I have some view shifting too. Sometimes in DC VR. After a few races I'll have to sit slightly angled on my couch to watch straight out the car window. I also sometimes slowly sink down behind the wheel, yet that can be reset with a simple options click. You can't reset the 'north' position afaik. Maybe turning the headset off and back on could reset it. It's the same in other games where you have a clear 'north' position to look to. I'm sitting a bit too far from the camera though, right at the 10ft edge.

I've also had a few times where the headset turns all black for a second, then comes back on. It's only happened a couple times in 40 hours of play time, very disorienting. And twice I had rotational tracking not work at all, but I think that was from turning the headset on out of view of the camera. It could use a stability patch :)

I use the old (square) camera, sitting under the tv aimed directly at me.

thank you very much for sharin your expierence.

I did some more research and some people really think its the camera fault (its not official confirmed by sony yet).

The reason should be that the distance between the two camera lenses from the ps4 cam are in some models to far from each others (just a milimeter would cause tracking issues). The PSVR software is set to a specific distance to measure your location but if that distance is just a little bit off, it causes troubles. Ill replace my camera next week and will see if its helps.

If thats really the case this should be fixiable through software though. The distance just needs to be adjustable to correct the measurement

I hope that helps but I think it's an inherent limitation of the system. Gyroscopic drift can never be completely eliminated. Adding a magnetometer sensor in the headset might help yet that's not super accurate either. (psvr only has 3 axis gyroscope and 3 axis accelerometer)

When you turn the headset on it assumes you're looking at the camera and calibrates that as the 'north' position. Likely in the screen that tells you to put your head inside the square of the inverted video feed. It can determine the level position pretty accurately by measuring the changes in gravity experienced by the 3 axis accelerometer. However the gyroscopes will drift and need to be slightly adjusted all the time.

The camera does this by looking at how the pattern on the headset changes, attempting to both infer distance (dots getting closer/further horizontally and vertically) and rotation (dots getting closer horizontally looking left right, or vertically looking up down) The accelerometers can help with looking up and down, they can't when looking left and right.
The further you sit from the camera, the smaller the oservable changes, the less the camera can help combat gyroscopic drift.

The only way to completely fix this is if the headset tracks a fixed point (like the wii mote). psvr can't do this, no camera or anything else on the headset. However it should work better if you move the camera closer for sit down cockpit type games. Time to move the coffee table back into the livingroom.
