Setup

• Start the VR 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
• 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 OpenXR runtime is enabled
  • 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

• Create a startup shortcut forcing the OpenXR support
  • Go to your DCS installation folder
    • if installed through the DCS web installer this will be by default in ‘c:\Program Files\Eagle Dynamics\DCS World\bin\’
    • if installed through the Steam platform this will be by default in ‘c:\Program Files (x86)\Steam\steamapps\ common\DCS World\bin\’
    • if you want to use the multi-threaded version of DCS go to ‘bin-mt’ folder instead of ‘bin’
  • Create shortcut from DCS.exe
  • Edit the shortcut and add following parameters at the end of the path:
    • --force_enable_VR --force_OpenXR

• Start DCS using the custom shortcut mentioned above

• 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
    • 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
