Oculus Release Notes

Oculus Minimum Specifications

Please refer to the official Oculus recommended specifications here.

Setting Up

  • Opt-in to the beta branch.
  • Ensure the new Oculus runtime is installed (Download).
  • When launching Monstrum from the Steam library, select the Oculus mode.

Optimal Gameplay Experience

To reset the Oculus orientation on the keyboard press the left square bracket or press down on the right analogue stick of the controller.

For those who experience performance issues whilst Oculus mode is enabled, we suggest:

  • Turning off V-sync
  • Enabling Vertex Lit rendering. This should boost performance considerably, but will create some unusual lighting artefacts. Use with caution.

Known Oculus Issues

  • Black flickering/blinking in the right camera lens. This is a known graphics driver issue. We suggest you take the following steps if you encounter this issue:
  • Restart the game.
  • Restart your computer.
  • Switch off Vsync.
  • Turn on Vertex Lit Rendering.
  • The Oculus Team suggest following these steps.
