OpenXR Switcher

Easily switch between OpenXR runtimes and toggle layers

Download

Description

Reads the Windows registry which OpenXR runtimes/layers are installed, checks if these .json descriptor files are really present (or stale) and lets you enable/disable them quickly.

(-> A PC restart is not required, as those keys are read on VR launch)

Getting Started

Dependencies

• Windows 7, 10, 11
• .NET 6.0 Runtime (if not using the rather big single EXE)
  • Microsoft Runtime Download
  • under .NET Desktop Runtime 6.x.x, next to Windows, click on your arch type (x86, x64) to download the newest runtime
  • Direct Link: Latest x64 Runtime
• !! REQUIRES ADMIN RIGHTS !! (-> the reg keys are located in HKLM!)

Installing

• no installation needed
• just unzip and start the EXE

HowTo - GUI

• if runtimes or layers are not found, they are displayed with an italic font on a yellowish background
• the active runtime and any activated layer will have a green background
• otherwise, the background will be red
• the runtime can be switched to any inactive one
• layers can be en-/disabled as needed (I've added clearer names for known layers like OpenKneeboard)

HowTo - CLI

• the program can also be started via CMD and will let you switch to another runtime without starting the GUI:

• "OpenXR Switcher.exe" /h

• you don't need to specify the exact JSON file name (eg. "steamxr_win64.json"), but some text that can be found

• like: "OpenXR Switcher.exe" steam

• or: "OpenXR Switcher.exe" steamvr

Errors

• if the registry key (HKLM\SOFTWARE\Khronos) cannot be found or written to, you'll get an error message and the program will quit
