I have been trying Rift S for about a week now. There seems to be a slight screen vibration or something weird that makes me feel uncomfortable. I dont have the same feeling with Rift CV1. Does anyone else feel this? Seems to help if I use my hands to secure the bottom of the headset to my head better. I suspect it might me micro movements that the inside out tracking might not be able to compensate for but I dont know really. I still have a few weeks before my return window closes. I hope if it is a known issue, that there might be an update by then. Until then I just went back to my Rift CV1 and will probably send the Rift S back.
I have similar issues that seem to be tracking related. A lot of jittery tracking movement even when my head is stationary. Sadly I don't have a CV1. My Rift S is replacing a mothballed DK2 that I only ever used for work.
Same thing here. It may need a well lit room to benefit from full tracking precision. At daytime it seems to be less annoying. Maybe we have to ad some lights to our gaming room...
