Sometimes when start using my headset the world is not level. The whole world is tipped like the funhouse at the fair and it carries over into games.
Note: Not floor height, the slope.
Sometimes unplugging my headset and plugging it in again fixes it, but sometimes I have to restart my whole computer. I can live with, but if you could make an app where I can set the headset down and click a button to recalibrate it would be much appreciated.
