It's a catch-22. The motion sickness isn't a function of resolution or framerate (assuming a suitable framerate is realized). It's a biological response that won't go away until people develop a resistance. In the VR community it is referred to as getting your "VR Legs".
No, that's a complete myth. Some games are simply designed better than others on this front. Some games (actually many games) require absolutely no VR legs. Me and everyone else I've shown my Vive to have required no sort of acclimation, it just works, no motion sickness or anything. The reason for this is that in most experiences,
camera control never happens independently of your own physical movement. Most movement is teleportation, which is only mildly disorienting at first and causes no nausea. Anything that yanks your head around, like a rollercoaster or traditional game movement, that's what causes nausea. And there may be a bit of "VR legs" to that, but much of it is on the developers.
RE7 causes sickness because the devs have ignored all conventional wisdom about developing a VR game and jerk your camera around. VR legs doesn't fix that.
A more core issue of the PSVR in general is that having pretty much only one direction you can face, no turning around, means that they're going to
have to move your camera around or else leave you facing one way for the whole game. You can't for example turn 180 degrees in real life and point your controller toward a spot on the ground to teleport behind you. It loses tracking.
It's odd that Sony chose a sphere as the shape on top of the move controller. While working good enough to track it's position in 3D space, I'm assuming to provides no value in the small movements or rotation because a sphere is the same viewed from any angle. Had they chosen a square, triangle or something it could have given them something else for the camera detect and not rely solely on a gyro.
I don't have a complete understanding of how Move works, it's possible that the end of the sphere affixed to the wand is used as part of the detection. When a chunk of the sphere is missing in a certain shape, they know a little more about how the controller is rotated.
Otherwise I would worry that a partially-occluded sphere would be interpreted as a
smaller sphere, detected as being further away.
