Motion Sickness: Blurry images when rotating the camera?

[alandarkworld]

One thing I've noticed is that the images produced by this game are crisp and clear as long as you're standing still, but as soon as you move the camera just a tiny bit, the entire vision starts to blur. The faster you move, the more severe the blur becomes. Once you stop rotating the camera, it immediately reverts back to its normal, crisp look. I think this is the biggest contributing factor to the motion sickness I feel with this game. I did some back-to-back testing between this game and Skyrim (where this effect doesn't occur, and I can play this game for hours on end without these issues) to verify this.

And yes, before anyone asks, I have motion blur set to zero.

I suspect that Temporal Anti-Aliasing might have something to do with it. As all pixels on the screen change when the camera rotates, there is no temporal correlation between the images anymore (i.e. no pixel stays the same) and everything becomes blurry. Just a working theory though. Maybe the devs can confirm.

Sadly, all anti-aliasing methods provided by the game seem to be based on temporal methods in some way, so I can't tell for sure.

Has anyone found a solution / workaround?

Other ways I've found to reduce my motion sickness:
- FOV: 60 (I can't seem to handle this fish-eye effect caused by higher values, even though some people said it's better at 120, I definitely cannot confirm that)
- No motion blur
- head bobbing off

The usual culprits are the "Effects" or "Post Processing" , I always turn them off in all games because they make the image quality way worse. Try setting them to low or medium.

The game forces TAA on, so even if you disable upsampling (which definitely enhances your problem) you will still get that smearing effect. I doubt it's anything related to post-processing if motion blur is already disabled, except maybe chromatic aberration, which I haven't noticed in this game.
Also, while I understand that the fisheye look from high FOVs may cause motion sickness, low FOVs can do the same. 60 is quite extreme. I usually choose around 110 (horizontal) in first-person games, but you could try something like 80-90.

Blur is a side effect of TAA and is used to hide some graphical artifacts. There's no option in the game to disable TAA, and upscaling will only make it worse.

The best option to try is DLAA if your computer is powerful enough. It's not perfect but every other option is worse than that.
