Supported headsets
The option to enable Eye Tracking will appear in the menu if and only if your headset and headset driver can support it.
See Supported headsets / Eye tracking feature.
Using Eye Tracking Foveated Rendering
The use of Eye Tracking (ET) in conjunction with Foveated Rendering (FR) can greatly improve performance with minimal loss of visual quality.
In addition to the requirements for your graphics card and headset, it must be possible for OpenXR Toolkit to distinguish when the application is rendering the left and right views. This is not possible for all applications, and therefore eye tracking might not be offered for all applications. When not available, Fixed Foveated Rendering will still be offered as a fallback.
Below is a table of games tested with eye-tracked foveated rendering:
| Game | Note |
|---|---|
| Assetto Corsa Competizione | Requires OpenComposite |
| Contractors | Requires to add -hmd=openxr to the command-line |
| Fallout 4 VR | Requires OpenComposite |
| Ghosts of Tabor | |
| Hubris | |
| iRacing | Requires OpenXR mode |
| Microsoft Flight Simulator 2020 | |
| Pavlov VR (Beta) | |
| Praydog’s UE4VR Injector | Mod is not yet released |
| The Elder Scrolls V: Skyrim VR | Requires OpenComposite |
Most Unreal Engine games using OpenXR directly (not OpenVR) should work, since Unreal Engine uses a rendering technique that allows left and right eye to be identified at rendering time.
Considerations for Varjo
Varjo supports eye tracking for PC applications when using Varjo as the OpenXR runtime. If you are using SteamVR as the OpenXR runtime, this runtime cannot support eye tracking for PC applications.
You must toggle the Allow eye tracking option from the System tab of the Varjo Base software:
Click for details...
This option must be enabled for OpenXR Toolkit to access the eye tracking data for its own implementation of Foveated Rendering.
Considerations for HP G2 Omnicept
In order to use the eye tracker on your Omnicept device, you must first install the HP Omnicept Runtime.
Once installed, please run the HP Omnicept eye calibration application.
You must then allow applications to use the eye tracker. You can enable all applications by disabling the Require user approval for Omnicept clients using sensor data option under the Omnicept Client Approval Settings in the HP Omnicept software:
Click for details...
Toggling Off the Require user approval will allow all applications to use the eye tracker.
You may otherwise selectively allow applications, one by one. You must first run the application once, enable eye tracking in the OpenXR Toolkit menu, then open the HP Omnicept software and allow the client, under the Clients tab, in the Incoming subscriptions request table:
Click for details...
You can Accept Incoming subscriptions requests to selecting allow an application, while forbidding others.
Considerations for Quest Pro
Oculus Quest Pro only supports eye tracking for PC applications when using Oculus as the OpenXR runtime. If you are using SteamVR as the OpenXR runtime (for example, to use Virtual Desktop), this runtime cannot support eye tracking for PC applications.
IMPORTANT: Create and log in with a developer account. You must be a registered developer for the Oculus runtime to expose the hand tracking features.
Ensure that your Oculus software is up-to-date (v49 or later).
Turn on Developer mode on the headset.
Click for details...
On your PC, open the Oculus App, and navigate to Settings and the Beta menu.
Enable Developer Runtime Features.

Considerations for Pimax+Droolon
In order to use the Droolon eye tracking module on your Pimax device, you must first install the aSeeVR SDK.
Once installed, please run the aSeeVR runtime. In the system tray bar, right-click on the runtime, and make sure to enable deviced -> Pimax.
When using Foveated Rendering in the OpenXR Toolkit, adjust the Eye projection distance from the Foveated rendering menu until you reach comfortable sensitivity.
