Now imagine you make the sticky note 1234567x bigger and hold it 1234567x as far away from you. Now it should be waay behind your monitor instead of in front of it, so the pixels that used to be blocked by the sticky note are now exactly the pixels blocking the sticky note instead.

Now remember that 3d rendering is made to look like a completely undistorted window into the world ((if your FOV is set correctly)), so if you move the huge-ass sticky note into the virtual world at the same relative position as it was in the real world, those pixels blocking the sticky note are now exactly the pixels displaying the virtual sticky note! And that's why the sticky note is rendered askew when from an angle.

tl;dr: Your computer is doing everything right, but you liar told it that you're sitting like two inches away from the display. Don't blame the computer.

EDEDITIT: I can't believe nobody in that bug thread realizes this isn't a bug. Everything is working perfectly as intended. Even that 5760x1017 video looks exactly as it should look according to projective geometry. The only issue is that the fella isn't close enough to his computer screen.

I lowered my FOV to crazy levels (all the way to 30 from 70, with multiple stops along the way) and it is still an issue. Like I said, other games (where I leave FOV at 70) are perfectly fine.

[MagmaMcFry]

In that case, maybe the nausea issue is not what you think it is. Maybe your look sensitivity (inches/360°) is just slightly different in Minecraft than in your other games, and you're not turning as much or as little as you expect to be turning. There are online mouse sensitivity calculators that can convert between sensitivity settings in various games. Take a game you're comfortable in and transfer sensitivity from there.

Alternatively, maybe it has to do with how Minecraft receives mouse input. Some games use raw mouse input (how much the mouse actually moves) to determine how much to change the view, but others only read the change in cursor position, and that change in cursor position is affected by Windows' mouse acceleration filter. Do you have mouse acceleration enabled in Windows? If yes, then you should probably turn it off forever and get used to that, because mouse acceleration is nonlinear and evil. If you don't know whether you have mouse acceleration enabled, then you have mouse acceleration enabled because Windows is evil by default.

I'm sure minecraft does that. I've clicked out of the window multiple times due to me dragging the mouse away from the re-centered middle it keeps pulling the mouse to to move.

[MagmaMcFry]

Yeah, that's how the old LWJGL does it (recenter cursor every frame, and just check how far the cursor moved away from the center in between frames), and Minecraft is based on LWJGL.

Remember how I said I used to be able to play fine? Well I when back and tried 1.2.5, and it was fine. No real problem.

FOV at the default (70), mouse sensitivity turned down a hair, view bobbing off. Same settings in the latest version induces a headache in no time flat.

I tried 1.5.2 and that seemed mostly OK too, but maybe a little worse than 1.2.5

Okay that's just weird then. Try setting your updated instance's FOV and sensitivity to your 1.2.5 instance's FOV and sensitivity, then try toggling vsync or headbobbing or both, those are literally the last remaining things I can think of that would change anything.

You should see a doctor about it. I don't think changing settings will help.

[forsaken1111]

Yeah this sounds neurological rather than software based. I went back and moved around in both versions, old and new, with the settings as close as possible and couldn't see a difference.

Anyone here checked out Vintage Story? I just heard about it today. Seems to be a Terrafirmacraft inspired minecraft clone.

Briefly talked to the developer on discord. Its an interesting project that's very heavily inspired by terrafirmacraft but improves upon it in many ways.
Meanwhile my custom server continues to be delayed XD

[Mephisto]

You might remember me as either that guy with the massive Immersive Engineering/Petroleum setup or that guy who fucked up the Vintage Story server.

Well, I've dropped out of the server game for now and have been slowly working on the following.

[Paxiecrunchle]

amusing to read the very beging of this thread now given how much the game has changed over the last nine years. Also PTW.
