I ordered the rift+touch bundle last week, the hardware arrived today. Installed and used the Rift fine yesterday, but today I notice that my horizon (the part of the world that is supposed to be level) is slightly tilted down to the left. It's not very noticeable in games with lots of movement, but in the Oculus VR Home screen (where you see the white whiteframe) it's visible. Tilting your head to the right obviously doesn't work, because the sensor thinks that whatever it's showing is level
I read up on this, and it seems to be related to temperature issues with the IMU. The effect is definitely not as outspoken every time I use the Rift, but it annoys me enough to care....
Anyone else experiencing this behavior?
