Is the IMU calibration tool still working (has it ever worked for this?) and given out by support?
Otherwise, what's the current way for (trying to) solve this?
Is an Oculus repair install also (trying to) re-calibrate like a complete de-install and new install of Oculus does?
Is a "full setup" from within Oculus trying to recalibrate as well?
Is this a software/timing issue or are there units which are more affected by left tilt than others?
Is there any metric in log files that could give an indication about how severe the tilt is?
Is there really no, even if "secret" way to add an offset somewhere to compensate for a few degrees of tilt?
