Micro Stutters / XrNeckSafer

[Nedum]

Hello everyone,

I would like to share with you an important discovery I made regarding micro stutters.
It may already be common knowledge, but I couldn't find anything about it in the forum, which is why I'm starting this thread in the PIMAX section. This may be a problem that only occurs in conjunction with the XrNecksafer and the PIMAX software.
My OG Crystal kept to start stuttering when I looked to the side, and then stabilized itself, even though the FPS and frame times were consistently high enough to not get any stutter at all.
After switching from the 4090 to the 5090 with its better raw performance and significantly higher FPS, I was surprised to find that the slight stuttering in some situations and maps was still exactly the same as before.
Until then, I had assumed that it was due to the poor performance of the 4090, so I didn't look into it further. Now, I was sure that it had nothing to do with the GPU.
So I tested what was possible, but always with XrNeckSafer enabled. It never occurred to me that this great tool could cause a problem. It never even crossed my mind that it could be due to this tool.
Then I've got my Crystal Super and this Crystal Super had a few major problems, and in order to test everything properly and rule out problems with third-party software, I disabled all tools.

I was surprised to find that these mini jerks when looking to the side had completely disappeared. And not only that, suddenly the image was still smooth even when I had FPS dips way below 72 FPS.
At first, I thought I had reset the setting, but that wasn't the case.
So I enabled each tool (Quadviews Companion, OpenXR Toolkit, Quad-Views-Foveated, and XrNewckSafer) individually, and as soon as I enabled XrNeckSafer, the stuttering started again. 
It seems as if XrNeckSafer prevents the “smoothing” of frame times, which is normally handled by the manufacturer's software.

It may be due to how I configured the XrNecksafer (see image below), which is why others may not notice this effect
If anyone is using XrNeckSafer and experiencing mini-stuttering when looking to the side, even though the FPS and frame times should be sufficient for smooth display, I recommend trying it without XrNeckSafer.
For me personally, it was an eye-opener.

So, with the Pimax Super's FOV, can you do without XRNeckSafer?  I planned to use XRNS with my as-of-yet-undelivered Pimax Super 50PPD Ultrawide, so I am curious.

@Dawgboy Yes, but still not as good as with Necksafer. I have to move my body more to get a good look behind me. Even with the Crystal Super, you get not the big FOV view you have in RL. But now I can see the first part of the wings and the tips of my loadout of my F16 without XrNecksafer and without moving my whole body. 

Edit: You ordered the Wide FOV version. You will perhaps see the whole wings with only moving your head at the edges of the lenses, but you still have to twist your upper body to get a good look behind you.

@Nedum

I suspect that the smooth autorotation might be the issue, since XRNecksafer would then need to continuously change the view position.

You might want to try with Snap rotation.

Yeah, I think that's the problem, but I can't go with the snap rotation. I tried it a few times. It feels completely wrong. That's probably why it makes me feel sick. Not my world.

I do not think so, from experience in Pimax 8kx with 160deg horizontal. As you do not see outside of HMD sweet spots, it is hard to just turn your head enough. Except with swivel chair, and maybe hand rudder (no pedals) - if that suits you.
