Important note about settings

If you have been referring to Varjo's Getting the perfect image quality page in order to understand the various resolution settings in Varjo Base, please beware that the values from table 1), 2), 4) and 5) "running a Varjo native application with foveated rendering" and "running a Varjo native application in quad view mode (fixed foveation)" are not applicable. When using Quad-Views-Foveated's implementation of quad views rendering, Varjo Base will "see" your application running in Stereo mode, and therefore use the resolution settings from table 3).

If you use Varjo OpenXR...

• To make sure you are using the Varjo OpenXR runtime, open the Varjo Base application on your PC, then in the 'System tab', under 'Compatibility' toggle 'OpenXR' to on.

  • While in that tab, ensure that eye tracking in 3rd party applications is enabled, under 'Privacy', toggle 'Allow eye tracking' to on.

  

• Ensure that your eye tracker is calibrated. In the 'Headset' tab, under 'Foveated Rendering', make sure to select a method for using calibration.

  

If you use SteamVR OpenXR...

• Follow the instructions to install OpenXR-Eye-Trackers.
