More information about this release can be found here.

New Features

  • Full Support for Vulkan graphics API on Android devices, including:
    • Mixed-Reality Capture (MRC)
    • MSAA
    • Multiview
    • Fixed-Foveated Rendering (FFR)

Integration Changes

  • Updated the Oculus Unreal Integration to 1.39.

Known Issues

  • A significant drop in frame rate occurs when UE4 is not in focus in VR preview mode. To avoid this issue, uncheck the Use Less CPU when in Background in Edit > Editor Preferences > General (left sidebar) > Miscellaneous (left sidebar) > Performance.
  • Exclusive Mode issues: Setting the mirror window to full-screen exclusive mode will not work correctly if the monitor and HMD are connected to different GPUs.
