Requirements

Supported headsets

OpenXR Toolkit is compatible with any headset supporting OpenXR on PC. Lately, marketing tends to advertise OpenXR support for certain devices without mentioning whether it is applicable to standalone mode (eg: Android apps) or PC. Fortunately, the majority of headsets can support OpenXR via SteamVR as a fallback, and leverage OpenXR Toolkit that way.

For headsets that do not require the use of OpenXR via SteamVR, please note that using OpenXR via SteamVR is still an option, if you prefer to use SteamVR. OpenXR Toolkit will work both with the native OpenXR runtime and OpenXR via SteamVR.

Please note that if you are interested in using OpenXR Toolkit with OpenVR applications through OpenComposite, that table will tell you a more accurate story than the table below.

[1] Using Oculus via Virtual Desktop or Pico via Virtual Desktop or Streaming Assistant requires to use OpenXR via SteamVR.

[2] Pimax officially only supports OpenXR via SteamVR, however you may consider using PimaxXR to remove the use of SteamVR.

Eye tracking feature

[1] Pico devices do not support eye tracking for PC applications. Pico does not provide the necessary tools to implement it. The marketing of Pico devices is misleading for the consumers, and hurts the developers community: a) Pico marketing claims support for eye tracking without mentioning that this feature is only supported for standalone mode (Android apps) and not available to developers on PC; b) This practice makes us developers look bad for not supporting eye tracking, in spite of the shortcoming being on Pico’s side

[2] 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.

[3] A bug in the Meta OpenXR support prevents certain applications from using eye tracking (due to the Meta Developer mode not being recognized). This is not an issue of OpenXR Toolkit. Please redirect your complaints to Meta!

[4] Pimax Crystal eye tracking will be supported via PimaxXR.

Hand tracking feature

[1] Pico devices do not support hand tracking for PC applications. Pico does not provide the necessary tools to implement it. The marketing of Pico devices is misleading for the consumers, and hurts the developers community: a) Pico marketing claims support for hand tracking without mentioning that this feature is only supported for standalone mode (Android apps) and not available to developers on PC; b) This practice makes us developers look bad for not supporting hand tracking, in spite of the shortcoming being on Pico’s side.

Supported graphics cards

OpenXR Toolkit is compatible with any graphics card supporting DirectX 11, regardless of brand.

Certain features, like Fixed Foveated Rendering and Foveated Rendering, have additional requirements:

Supported applications

OpenXR Toolkit may not work with all OpenXR applications. See the Compatibility list. It can also be used with certain OpenVR applications through OpenComposite.

Limitations

Known issues

• Fixed and Eye-tracked Foveated Rendering in Microsoft Flight Simulator is incorrectly applied in the main menu, resulting in blurry menu windows.
• Fixed Foveated Rendering is not supported in IL-2 Sturmovik.
• Fixed Foveated Rendering in Assetto Corsa requires to lower the “Glare” setting under “Video settings” to Medium or lower.
• Fixed Foveated Rendering in rFactor 2 requires to lower the “Post Effects” setting under “Video setup” to Medium or lower.
• OpenXR Toolkit is not compatible with War Thunder on Varjo headsets.

Installation

Video tutorial by PIE IN THE SKY TOURS:

1. Run the OpenXR-Toolkit.msi program.

📝 Note: You may be warned that Windows protected your PC because this software is not trusted. The application is built on a GitHub server hosted in the Microsoft cloud, which greatly limits the risk of contamination from viruses and malware. Additionally, we have digitally signed the software through a reputable organization (Comodo) which helps with guaranteeing that is has not been altered by any third party.

Proceed through the "Windows protected your PC" warning...

Select More info then Run anyway.

2. Follow the instructions to complete the installation procedure.

📝 Note: You do not need to uninstall the previous version of OpenXR Toolkit if you had one installed. The new version will overwrite the previous one.

3. Launch the OpenXR Toolkit Companion app to confirm that the software is active.

You can use the shorcut found on the desktop or in the Start menu...

The OpenXR Toolkit Companion app may be used sporadically to enable or disable advanced features or perform recovery (see further below). The application displays a green or red status indicating whether the software OpenXR component is active.

The OpenXR Toolkit Companion app can also be used to customize the keyboard shortcuts used to invoke and navigate the menu.

💡 Tip: You don’t need to keep the companion app running in order to use the software: the actual settings for the toolkit are available from within your OpenXR application and display directly in the headset! (see below).

Basic usage

Once installed, please run the desired OpenXR application. A welcome message will appear and instruct you to open the menu:

💡 Troubleshooting: Can’t see the menu? Head to Troubleshooting for help.
