The WMR Portal itself works, MSFS without SteamVR does not. If i select “setup openXR” from the menu (bottom left) in WMR i get a prompt to download openXR runtime from the store - which fails. If i start the XR-toolkit, it tells me, the openXR runtime for WMR is not installed and prompts me to the same page in the store.
So far i just set the steam version of openXR as active runtime and everything works. But since i read, that the WMR runtime gives better performance, i’d like to try that.
