## Steam
To use Monado as the OpenXR runtime with Steam, or if you're planning to use the SteamVR lighhouse driver in Monado, make sure to [run the room setup first](/docs/steamvr/).
## GPU support matrix
| Manufacturer | Driver | Vulkan Support | DisplayPort Audio | Reprojection Support | Hybrid Graphics Support | Notes |
|--------------|--------------------------|----------------|-------------------|-------------------------------|-------------------------|--------------------------------------------------------------------|
| Nvidia | Proprietary | Very poor | Yes | Functional, non-robust | Crashes | Notable `glcore` crashes with OpenComposite. Proton VR games not playable. |
| Nvidia | Nouveau + NVK Vulkan (Open Source) | Functional | No | No proper Vulkan queue | Untested | Lacks DisplayPort audio, suffers from stutter without reprojection queue. |
| Intel | ANV (Open Source) | Excellent | Yes | Functional, non-robust | Functional | Dedicated cards recommended, lacks robust reprojection like AMD. |
| AMD | RADV (Open Source) | Excellent | Yes | Robust (RDNA and up) | Functional | RDNA generation and up supported with compute tunneling for reprojection. Lower than RDNA are not robust. |
**Notes:**
- **Vulkan Support**: Indicates the level of Vulkan API stability.
- **DisplayPort Audio**: Whether audio over DisplayPort is supported.
- **Reprojection Support**: Describes the support and quality of reprojection features for VR. Poor support indicates that the driver is not able to properly handle Vulkan realtime shaders and it will present as visual stutter. Non-robust solutions will suffer stutter under very high GPU load.
- **PRIME/ Hybrid GPU Support**: Compatibility with systems using multiple GPUs simultaneously. Monado and all clients must be run on a single select GPU due to memory tiling requirements.
- For Nvidia proprietary drivers, only native Linux XR applications are stable. OpenComposite leads to crashes.
- AMD GPUs lower than RDNA generation have functional but less robust reprojection capabilities, expected to be similar to Intel.
- PRIME configurations are generally functional across all but Nvidia's proprietary drivers, which are known to crash with OpenComposite for Steam applications. The open-source Nvidia PRIME support remains untested.
- Audio over displayport is known to temporarily cut out when new audio sources spring up on pipewire.
- X11 configurations are highly discouraged but possible to run, please upgrade your system to Wayland if at all possible.
