Known controller issues
Windows Mixed Reality controllers are mapped in a wrong way, but don't worry! This will be fixed asap. Other than that, Oculus controllers do not change indicators if you switch to lefthanded mode. We are also on the case here.
SteamVR-Oculus integration issues - "grey room"
We are using SteamVR to provide support for Oculus users. In some versions, this can cause issues outside our control.
Some Oculus users report occasional startup issues where Oculus "takes over" for SteamVR during runtime, causing either strong lag or just seeing a grey room with no controllers.
To fix this, try closing both Oculus and SteamVR (including all background tasks), and starting first Oculus, then SteamVR, allowing SteamVR to "take over".
Enabling "direct mode" can also fix this problem.
