It really depends on the person and the hardware. I’ve seen people with PC-VR setups that get sick, but are 100% okay with wireless. I think it’s an issue of FOV, FPS, and overall just getting used to wearing a big box on your face.
I see a ton of people shitting on VR because they get sick, saying that it’s just a gimmick and it’ll pass. I think it’s a neat piece of tech that deserves to get better, hopefully the issues will be ironed out over the generations.
