    I am looking for a VR SDK for Unity 4.5.5 which des not have the annoying drift.
    I tried Dive Durovis, Zeiss VROne, Fibrum. The latest version of Google SDK does not work well with my version of Unity.

    Can you help me??

    Are you using an IMU (accelerometer/gyroscope/magnetometer) to track the head position? If so, then drift is not up to the software as the hardware is incapable of avoiding drift. You can get a more accurate IMU and some clever software, but all IMU's inevitably drift over time. What you're looking for is a method of tracking which is absolute, as opposed to an IMU (such as in your phone) which is relative.

    If drift is that big of a problem, use an optical tracking system. This method will position your head with absolute precision over time.
