GoogleCardboard SDK 0.5.2 Released

The GoogleCardboard 0.5.2 It's just released and it seams a great step forward.
It just solved all my problems with my LG G3. Now i can set a fraction of the resolution to get a 1980x1080 screen and the distortion filter is much faster with the unity's implementation.

v0.5.2 (10/12/2015):
- General performance improvements and CPU load reduction to reduce thermal throttling.
- New gyro drift correction method for better stability across more phones.
- Onboarding and Setup dialogs now support localized language strings. For Android this
is automatic. For iOS, enable Localizations in the Xcode project.
- Default distortion correction method is now done entirely in Unity to avoid
GL.IssuePluginEvent() overhead. The old native C++ version still available if issues arise.
- The GL.IssuePluginEvent() call uses a unique ID in order to be compatible with other native
plugins. (This only matters if you use the old Native distortion method.)
- A new CardboardCamera prefab manages both full screen clear and distortion
correction. It is included in CardboardMain, or created automatically if needed.
- Distortion correction is now done during the Camera rendering phase, which means
that uGUI Screen Space Overlays (and OnGUI) will appear onscreen now.
- The new distortion correction method is compatible with Metal (iOS) and multi-
threaded rendering (Android).
- The offscreen rendertexture used for distortion correction takes properties from
project settings (e.g. antialiasing, pixel format). Depth now defaults to 24 bits.
- The offscreen rendertexture resolution is padded to account for the barrel distortion,
in order to reduce relative fuzziness in pixels near the center.
- The Cardboard object has a simple slider to adjust the scale of the rendertexture
resolution globally. Dial down to increase performance.
- There is now an onscreen Back Button that functions like the normal Android back
button (which is hidden in immersive mode). You can turn it on or off, and choose
how to respond.
- Recent versions of Unity (5.1.x and 5.2.x) have changed the way they report DPI, which
is affecting the SDKs calculation of screen size. This has been worked around.
- A bug in the StereoController.AddStereoRig() function which cached the eyes array before
filling it in has been fixed.
