A:AnswerIf you’re talking about sensors like the old Rift that you would place on your desk that looked like mini speakers, it doesn’t come with any as they are no longer required.
A:AnswerThe short answer is yes. Although, you could use rechargeable batteries and swap them out when needed. I also hope a chargeable set of controllers is being developed.
A:AnswerA 1080 gtx card should have multiple hdmi/display ports; just plug the cable into one of the display ports (just a note, try for one that is not next to an used port; I had a connection issue due to the hdmi cable and display port cable not having enough room between themselves). For the usb cable, it strictly needs an usb 3.0 connection. After that, just download software and folow instructions!
The 32gb and 64gb are on-board starage capacities which, don't quote me, I think are only on stand alone VR head sets (ones where you don't need a computer) and has no relation to the rift S. The rift go is the one that needs on-board storage.
A:AnswerThe Oculus Rift-S tracks the headset and the hand controllers. I heard that work is being done on "Body Attitude" (laying, kneeling, standing) is being developed.
