Oculus SDK v0.4.2 Beta Released

Oculus Rift DK2 Box

Version 0.4.2 of the Oculus SDK has been released for Windows and OS X today.

It introduces a new “Riftsaver” mode which turns off the DK2 headset when it’s not in use, reducing the possibility of screen-burn; adds a new chroma setting for improving chromatic aberration, and fixes the camera stutter seen in Unity-powered games.

Available to download today from the Oculus VR Developer Center, this free beta release comes highly recommended for everyone with an Oculus Rift DK2. Here’s the full change-log:

New Features:

  • Added OVRServiceLauncher Windows service, resolving the issue with the service not launching automatically on some systems.
  • Added a new chroma setting for minimum eye relief, improving chromatic aberration correction when configured through the Oculus Configuration Utility.
  • Added “Riftsaver” mode, which turns off Rift display in direct mode if the headset is not in use.


Bug Fixes:

Oculus SDK

  • Fixed an issue where the built-in latency tester would randomly stop working and the DK2 would have to be reset. This fix requires an update to the provided 2.12 firmware in the latest runtime installer.
  • Removed ATL references from the LibOVR Win32 Display code.
  • Fixed full core utilization of Oculus Configuration Utility when in Desktop mode.
  • Fixed the lag in Oculus Configuration Utility when the service is stopped.
  • Miscellaneous improvements to the Oculus Runtime Service (now called OVRServer).


  • Fixed crashes and corruption when using 64-bit client with 32-bit service.
  • Fixed NullReferenceExceptions due to script initialization order.
  • Fixed race conditions in TimeWarp responsible for camera stutter.
