Head position randomly self-resets to an arbitrary incorrect position

By reducing settings I meant simply to see if that fixes the tracking issues. If it does then we need to dig deeper into priorities of resources.

It wouldn't really tell me anything, I need it to be repeatable for II start changing settings.

Late yesterday I jumped back into the same slot on the same mission and could not get it to fault no matter how I turned my head. I even tried changing the lighting in the room, it never missed a beat. As with most bugs there is a variable somewhere that is causing it but even if I think I am doing the same thing there is always likely going to be something thing different and that particular mix of variables is what is causing it. My own personal feeling is that it is the way in which DCS handles a the headset having momentary low/no/confused tracking. I will experiment with room light conditions but even this I am not fully in control of!

I am not sure how much the application handles tracking but simply hand it over to the headset software. Yes we can reset tracking manually but I would be surprised if DCS is resetting it sporadically, rather that the headset software layers be it Oculus, WMR, SteamVR, OpenXR etc. are updating the tracking info and sending this back to the application (DCS).

Of course it could be in the DCS code in which case I will be flat out wrong but my experience with other games has all come down to the headset and how its software copes with not getting a fast enough flow of data for tracking.

Well, I am assuming that the explanation of game/headset co-ordinates earlier in this thread is covering what happens. Now just need to see why it happens.

It may well be. My last experience of losing tracking was due to failing Reverb G1 cable. I never got this issue of the VR centre resetting, just the tracking failing to keep up (which was pretty nauseating!). This was many DCS builds ago so it is of course possible something has crept in. It could also be something different in the way that the Oculus software interfaces with DCS compared to WMR.

My experience with losing tracking in any game is that it is horrible, so even if the game assumes you haven't moved your head in the meantime I would be desperate to fix the loss of tracking but any solutions to better cater for it happening would be worth pursuing for sure.

Its not really lost tracking, exactly. I experience exactly what's shown in the video. More resetting randomly. Good for you if it doesn't happen.

I see. The op describes deliberately losing tracking to reproduce the issue so assumed it must be momentarily losing tracking when it occurs in game.

Please check
Untick use snap views in DCS options 

This seems to have fixed the issue for me! Long session yesterday and it was totally faultless!

Thanks

Update, seems it is not totally fixed after all. It is definitely linked to lower room light which is not something I have seen before. Maybe the change was on the Oculus side.

I had issues with my headset (Rift-S) loosing position a lot when overall light changed with v44 Oculus software. This didn't happen before v44 of the Oculus software, on pre v44 it only happened from as good as dark to fully lit. With v46 of the software (they jumped from v44 to v46), they seemed to have corrected that loosing position 'bug' under v44.
I guess you all are on v47 at the moment dealing again with the same problem that i had with v44. I'm still on v46 and i tend not to upgrade to v47 because of that (and because there's nothing in the updates for the Rift-S anyway anymore).

I have bound "recenter VR headset" from UI to a joystick combo just in case it looses tracking.

Anothering issue i found is that if you sit in front of the monitor like me, the headset is confusing its tracking information from the VR mirror on flatscreen. Since the position tracking of most headsets is also camera based, having the in game view in front of its cameras could confuse the software. I noticed this tracking offset happens much more frequently when i turn my head slowly.

Which is why i have to blacken my PC monitor once i start DCS to get a stable tracking performance. Another reason why i wish we could simply disable the VR mirror via options like in other VR games.

I have a brand new HP Reverb G2. I am experiencing the same problem almost every second session. The head/viewpoint can randomly move in the cockpit or many metres outside the cockpit with my real head not moving at all. This happens in the hangar lobby too. One second I am sitting in front of the DCS World Menu, then a few seconds latter I am at the ceiling of the hanger and then above the hanger. The headset seem to start jumping around as soon as I launch DCS. There is no such misbehavior of the headset when I am in the Mixed Reality Portal without DCS running.

I think it is a DCS response to a VR problem. For me on Oculus/meta/whoever it is definitely helped with good/strong room lighting and ensuring that there is always something for the cameras to see and use for tracking. It definitely wasnt like this before but I think it's manageable. Also uncheck use snap views in your game options. The point above about the monitor might also be valid it would fit, but I don't have one nearby.

DCS VR isn't working when you switch off the monitor

Same issue here, Quest 2
