For me there was practically no sickness at all, first time I used the headset I felt a little weird after an hour, and after that had no issues playing a variety of genres, with no teleportation.

Okay except that one time playing COMPOUND. By accident I moved the analog stick to the left while turning my head to the right, and the image moving the opposite of what I expected made me feel bad. I finished the level there, and then had to go rest for a couple of minutes and stop playing VR for the day.

tl;dr for some people it almost never happens, until it does.
