In VR you can press a button to re-center the HMD to the game-camera position, this is a great and essential feature. It works fine.. BUT where it goes wrong: I noticed today in cars like WTCC, GTR3, LMP1/2 and probably every car (haven't tested) the head-position resets to something completely random sometimes. I noticed it the most on Suzuka and Mid Ohio, when there's a compression zone the head position changes drastically which can kick in some motion sickness. This has been happening since the most recent update. It's making the game nearly unplayable in VR because you have to keep re-centering the head position.
It's the Oculus Rift. I've tested my 3 sensors all one by one and all together. Doesn't seem like a sensor issue as it only happens in Raceroom, not when I play Elite Dangerous on my desk, or a roomscale game.
