Setup

Simulators > Prepar3D > Setup
  • Start the VR Tool service application
  • Go to Settings tab
    • Make sure that the VRG runtime is installed and updated
    • Make sure that the SteamVR driver is disabled
    • Make sure that the display mode is set to Direct Mode
  • 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
  • Optional: Update the Prepar3D VRG driver to the latest available version
    • Download the Prepar3D VRG driver (prepar3d_hmd64_x.x.x.zip) [available in the Simulators folder]
    • Go to your Prepar3D installation folder
      • by default in ‘c:\Program Files\LockheedMartin\Prepar3Dvx\’
    • Unzip the downloaded prepar3d_hmd64_x.x.x.zip and copy its contents to the Prepar3D installation folder (overwrite the original files)
  • Start Prepar3D
  • Set your desired mission parameters and press OK
  • Select ‘Virtual Reality’ – ‘Enable Virtual Reality’ – ‘VRG’
  • If you want to use the foveated rendering functionality (recommended)
    • Select ‘Virtual Reality’ – ‘VR Settings…’
      • Change the ‘HMDDisplayMode’ option to ‘Stereo’
    • Go to Eye Tracking section
      • Change the ‘EnableFoveatedRendering’ option to ‘Yes’
  • Find the XTAL icon in the Windows notification area and right click on it
  • Make sure that you have the correct Tracking option selected
    • use ‘Internal’ if you are using the XTAL internal IMU sensor without any additional room-scale tracking
    • use ‘Lighthouse’ if you are using the Lighthouse/SteamVR tracking system
  • Open the Settings…
    • Set the resolution to a value corresponding to the used GPU/CPU and your desired FPS
      • If you are using the foveated rendering, 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 standard stereo rendering
        • for the XTAL 3 and XTAL 8K headsets we recommend using the default 60%
        • for the XTAL 5K headset we recommend using higher value (80-100%)
      • be aware that currently changing the resolution can slow down the rendering process in Prepar3D, so we recommend disabling and reenabling VR after each resolution change
  • The Eye Tracking features and MixedReality features can be accessed through the XTAL runtime settings menu (Eyes and Mixed reality pages), these features are currently not connected to any other similar functionality in Prepar3D menu
