My flat is quite dark and I often work at night. I also tend to like having dimmed lights. Cameras usually perform much worse in low lights.
I‘ve seen screen captures of people using the AVP in dark rooms and it looked really odd. Although, I guess the immersion mode could fix that.
Also, I know this is somewhat threspassing on taboos, but how come people write ten thousand word reviews about a new virtual reality headset without mentioning porn even once 😅
