### VR initialization error -4: No OpenXR headset or system found
If no OpenXR headset or system is found when launching the ImmersiX application, the Meta Quest Link application is not set-up correctly. Please refer to steps 4-6 in [Getting started](/technologies/immersix/getting-started.md) to set up the Meta Quest Link before starting the ImmersiX application.

### GPU warning
The ImmersiX app requires an NVIDA graphics card (GPU) with the minimum recommended GPU being an NVIDIA GeForce GTX 1080 Ti (see [System requirements](/technologies/immersix/system-requirements.md) for more details). If this warning is shown, your system does either not include an NVIDIA GPU or the available GPU does not meet the minimum system requirements. You will likely observe playback issues when using the ImmersiX application.
