To the OP's point about the autofocus making him dizzy: I don't know what to tell you man that's honestly one of the biggest selling points for me with HereSphere. When I have to adjust the horizontal shift to accommodate when scenes go from far away to close up views, it's a big pain in the ass.
Another thing HereSphere does that I really like is it's ability to adjust the viewing scale of the video to match the camera it was shot/encoded with. A lot of times you'll have a video that looks absolutely dogshit in almost every format except for a handful that match the specific fisheye or wide angle lens.
Lastly HereSphere really nails 3DOF. Yeah DeoVR has it too, but it just feels much less responsive, less accurate, and more restrictive.
DeoVR is great don't get me wrong, but these technical features really add huge layers of immersion to the viewing experience.
