Setup

• Start the VRG Tool service application
• Install the VRG OpenXR Runtime (see OpenXR page for details)
  • alternatively you can also run XTAL through SteamVR driver and use SteamVR as OpenXR runtime instead of the custom VRG OpenXR runtime
• Make sure that the VRG Runtime is installed and updated
• Make sure that the OpenXR Runtime is enabled
  • We also recommend disabling the SteamVR Driver
• Make sure that you have the correct Tracking option selected
  • use ‘IMU’ if you are using the XTAL internal IMU sensor without any additional room-scale tracking
  • use ‘SteamVR’ if you are using the Lighthouse/SteamVR tracking system

• Optional (if you are using room-scale Lighthouse/SteamVR tracking system)
  • Position the Lighthouse base stations around your tracking space, power them up, and make sure they are synchronized
  • Start SteamVR

• Go to Settings – Headset Resolution
  • Set the resolution to a value corresponding to the used GPU/CPU and your desired FPS
    • we recommend setting the main resolution to 30% and foveated resolution to 100% (with 45% vertical size and 30% horizontal size)
      • if you are using DCS through SteamVR, foveated rendering will not be available, so in that case we recommend setting the main resolution to 60%
    • make sure to restart DCS after changing these settings
    • you should test the resolution/FPS changes when the plane cockpit is loaded, as the main DCS menu will show overall higher FPS than what can be achieved in the full scenario

• Start DCS Launcher
• Select VR Mode and press the Play button
